Description

The The invention relates to a device for cutting a porous, essentially rigid plate, in particular laminate floor plate with a frame, a support formed by the frame for the plate, one of the support associated immersion slot and a pivotable on the frame about a pivot axis formed by a pivot bearing such attached cutting blade that its cutting edge during Pivoting the cutting blade from an open position to a closed position immersed in the immersion slot, with one in the pivoting plane horizontal intersection between support and cutting edge during closing the cutting blade from the pivot bearing proximal side of the support towards the pivot bearing distal Side of the pad wanders.

Such a cutting device is known from the FR 575749 , Also the FR 612747 A and FR 847014 A describe such cutting devices.

Of the Invention is based on the object, the generic Further develop the cutting device in a way that is advantageous to use.

Solved The object is achieved by the specified in the claims Invention, wherein not only the independent claims, but also the dependent claims each advantageous developments of Represent the state of the art.

First and essentially it is provided that the pivot bearing, with which the cutting blade is attached to the frame, in the extension direction the immersion slot, so shift in the cutting direction. According to this embodiment, by using a stopper also a laminate board that is wider than the effective one Cutting length of the cutting blade. The cut can be in several successive steps are performed, wherein the laminate plate remain in its contact position at the stop can. It will not be the laminate panel opposite the frame, but shifted the cutting blade relative to the frame. In a further development of the invention, a locking mechanism is provided, which blocks the slidability of the pivot bearing, if that Cutting blade by a predetermined pivot angle from the open position has been pivoted in the direction of the closed position. In the Open position, the cutting blade is preferred by about 90 ° the support swung open. In this open position leaves the pivot bearing extends in the extension direction of the immersion slot, So shift in the cutting direction. As soon as the cutting blade is around one certain angular amount from this fully open Position is shifted towards the closed position, ie with the beginning of the cut, the locking mechanism comes into effect. The latter preferably has an eccentric cam. This eccentric cam is rotatably connected to the cutting blade. He turns, when the cutting blade is pivoted. The eccentric cam forms a radial board, which cooperates with a terminal block. He moves the terminal block against a supporting flank of the frame, so that the terminal strip frictionally engages there. This creates a braking force that the displaceability of the Swivel bearing blocked against the frame. The eccentric cam is part of a pivot axis, with which the cutting blade in bearing supports is stored. The bearing carrier preferably form a bearing link out. The latter can be formed by two link elements. The Bearing guide is preferably linearly on guide ribs guided. The guide ribs can of protrude two spaced opposite guide walls and have a dovetail contour. These dovetail webs engage in dovetail grooves of the bearing block. The two Sliding shells can be formed from plastic injection molded parts be. These can form a bag in which the Terminal strip is located.

A Further development of the generic state of Technique relates to the design of the cutting edge of the cutting blade. The latter has spaced apart teeth that are when closing the cutting blade successively in such bury the surface of the plate to be cut, that the plate during cutting only slightly shifted in the cutting direction becomes. According to such a configuration, the use of a Stop be dispensed when an endless cut done shall be. The teeth preferably have two in each other apex flanks. The flanks of adjacent teeth are by straight or slightly curved sections the cutting edge spaced from each other. The with their flank surface flanks pointing to the axis of rotation have a steeper angle of attack as the groundbreaking with their flank surface of the pivot axis Flanks.

According to a further development of the prior art, teeth are provided in the region of the support. These teeth are for holding the workpiece on the support and are able to dig into the back of the workpiece when a pressure is applied to the workpiece from above. To avoid a risk of injury in the open position of the cutting blade is proposed that the teeth change during pivoting of the cutting blade from the open position in the direction of the closed position of a hidden position in a leading position. It can be provided that the teeth when Verschwen ken the cutting blade in the open position in a recessed position. As soon as the cutting blade is displaced from the open position in the direction of the closed position, the teeth change from the hidden position to the initial position. The teeth are preferably assigned to a toothed strip. This rack is inserted in a receiving groove which extends parallel to the immersion slot. On both sides of the immersion slot such receiving grooves can be provided, which are each equipped with a rack. The toothed racks can be raised and lowered. In a further development it is provided that the teeth, which may also be formed by a rack, sit firmly on the frame. The teeth also run in rows parallel to the immersion slot. There is a bar next to the teeth. The surface of the strip having a substantially rectangular cross-section forms the support for the plate to be cut. In an unloaded state, the imaginary plane, in which the top of the strip lies, overhangs the tips of the teeth. The top of the bar can be displaced in the downward direction by applying a pressure. For this purpose, the strip may be formed from a compressible, in particular rubber-elastic material, for example foam rubber. The downward displacement of the top of the bar is done for example by supporting the plate to be cut or by exercising the cutting force. The top migrates down below the tips of the teeth, so that the teeth of the row of teeth can dig into the bottom of the plate. A row of teeth and a strip extend in each case on both sides of the immersion slot, the two rows of teeth extending between the two strips extending parallel to one another.

