Definitions

  • the present invention relates to a laminating method and an apparatus for carrying out the same.
  • the invention relates to a method and an apparatus for coating a board with a layer of metal, which board is provided with an elongate groove, the layer of metal being attached to the board and laid in the groove.
  • Woodfibre boards with grooves for the installation heating cables or pipes for water- borne heat are available on the market today.
  • the boards may be made of a porous woodfibre material in order to provide good insulation and to have a sound proofing effect, especially for damping the sound of footsteps when they constitute a part of a floor structure. Boards of this type are widely used in the building industry, and the market is growing.
  • fibre board with grooves which preferably may be arranged in the longitudinal direction of the board, transverse to the longitudinal direction of the board, or may comprise grooves in different directions, where the board is coated with metal. Aluminium is for many uses, especially for building purposes, preferred as metal for board coating.
  • Metal coating of boards with grooves in continuous production has been found to pose many challenges, both as regards obtaining a favourable groove shape after the metal coating which makes it practically possible to install heating cable or pipes in the grooves and to ensure that they remain in place after installation, and as regards producing coated boards with the metal coating inserted in the grooves with good production output and uniform, predictable quality.
  • the present invention provides an apparatus for coating a slotted or grooved board with a sheet laminate continuously both in elongate slots or grooves and on the surfaces of the board between the slots or grooves, characterised by the features set forth in attached claim 1.
  • inventive apparatus for coating a slotted or grooved woodfibre board with a sheet laminate continuously both in elongate slots or grooves in the board and on the surfaces of the board between the slots or grooves are set forth in attached claims 2 to 18 inclusive.
  • the present invention further provides a method for coating a slotted or grooved woodfibre board with a sheet laminate continuously both in elongate slots or grooves in the board and on the surfaces of the board between the slots or grooves, characterised by the features set forth in attached claim 19.

  • Figures 3b and 3 c show in section and partly dimensioned, the exemplary embodiment of the elongate pressure projection illustrated in Figure 3a;
  • Figure 4a is a sectional view of the positioning of a pressure roller with projections, board with grooves and sheet laminating material in a first phase during continuous production of metal-coated board;
  • Figure 4b is a sectional view of the positioning of a pressure roller with projections, a board with grooves and sheet laminating material in a second phase during continuous production of metal-coated board.
  • a metal-coated board product preferably consisting of Al foil
  • a sheet laminating material 50 on a roll 800 mm wide which comprises 40 micron (110g/m2) aluminium, a glass fibre net reinforcement (19g/m2) and LDPE plastic for laminating the glassf ⁇ bre net to the aluminium (50g/m2)
  • the board is produced and supplied typically by a board manufacturer according to set measurements and with ready milled grooves or slots in the full longitudinal direction of the board.
  • the board also comprises grooves located along the edge of the board but at a slight distance from the board edge, which are referred to herein as side grooves.
  • Side groove recesses may be arranged along one or more of the board edges.
  • the ready milled grooves into which the metal coating is to be guided may be dimensioned to a width of 4 mm +/- 0.1 and a depth of 5 mm +0/-0.5.
  • the side grooves (for overlay of metal coating which can be perforated) are preferably dimensioned to a width of 15 mm and a depth of 5 mm +0/-0.5.
  • a second preferred dimension for a porous woodfibre 40 board that can be produced by the inventive apparatus and/or method, which board is especially suitable as a footstep sound damping floor structure element for supporting a heating cable or a pipe for transport of a heating medium, the heating medium preferably being hot water, is 790x1183x12 mm (LxBxH).
  • the invention is adapted to produce a metal-coated board of the aforementioned types where the grooves into which the metal foil is pushed are dimensioned to a width of 4 mm +/-0.1 and a depth of 5 mm +0.2/-0.3.
  • the tolerances of this variant may provide a more optimal performance in connection with the use of the inventive apparatus and method.
  • An aluminium foil that is provided with a reinforcing layer of a fibre net, or similar reinforcement, in combination with a meltable plastic material, such as a polyethylene plastic material, is preferably used for the production of the metal-coated board according to the inventive apparatus and method.
  • the inventive production apparatus preferably makes use of a plastic material which is included as a component in a reinforcing net for an aluminium foil. With the inventive apparatus or method, this plastic is melted "again", that is to say after the metal foil has been placed against the board, thus forming a connection between the woodfibre board and the aluminium foil.
  • the boards are fed into the machine, preferably fixed butt-to butt.
  • the Al foil is pressed and formed using a roller provided with “rulers”, and is thus laid on the board, and in the grooves with the aid of the "rulers”.
  • a "heated strip” is then used to melt the plastic so that the reinforced Al foil bonds to and is attached to the board in the areas between the grooves.
