Description

The invention relates to a blanket unit for a blanket cylinder and to a method for producing a blanket unit according to the preamble of claim 1 or 30.

Blanket units are mounted in rotary printing presses on the blanket cylinder and are used in offset printing of the transfer of the print image from the forme cylinder to the printing substrate. In order to give the blanket unit the required mechanical strength, a support plate, for example made of sheet steel or aluminum sheet, is used. On the outside of the support plate, a blanket, which may be formed, for example, in the manner of a blanket attached. To fix the blanket unit on the blanket cylinder bent, blanket-free leg are provided at the leading end and / or at the trailing end of the carrier plate. These legs can then be introduced, for example, in a slot provided on the blanket cylinder and fixed there.

A problem with known blanket units is that the blanket does not seamlessly enclose the carrier plate, but leaves a gap between the leading and trailing ends of the blanket. In the area of this gap no ink can be transferred to the substrate web. At the edges of the blanket towards the gap is also the printed image of poorer quality. From the prior art, therefore, various solutions are known with which the disadvantages caused by the gap between the ends of the blanket can be avoided.

From the DE 195 47 917 A1 a printing blanket unit is known in which the two ends of the printing blanket overlap one another in a form-fitting manner, thereby separating the gap to shrink between the ends of the blanket.

From the DE 195 21 645 A1 a printing blanket unit is known in which a slider is arranged between the two legs of the carrier plate. The outwardly facing end of the slide is connected to a filler, so that the gap between the ends of the blanket is closed by the filler.

From the DE 195 43 584 C1 a printing blanket unit is known in which the blanket is composed of a plurality of layers. The cover layer covers the end faces of the underlying layers and thus forms a projection by which the gap between the ends is reduced.

The US 5,749,298 A discloses a printing blanket unit with a carrier plate whose ends are folded. The printing blanket arranged on the carrier plate is sealed on the front side.

The US Pat. No. 4,635,550 discloses a blanket unit having a blanket disposed on a carrier plate. In the channel, a support element is arranged on the support plate, which supports the protruding end of the blanket.

The US Pat. No. 2,525,003 A shows an apparatus for producing a printing blanket unit.

The US 4,643,093 A discloses a pressure plate with reinforced end and associated apparatus.

The invention has for its object to provide a blanket unit for a blanket cylinder and a method for producing a printing blanket unit.

The object is achieved by the features of claims 1 or 30.

An advantage of the printing blanket unit according to the invention is in particular that the leading and / or trailing end of the blanket protrudes with its inside a piece over the fold of the associated leg. This projection reduces the gap between the ends of the blanket. It is quite conceivable that the supernatant is chosen so large that the two ends of the blanket come into contact with each other in the installation position. Due to the fold of the support plate, the protruding ends of the blanket are not supported by the support plate from below, so that without further aids no pressure between the blanket and the printing material in the region of the protruding ends could be established. To solve this problem, it is proposed between the fold of the support plate and the inside of the blanket to arrange a support member for supporting the supernatant. As a result, the pressure forces are then transferred from the blanket via the support member to the support plate, so that the printed image can be imprinted properly on the substrate web even in the region of the protruding ends of the blanket. Whether it is provided at both ends of the blanket or only at one end of the blanket, a support member for supporting the supernatant is basically irrelevant.

For the attachment of the support elements to the blanket unit diverse fastening solutions are conceivable. According to a preferred embodiment, the support elements are firmly bonded to the fold and / or on the inside of the blanket, in particular glued or vulcanized.

The support elements can be produced in a particularly simple manner if they are made of the same material as the blanket, for example of rubber, or of the same material as the carrier plate, for example metal. In particular, it is then conceivable to form the support elements in one piece to the blanket or the carrier plate.

In the production of the support elements, it is also conceivable that the support elements are materially connected to a base layer, which is arranged between blanket and carrier plate and in this way the carrier plate, starting from the two folds, continuously wraps around. Due to the undercoat layer, the properties of the printing blanket unit, in particular with regard to the hardness and the concentricity, can additionally be influenced. Rubber or a similar elastomeric material is particularly suitable as material for the production of the undercoat layer.

By using the manufacturing method according to the invention can be produced in a simple manner blanket units having a minimum gap. For carrying out the method, a production cylinder may be available whose shape, in particular its diameter and its fastening devices for fastening the carrier plate, essentially corresponds to the blanket cylinder used later in the printing machine. At this manufacturing cylinder, the uncoated carrier plate is attached to the folded legs and takes in this way a position corresponding to the later position after mounting on the blanket cylinder.