A further development of a generic laminate cutter concerns the design of the frame. The latter is preferred by formed one or more hollow bodies. Preferably owns the frame has two substantially identical, mirror-symmetrical mutually arranged hollow body. In the hollow bodies they are preferably aluminum extrusions. The two front ends the hollow bodies are preferred with face panels connected. These front panels can also be the Training feet of the cutter. The Face panels hold the two hollow bodies in such a distance from each other that between them the Immersion slot trains. The two hollow bodies form above it in addition, the two above, spaced apart Guide walls on which the bearing guide led is.

In a further development of a generic Laminate cutter is provided that removes from the bearing axis lying end of the cutting edge forms a last tooth. Its from the pivot axis groundbreaking tooth flank crosses the pad when Closing the cutting blade substantially at right angles. As a result, this last tooth produces a substantially perpendicular to the Cutting direction extending end edge in section. This last tooth is adjacent a bump stop.

A further development of a generic laminate cutter concerns the attack. This one comes with a fixing screw fastened above the support, with the fastening screw through protrudes through the immersion slot and screwed into a clamping slot is. The tensioning backdrop is supported below the support in the area between the two hollow bodies, which is the Frame form, at stiffening webs. They are friction enhancing Elements provided with which the tensioning backdrop is supported on the stiffening ribs. In addition, detent webs protrude from the tensioning scenery. These reach through the immersion slot and into a recess of the stop to fix it in a 90 ° position. There may be provided a plurality of recesses to the stop also in a 45 ° position or, for example, in a 30 ° or 60 ° position to fix.

A further development of a generic laminate cutter relates to a hold-down. If a laminate slab to be sliced is divided stepwise by incomplete individual slices, then the slicing knife must be swung back after every single cut through the generated slit gap. However, the flanks of the cutting gap adhere frictionally to the broad side surfaces of the cutting blade, so that there is a tendency to raise the plate to be cut when opening the cutting blade from the closed position. This, considered disadvantageous lifting is prevented by the erfindungsge MAESSEN hold-down. The latter acts on the upper side of the plate in the direction of the support when the cutting blade is pivoted from its closed position to the open position. Preferably, the hold-down is formed by a lever arrangement. The lever arrangement may be associated with the cutting blade. For this purpose, a two-armed actuating lever is preferably articulated on the cutting blade. The operating lever has a holding-down arm, whose end in the course of the opening movement of the cutting blade acts on the plate to be cut from above. This is preferably done with the free end of the hold-down. The second arm of the actuating lever forms a handle arm, at the end of a handle is attached. The pivot bearing, with which the actuating lever is attached to the cutting blade, may be formed by a screw. In a preferred embodiment, the actuating lever of two identically shaped metal, in particular steel plates is formed, the between to pick up the cutting knife. It is provided a stop limit, with which the pivot angle of the actuating lever is limited relative to the cutting blade. For this purpose, a stop pin connecting the two steel plates with one another can pass through an arc slot of the cutting blade. Furthermore, a locking device is provided with which the pivoting of the actuating lever relative to the cutting blade can be blocked. The lock preferably consists of a knob which is screwed onto a threaded pin. In the blocking position, the threaded pin lies in an open-edged slot of the cutting blade. By tightening the knob, the two steel plates forming the operating lever are pressed against the broad sides of the cutting blade.