After attachment of the carrier plate on the production cylinder, the gap between the opposite folds of the carrier plate with a support material, for example, with a curable rubber compound, filled. In this way, the two folds of the support plate are firmly bonded together.

Subsequently, the blanket is attached to the support plate, for example, glued or vulcanized that at least one end of the blanket projects a piece over the fold of the associated leg. The supernatant is then in this way on the support material and is supported by the support material from below.

In order to remove the blanket unit from the production cylinder, the support material is cut before or after the attachment of the blanket to the support plate to form two support elements. This can be done, for example, that the support material is cut with a sharp edge. The two side surfaces formed by the separation process of the opposite Support elements have in this way a shape, so that the support elements after assembly of the blanket unit on the blanket cylinder opposite each other form complementary with a short distance or come to rest.

In order not only to ensure optimal support of the supernatant at the end of the blanket, but also to minimize or eliminate the gap between the two ends of the blanket, a preferred method variant is used. In this variant of the method, the usual printing blankets are used, which have a flat shape, for example a rectangular shape, before the printing blanket is attached to the carrier plate. By attaching the blanket to the carrier plate, a gap is formed between the mutually facing side surfaces at the opposite ends of the blanket using these flat blankets. This gap is filled with a suitable sealing material, such as a curable. Rubber mass, filled. In order to remove the blanket unit from the production cylinder, the sealing material is then severed after sufficient curing. The side surfaces of the opposite ends of the blanket formed by the separation process have a shape such that the ends of the blanket after mounting the blanket unit on the blanket cylinder opposite each other in shape complementary with a short distance or come to rest against each other.

In order to achieve the most accurate concentricity, it is particularly advantageous if the sealing material processed before or after the cutting to form a cylindrical peripheral surface, for example, ground, is.

Preferably, the sealing material and support material are cut through at the same time in order to ensure an optimal form fit between the opposite ends of the blanket unit when mounting the blanket unit on the blanket cylinder.

Embodiments of the invention are illustrated in the drawings and will be described below.

an embodiment of the blanket unit according to Fig. 3 with thickened ends.

In the Fig. 1 to Fig. 12 shown printing blanket unit whose thickness d01 z. B. 1.6 mm, consists of a dimensionally stable support plate 02; 18; 42, with a thickness d02 of about 0.2 mm to 0.5 mm and one on the support plate 02; 18; 42 attached blanket 03; 19; 43. The support plate 02; 18; 42 is made of metal, for example of a steel sheet or aluminum. The blanket 03; 19; 43, for example, in the manner of a blanket 03; 19; 43, in particular of several layers of different material, be formed.

In a folding machine are at the leading and the trailing end of the support plate 02; 18; 42 the blanket-free leg 04; 06; 21; 22; 44; Folded down 46 so that the legs 04; 06; 21; 22; 44; 46 can be used later to attach the blanket unit to a blanket cylinder 05. The angled leg 06; 21; 46 at the leading end closes with the at the leg 06; 21; 46 adjoining middle part 07; 35; 47 of the carrier plate 02; 18; 42 an acute opening angle α06, in particular from 30 to 60 degrees, preferably from 40 to 50 degrees, a. The angled leg 04; 22; 44 at the trailing end points with the adjoining support plate 02; 18; 42 an opening angle α04 of 45 to 150 degrees, in particular from 80 to 100 degrees, on. In a preferred embodiment the angle size is 120 to 150 degrees. Between the legs 04, 06; 21; 22; 44; 46, the middle part 07 runs; 35; 47 of the carrier plate 02; 18; 42, of the blanket 03; 19; 43 is completely covered to the outside. At the transition between the middle part 07; 35; 47 on the one hand and the legs 04; 22; 44 or 06; 21; 46 on the other hand, the bends run 08; 09; 27; 28; 48; 49th

In the in Fig. 1 The production phase shown, both the support plate 02 and the blanket 03 are designed approximately flat, so that the blanket 03 can be fixed tension and deformation on the support plate 02. For this purpose, the blanket 03, for example, glued and / or vulcanized.

Subsequently, in a folding machine, the blanket-free legs 04 and 06 are folded downwards ( Fig. 2 ).