A further development of a generic laminate cutter concerns the design of the cutting blade. It is provided that the cutting knife extends between the chest and the back Having the cutting blade extending cross-section reduced zone, which runs in the open position of the cutting blade parallel to the support. This cross-section reduced zone thus extends in a straight line between the incisor edge and the incisor edge groundbreaking back. This cross-section reduced zone has two parallel edges. In the open position of the cutting blade runs the lower Edge of the reduced cross-section zone below the overlay. Of the upper edge of the cross-section reduced zone runs above the edition. The upper edge is spaced far enough from the support, so that it is above the surface of the to be cut Plate runs. The cross-section reduced is preferred Zone of two groove-like depressions formed in the two incorporated opposite broad sides of the cutting blade are. The edges of the cross-section reduced zone become thereby formed by stages. These cross-section reduced zones prove to be advantageous when using the laminate cutter in several consecutive cuts a wide laminate plate should be cut. After the first cut, the cutting knife becomes brought into the open position. The manufactured in this first cut Partial section has a width that is larger than the material thickness of the cutting blade in the cross-section reduced zone. In the open position runs this cross-section reduced zone immediately above the support, so that the laminate plate is almost frictionless relative to the Cutting knife can be moved further. Alternatively, it can also the cutting blade in the manner already described above relative be moved relative to the frame. It moves the reduced cross-section through the cut into the laminate plate Member slot.

A further development of a generic laminate cutter concerns a support block. The support frame is temporary attached to the frame. The attachment can over a Rest or clip connection done. At the support block acts it is preferably an arcuate part, which on the frame formed by two hollow bodies is placed. Here is a head section of the support bracket above the edition of the frame. Two foot sections each form a lower one Border edge with which the support stand is placed on a base can be. Between the foot section and the head section a middle section extends. The latter has a cross-sectional contour line, which follows the outer wall of the frame. The height the support bracket corresponds to the height of the frame. Of the Support bracket can be at a distance from the frame to the ground be put on. His head is then about the same Amount spaced from the ground as the support of the frame. The support bracket serves to rest a plate to be cut.

The frame 2 of the laminate cutter is formed by two substantially mirror-symmetrically arranged hollow bodies, which are manufactured in the aluminum extrusion process. The two hollow bodies each have a bottom wall 46 , an exterior wall 43 , an inner wall running parallel to the outer wall 44 and one between the outside wall 43 and inner wall 44 extending guide wall 45 on. While the guide wall 45 Essentially extending in the vertical direction, the bottom wall extends 46 essentially in the horizontal direction.

The two housing halves are spaced apart. The distance between the two housing halves defines a slot 4 , The slot extends between two web extensions 55 , each supporting flanks 18 form. At the two aligned ends of the Abstützflanken 18 are stiffening webs 19 that form an open-topped pocket.

At the top, the bridge extensions form 55 an edition 3 for a laminate board 1 , In the two parallel to the immersion slot 4 extending pockets are each toothed racks 20 one. There may be provided an unillustrated mechanism to these racks 20 to shift in the vertical direction.

In the embodiments shown in the drawings, the toothed racks 20 but firmly in the grooves 50 , Next to each other on each side of the slot 4 extending toothed racks 20 lie in depressions 56 the bridge extensions 55 Foam rubber strips 53 one. The upward-facing surfaces of the foam rubber strips 53 lie in a common plane E, which is above the peaks 52 the teeth 51 the rack 20 runs. The strips 53 can be compressed. This is done by a vertical pressure from above. In the unloaded state, the plane E of the tops of the strips runs 53 over the tips of the teeth 52 , so that a risk of injury is minimized. Will - as in the 20 is shown - on the top of the strips 53 a laminate board 1 placed and on the latter a vertical pressure applied downward, so the top of the strips shifted 53 according to a compression of the latter down. The tips 52 the teeth 51 can be in the bottom of the plate to be cut 1 dig.

Is located on the frame 2 hinged cutting blade 6 in the in 1 shown fully open position, are the teeth of the rack 20 in a hidden position. They are in a recessed position relative to the edition 3 forming top of the ledges 53 , Will the cutting knife 6 from the in 1 illustrated open position in a clockwise direction in the Closed position shifted, with the intersection 8th between cutting edge 7 and edition 3 towards a stop 22 shifted, the toothed ridges occur 20 out of the recessed position. You can thus dig into the bottom of the laminate plate to fix it.

The two housing halves are by means of front side panels 40 , which can be made of plastic, fixed to each other. These face panels also form the feet, with which the frame 2 can be placed on a level surface. They tower over the bottom wall 46 , In the area of the corner between the bottom wall 46 and inner wall 44 there is a guide slot 47 , The two opposite guide slots 47 the two housing halves form a guide for a drawer designed as a plate 39 out. With this drawer 39 can the space between the two housing halves close. This space forms a chip collection chamber. A floor panel of the drawer 39 sits at an end plate 42 with the drawer closed in a recess 41 the front side panel is located. There are two drawers 39 provided that can be inserted from the opposite ends.

The cutting knife 6 has at its bearing end a bearing opening and at its other end a handle. A directly to the bearing end at closing edge of the cutting blade 6 forms a cutting edge 7 out. The opposite edge forms the back of the cutting blade 6 and is essentially straightforward. The cutting edge 7 runs so arcuately that when closing the cutting blade 6 the point of intersection 8th between edition 3 and cutting edge 7 from the pivot bearing of the cutting blade 6 moved away. The arcuate cutting edge 7 has a plurality of spaced apart teeth 17 , The to the pivot bearing axis 5 indicative flanks 17 '' the teeth 17 have a steeper angle to the contour line of the cutting edge 7 , as the tooth flanks pointing away from the pivot bearing 17 , As a result of this configuration, the teeth dig 17 when closing the cutting blade 6 successively into the surface of the laminate plate 1 so as to prevent slippage of the laminate plate 1 during the cut.

The laminate cutter can be used to cut laminate sheets that are wider than the length of the cutting edge 7 , Such a laminate plate 1 is with a marginal edge against a contact edge of the angle stop 22 laid, with the angle stop 22 a greater spacing to the pivot bearing axis 5 has, as the length of the cutting edge 7 , In a first cut, starting from the in 1 shown position of the cutting blade 6 produced a first partial section. The cutting knife 6 is there at the maximum distance from the angle stop 22 , The cutting knife 6 can in the in 1 illustrated, fully open position in the direction of the angle stop 22 be relocated. For this purpose, the user at one on the back of the cutting blade 6 attached handle 21 attack.

The subsequent cut can then be made from the in 2 shown operating position, in which the cutting blade 6 closer to the stop 22 is stored.

To enable the previously described operation, the pivot bearing axis 5 from a warehouse setting 9 stored along the guide walls 45 can be moved in the cutting direction. The pivot bearing axis 5 consists of two bearing halves with a bearing eye of the cutting blade 6 thorough connection screw 13 connected to each other. The two axially facing away from each other end portions of the pivot bearing axis 5 form eccentric sections 12 out. A first section 12 ' consists of a tangential surface. At this secant surface 12 ' closes a circular cylindrical surface 12 '' at. The circular cylindrical surface 12 '' is in a warehouse opening 14 a backdrop shell 9 stored the bearing block. The eccentric section 12 also owns a stop 12 ''' ,

The scenery bowls 9 store each one of the two mutually pioneering eccentric sections 12 and form after the bearing opening 14 each bags 10 out, in each of which a terminal strip 11 rests. The scenery bowls 9 also form dovetail grooves 16 out, into the dovetail webs 15 intervention. The dovetail webs 15 run on the outer sides of the guide walls 45 , thus face each other and extend parallel to the immersion slot 4 , The terminal strips 11 lie on one side of the eccentric section 12 the pivot bearing axis 5 at. On the other side are the terminal strips 11 on the supporting flanks 18 at.

In the in 7 illustrated open position of the cutting blade 6 lies the flank running on a secant 12 ' of the eccentric section 12 in the bottom plane of the bag 10 so that the terminal block 11 not against the supporting flank 18 is pressed.

In this operating condition is the stop 12 ''' at a counter stop of the backdrop shell 9 , The bearing block 9 can thus in the extension direction of the immersion slot 4 be moved. She glides along the dovetail webs 15 ,

Will the cutting knife 6 pivoted in the direction of its closed position, so is the terminal block 11 from the peripheral section 12 '' applied. The terminal block 11 then presses against the supporting flank 18 , so that the displacement of the bearing block 19 is frictionally blocked.

The angle stop 22 lies on the pad 3 on and has an opening 30 through which a screw 23 is plugged. The opening 30 is with a stopper 31 closed, the head of the screw 23 engages over. The threaded shaft of the screw 23 is in a threaded hole 27 a tensioning backdrop 24 screwed. The tensioning scenery 24 is located in the space between the two guide walls 45 , It has two in the immersion slot 4 protruding ridges 28 that's up over the run 3 can protrude. The tensioning scenery 24 also has two parallel grooves 26 in which threaded pins 25 einliegen as Reibschlussvergrößernde elements. When tightening the screw 23 become the shell walls, so the threads of the rib body 25 , against the stiffening webs 19 pressed. It thus creates a frictional assurance of the angle stop 22 against shifting.