The folds 08 and 09 are produced in the bending machine such that the two ends 11 and 12 of the blanket 03 a piece far beyond the folds 08 and 09 survive. The space between the protruding ends 11 and 12 of the blanket 03 on the one hand and the support plate 02 on the other hand is filled by filling compound 13; 14, also referred to as support member 13 and 14, filled. The filling compound 13 and 14 can be produced for example by applying a curable rubber compound.

Preferably, the filling compound 13; 14 deformable during insertion and / or flowable.

In Fig. 3 a section of the blanket unit is shown in the installed position. It can be seen that the two legs 04 and 06 extend in the installed position opposite each other parallel to each other, so that they can be fastened together in a slot on a pressure cylinder, not shown. Due to the projection of the ends 11 and 12 of the blanket 03, the width of the gap 16 between the ends 11 and 12 of the blanket 03 is minimized. This makes it possible, for example, to minimize the width of the gap 16 to a width of less than 0.5 mm.

The distance between the bends 08; 09 substantially corresponds to the distance a01 of the opening on the cylinder surface and is less than 3 mm, in particular it is smaller than 2.0 mm.

Due to the support of the protruding ends 11 and 12 by the filling compound 13 and 14, a sufficient pressure transfer from the blanket 03 is achieved on a printing substrate in this area.

As in Fig. 4 illustrated, the distance a02 of the opposite ends 11; 12 of the blanket 03 0.2 mm to 0.8 mm, preferably 0.3 mm to 0.7 mm. In a particularly preferred embodiment, the distance a02 is 0.4 mm to 0.6 mm, in particular 0.5 mm.

The fold 08 of the leg 04 has a radius R of 0.6 mm to 1.2 mm, in particular of 0.8 mm.

The bevel 09 of the leg 06, however, has a radius R of 0.3 mm to 0.7 mm, in particular of 0.5 mm.

The length L13; L14 of the respective support element 13; 14 is in the circumferential direction 0.4 mm to 1.0 mm, in particular 0.1 mm to 1.3 mm. In a preferred embodiment, the length L13; L14 of the support member 13; 14 at 0.7 mm.

As in Fig. 4 illustrated, the filling compound 13; 14 may be formed in different shapes. Thus, the filling material 13 z. B. an acute angle, while the filling material 14 is formed at right angles.

The for the Fig. 4 described dimensions can be transferred substantially to all embodiments shown in the figures.

In Fig. 5 a third embodiment of a blanket unit is shown. This blanket unit also has a support plate 18 made of sheet steel and a blanket 19 made of rubber. To produce the printing blanket unit, the support plate 18 is first attached with its legs 21 and 22 to a production cylinder, the shape of which corresponds to the blanket cylinder to which the blanket unit is to be fastened in the printing press. Subsequently, a sealing member 23 is inserted into the gap 26 between the legs 21 and 22 to seal the gap 26 down. Thereafter, a liquid elastomer composition is applied to the outside of the support plate 18 such that the support plate 18 is surrounded by a continuous Unterbauschicht 24. In the region of the opposite legs 21 and 22, the sub-base layer 24 fills the gap 26 between the opposite folds 27 and 28.

Subsequently, the blanket 19 is attached to the base layer 24, for example, vulcanized. The gap 26, which continues between the ends 31 and 32 of the blanket 19, is closed with filling material, here also referred to as sealing material 29, for example, a curable elastomer composition, closed and then ground on the outside to produce a uniform cylindrical outer surface.

Finally, the sealing material 29 and the subgrade layer 24 are severed along the cutting line 33, so that the printing blanket unit can be removed from the production cylinder and mounted on a blanket cylinder. By separating the base layer 24 separate support members 34 and 36 are formed, each of which supports the ends 31 and 32 of the blanket 19 from below. When mounting the printing blanket unit on a blanket cylinder, the side surfaces of the support elements 34 and 36 formed by the cut along the section line 33 can come into positive engagement with one another.

The FIGS. 6 to 8 show embodiments of another manufacturing method for a blanket unit similar to that of Fig. 3 ,

Here, at least one end of the support plate 42, as already described, angled.