If very wide plates are to be cut, ie those whose width is the length of the frame 2 can exceed the angle stop 22 by loosening the screw 23 be removed. For captive retention of the clamping scenery 24 in the space between the two guide walls 45 , protrude from the bottom of the clamping scenery 24 each clamping tongues 29 off to the dovetail webs 15 can support.

In a 90 ° or 45 ° angular position of the angle stop 22 grips a detent 28 in a detention niche 34 of the angle stop 22 one. For adjusting the angle stop 22 in another angular position is the screw 23 solved.

The device has optional stiffening means. These consist of two mutually parallel steel rails 36 , the support flank below the Ab 18 are arranged and the displacement of the bearing block 9 restrict. The stiffening rails 36 are with several Befestigungsbäckchen 37 in the space between the guide walls 45 attached. For attachment serve the dovetail webs 15 , For stabilization there are two on different sides of the immersion slot 4 arranged stiffening rails 36 by means of connecting webs 38 connected with each other. The connecting bridges 38 connect two holding bones each 37 together.

The last tooth already mentioned above 48 forms the cut end of the cutting edge 7 , This last tooth 48 is a stop buffer 49 adjacent to the handle end of the cutting blade 6 located.

That in the 21 and 22 illustrated embodiment substantially corresponds to the embodiment described above, but here on the end plate 42 a kick 57 is provided. Essential in this embodiment is the design of the cutting blade 6 , While in the embodiment described above, the handle is seated on an arm of the cutting blade, the material of the same blade is formed integrally, in this embodiment, the gripping arm 59 from one arm of a two-armed operating lever 58 educated. At the end of the handle arm 59 is the handle 62 placed. It consists of two handles.

The operating lever 58 consists of two substantially identically shaped steel plates, which between them the steel cutting knife 6 take up. The two the operating lever 58 forming steel plates are with a hinge axis 61 connected with each other. The hinge axis 61 extends through a joint hole of the cutting blade 6 , Around this hinge axis 61 can the operating lever 58 relative to the cutting blade 6 be pivoted. To limit the pivot angle of the operating lever 58 opposite the cutting blade 6 Slings are provided. These consist of a stop pin 65 who has a bow slot 66 of the cutting blade 6 be upheld. The two ends of the arched slot 66 limit the tilt angle of the operating lever 58 ,

The second arm 60 of the operating lever 58 extends approximately at a 180 ° angle to the first arm 59 , Both arms 60 . 59 are about the same length. The free end 60 ' of the second arm 60 is capable of holding down a plate to be cut 1 auszuübert. Accordingly, the second arm of the operating lever forms 58 a hold-down arm 60 out. The swivel angle of the operating lever 58 and the length of the hold-down arm 60 are so on the location of the axis of rotation 61 turned off that when opening the cutting blade 6 from a closed position towards an open position the end 60 ' the edition 3 but at least the top of a laminate board to be cut 1 applied downward. Opening the cutting blade 6 is thus not only a pivoting of the cutting blade 6 , but also with a relative pivoting movement of the operating lever 58 opposite the cutting blade 6 connected, with the free end 60 ' of the hold-down arm 60 from the axis of rotation A of the cutting blade 6 removed and on top of the cut laminate board 1 glides along while keeping a force on the laminate plate 1 which exercises towards the pad 3 is directed.

It is a locking device 63 provided, which consists of a threaded pin and a screwed on knob 63 , The cutting knife 6 has an open-edged slot 64 into which the threaded shaft can enter. Will the knob in this position 63 locked, so is the pivoting of the operating lever 58 blocked, because the cutting knife 6 between the two steel plates of the operating lever 58 is trapped.

The operation of the hold-down is the following: Is for cutting a wide laminate plate 1 a multiple cut required, so the cutting knife 6 after each cut through the kerf in the laminate plate 1 be swung back to the top. Since the walls of the kerf friction fit on the broad side surface of the cutting blade 6 cling, there is a tendency, the laminate plate 1 when opening the cutting blade 6 to raise. With released lock 63 becomes when lifting the handle arm 59 but a torque on the operating lever 58 exercised, as this smoothly around the axis of rotation 61 is pivotable. The hold-down arm 60 Tilts down until its end 60 ' in contact with the top of the laminate plate 1 occurs. The end 60 then rests against the top of the laminate plate 1 and forms a fulcrum to which the operating lever 58 then turns when the handle 62 is pulled further up. The cutting knife 6 is then pulled out of the cut slot, with the same time over the ends 60 ' a hold-down force on the laminate plate 1 is exercised.

For the subsequent cut is either the cutting blade 6 towards the angle stop 22 moved or the laminate board to be cut 1 towards the cutting knife 6 relocated. After that, the handle 62 again loaded in the downward direction, so first pivoted the operating lever 58 in its stop position, in which either the stop pin 65 at the top of the arch slot 66 or the threaded shaft at the bottom of the open-edged slot 64 strikes. When this pivoting end position is reached, it is possible to use the handle arm 59 and then its rigid coupling with the cutting blade 6 a torque on the cutting blade 6 be applied so that the next cut can be made.

Also in this embodiment is located below the immersion slot 4 a pull-out plate that holds a drawer for holding chips 39 forms. In this embodiment, however, the plate is not splits branches. It is a single, extending over the entire length of the frame 2 extending plate provided.

The two respectively the ends of the two mutually parallel hollow sections of the frame 2 closing face panels 40 form end caps, with their bottom a footprint 78 form, with the laminate cutter can be raised to a base. From the end caps 40 protrude from both sides wings, each with a mounting hole 67 are provided. In these mounting holes 67 Fixing screws can be screwed in to permanently fix the frame on a worktop.

That in the 21 to 29 illustrated embodiment has only one drawer 39 with which the below the immersion slot 4 formed cavity is closed. Also in this embodiment, the drawer 39 essentially of a sheet metal strip, which at its end an end plate 42 has. The end plate 42 forms a handle with which the drawer 39 can be pushed back and forth in a guide.

The cutting edge 7 of the cutting blade 6 also forms a fine toothing in this embodiment. These are teeth with a tooth height of about 1.5 mm and a pitch of 3 mm. This gearing forms the breast 6 ' of the cutting blade. The breast 6 ' runs on a contour line, which is designed arcuate. The breast 6 ' opposite edge of the cutting blade forms her back 6 '' , The latter runs essentially straight and carries a plastic handle 21 ,

Between plastic handle 21 and pivot bearing axis 5 there is a cross-section reduced zone. This cross-section reduced zone is characterized by two Breitseitenausnehmungen 68 educated. These are groove-like depressions 68 , The two only a few tenths of a millimeter deep grooves 68 run parallel to each other and are the wide facing away broad sides of the cutting blade 6 assigned. The two grooves 68 have a lower level 70 and an upper stage 69 , which run parallel to each other. In the in the 25 and 26 illustrated fully open position of the cutting blade 6 the steps go 69 . 70 parallel to the edition 3 , While in this open position, the groove extends in the horizontal direction, runs the back 6 '' of the cutting blade 6 in vertical direction. The lower level 70 the depression 68 lies below the edition 3 , The upper level 69 the depression 68 lies above the edition 3 , The distance of the upper step 69 for circulation 3 is greater than the material thickness of the plate to be cut.

The function of the bilateral depression 68 or the thus achieved cross-section reduced Zone is explained below: Is to cut a porous plate, such as laminate plate, whose width is greater than the effective length of the cutting edge 7 of the cutting blade 6 , so the plate must be cut in several successive cuts. There is first a first cut, which extends only over part of the width of the laminate plate. This is done by pivoting the cutting blade 6 from an open position to a closed position. Thereafter, the cutting blade must be swung out of the partial section again. This is done with the help of the above-described hold-down 60 and its hold-down functional surface 60 , The cutting knife 6 will be in the in the 25 and 26 pivoted full open position shown pivoted. When opening the cutting blade 6 beats while the stop pin 65 at one end of the arch slot 66 like this in the 25 is shown. In the fully open position, in which the back 6 '' of the cutting blade 6 runs approximately in the vertical direction, the cross-section reduced zone runs 68 in the horizontal direction immediately above the support 3 , That on the pad 3 lying workpiece can now be moved further or it can be the cutting blade 6 towards the stop 22 be relocated. This results in a relative displacement of cutting blade 6 and laminate board 1 , This shift is therefore smooth, since only the cross-section reduced range 68 through the slot of the laminate plate 1 is moved. The bottom of the wells 68 has a small distance to the walls of the cut gap in the laminate plate 1 , so that a sliding friction reduction takes place.

The 27 and 28 show a aufklipsten on the frame support bracket 71 , The latter consists of a U- or V-shaped molding whose inner cross-sectional contour is approximately the outer cross-sectional contour of the frame 2 equivalent.