The support plate 42 is now on a base 53 of a device 41 with at least one slider 54; 56, as described below, launched. At least one of the sliders 54; 56 is the main body 53 and / or the other slider 56; 54 mobile. This basic body 53 is adapted in its geometry to the geometry of the carrier plate 42. Both slides 54; 56 of the device 41 are open. The carrier plate 42 is then adjusted to the necessary cylinder circumference or to the necessary Abkantmaß means of an adjustment mechanism 57. Both slides 54; 56 are closed. The filling compound 51; 52 is then poured or pressed positively. Depending on the shape of the slider 54; 56 becomes a shallow, d. H. with the support plate 42 flush, or achieved an elevated base, the slider 54; 56 as form 54; 56 for the filling material 51; 52 act. At least one of the filling compounds 51; 52 stands on the virtual extension V42 of the outside of the support plate 42 in the radial direction addition. The filling compound 51; 52 is then pulled flush by a further device 58 or ground. Subsequently, the blanket 43 to the filling material 51; 52 applied. This can be done by means of an engageable stop 59. Finally, the slides 54; 56 is opened and the blanket unit is vulcanized. This vulcanization can be carried out within the device 41, but also outside the device 41.

The FIGS. 9 and 10 show a particularly preferred manufacturing method for another blanket unit. This embodiment of a blanket unit makes it possible to close and reinforce a channel of a cylinder.

The filling compound 51; 52 extends here at a virtual extension V43 of the outside of the blanket 43 in the longitudinal direction, ie circumferential direction, of the blanket 43. In this case, the filling material 51; 52 both over an end 61; 62 and over both ends 61; 62 of the blanket 43 protrude in the longitudinal direction. In the radial direction, the filling compound 51; 52 at least partially beyond the virtual extension V43 of the outside of the blanket 43 survive ( 10 and 11 ).

This embodiment is achieved by the following manufacturing method. As already described, at least one end of the support plate 42 is bent. Subsequently, the blanket 43 is applied to the support plate 42. It is irrelevant whether the blanket 43 is already vulcanized or not. The sliders 54; 56 are then closed. The filling compound 51; 52 for closing and reinforcing a channel is now pressed or poured. Depending on how the slider 54; 56 are formed, a corresponding shape of the filling material 51; 52 reached. Thereafter, the filling compound 51; 52 dimensionally processed. Subsequently, as needed, the vulcanization process can take place inside or outside the device 41.

The two latter production methods thus differ in that in the embodiments according to the FIGS. 6 to 8 the filling material 51; 52 is disposed between the support plate 42 and the blanket 43, wherein the filling material 51; 52 is disposed first on the support plate 42 and then the blanket 43, while in the embodiments according to the FIGS. 9 to 11 the carrier plate 42 is connected to the blanket 43 and then the filling material 51; 52 is filled, wherein a radially arranged outside of the filling material 51; 52 is not occupied by the blanket 43.

As in the FIGS. 8 . 11 and 12 illustrated, the blanket unit at least one end with a greater thickness than the lying between the two ends region, so that the outer surface of the blanket unit in the region of this end in the radial direction at least partially beyond the virtual extension V43 the outside of the blanket 43, in particular is wedge-shaped. To thicken the end of the filling material 51; 52 arranged at the ends of the blanket 43. In the FIGS. 8 and 12 is a relining of the blanket to 43 recognize, in Fig. 11 a filling of the blanket 43 is shown.

This thickened end or both thickened ends are in on the blanket cylinder assembled state in the radial direction via a virtual extension of the subsequent blanket, ie the effective radius of the mounted blanket is greater in the region of the ends. The intervening areas are much larger (at least 10 times) than the area of the ends. The thickening in the circumferential direction preferably extends to less than 10 mm, in particular to less than 5 mm.

As a result, in the state attached to the blanket cylinder, a radius R11; R12 ( Fig. 12 ) of the cylinder based on the outside of the blanket 03 or based on the outside of the filling material 13; 14 at least in the region of one end of the printing blanket unit greater than a radius R03 of the cylinder relative to the outside of the blanket lying in the region between the two ends.

For all methods, the filling compound 13; 14; 29; 51; 52 is introduced in the flowable, deformable state, in each case at least one end of the two ends of the blanket unit. The filling compound 13; 14; 29; 51; 52 is in the longitudinal direction at least partially on a fold 08; 09; 27; 28; 48; 49 of the angled leg 04; 06; 21; 22; 44; 46 of the carrier plate 02; 18; Arranged 42 and projects beyond the fold 08; 09; 27; 28; 48; 49 in the circumferential direction addition. After application, the outside of the filling compound 13; 14; 29; 51; 52 are processed dimensionally stable. The filling compound 13; 14; 29; 51; 52 may preferably be integrally formed. The materials of printing blanket 03; 43 and filling material 13; 14; 29; 51; 52 may be the same or different.