  • the boards are then separated again and trimmed according to need, and placed on pallets for further transport or storage.
  • the new automatic line that is constructed according to the invention will consist of a laminating machine as described herein, preferably combined with processing equipment for milling the grooves in the board. It has been found that the tolerance limits that a woodfibre board with pre-milled grooves can have are large, and that machining of the grooves immediately prior to the laminating machine will be extremely favourable for production output and product quality.
  • the actual roller that shapes the aluminium in the grooves is designed so that it has a diameter which enables it to hold the foil in place before the "pressure blade” (also referred to herein as “ruler”, “die” or “projection”) guides and presses or pushes the metal foil into the groove.
  • the inventive design of the roller and "pressure blade” results in the foil being given a favourable filling material form, which will be explained below, and is such that the foil is held properly in place and is not pulled of from the last formed groove until the following attachment process has been completed.
  • the diameter of the roller is adapted to a total of six grooves, wherein the said “rulers”, also referred to here as “pressure blades”, are to be positioned so that the "rulers” by virtue of their spacing on the roller match the distribution of the grooves in the board, i.e., the spaces between the actual grooves in the board.
  • Figures 2a, 2b and 2c for an example of a roller with six grooves.
  • the appended illustrations also show arrangements for the use of fixing screws to hold "pressures blades" in place in respective grooves.
  • the diameter of the roller will then 187.8 millimetres for six "rulers".
  • the length of the roller is 800 millimetres, as adapted to one of the dimensions (length dimension) of the board being 790 millimetres, as given above for the currently preferred dimensions of the board for metal coating.
  • Six grooves of a depth of 15 mm + 1 and width of 4 mm + 0.1 are milled out in the roller. The depth tolerance allows adjustments by inserting shims in the groove so that the "ruler" will project the correct distance from the roller surface.
  • rulers which preferably are formed of a teflon material, or at least of a suitable material having teflon-like qualities, which are configured with a “tooth shape” in order to press the foil down in the groove without it being brought into permanent contact with the edges of the groove in the board.
  • a preferred "tooth shape” can be seen from Figures 3b and 3c.
  • the foil When placing the metal foil in a groove, it is preferable to push the foil to a sufficient depth in the groove to have a filling material form so that a metal layer is formed in the groove which essentially follows the side edges of the groove, and where the metal layer does not come into contact with the bottom of the groove. It is especially preferable that the inventive apparatus and method are so adapted that the foil is placed in the groove in the board at a distance of about 0.5 millimetres from the bottom of the groove. To obtain such a filling material form of the metal layer in the groove, the "ruler" should be placed in the roller so that it projects at a distance that corresponds to the depth of the groove minus about 0.5 millimetres.
  • the groove is made having a depth that is equal to the groove width with an addition that is in the range of 0.5 to 1.0 millimetres.
  • a frequently used heating cable has a diameter of about 4 millimetres
  • a suitable metal-coated board is produced by means of the invention from a board having a groove width of 4 millimetres and a groove depth of 5 millimetres, the "rulers" in the roller being mounted so that the point on the rulers that projects farthest from the roller is at a distance from the roller surface that is from about 4.3 millimetres to about 4.5 millimetres.
  • the preferred distance from the roller surface to the point on the rulers that projects farthest from the roller is about 4.5 millimetres, to ensure a distance between the foil in the groove and the groove bottom and at the same time allow for variations in the depth of the groove.
  • the heated bar lies as close as possible to the outer edge of the roller, to ensure that the melting process of the plastic on the Al foil is commenced as quickly as possible after the forming and pressing of the Al foil onto the porous board.
  • the actual heating zone is adapted to the aforementioned measurements 100 x 800 mm, and controlled by temperature adjustment.
  • the temperature is preferably about 220 degrees C with the materials and dimensions that are described herein. However, the temperature can be adjusted somewhat according to the rate of advancement of the production line, and is adjusted to ensure that optimum adhesion between the Al foil and the porous board is obtained. More specifically, the best adhesion is obtained when the plastic has been melted and has penetrated into the porous board.
  • the heated element is mounted floating to allow optimum contact between the element and board to be obtained at all times. With 25 g/m2 PE plastic, operations take place at a temperature of about 220 degrees C and with 50 g/m2 PE plastic, operations take place at a temperature of about 280 degrees C. This is done with a feed rate of the boards of 1.1 m/minute. By increasing the width of the heated bar to 200 mm, it is possible to operate at an advancement rate for the boards of about 2.2 m/minutes at the same temperatures.
  • the Al foil is cooled so that it does not incorporate stresses into the board which may result in a bending of the board.
  • the Al foil is cooled rapidly, and the melted plastic that functions as bonding will be cooled somewhat later and retain its plasticity. A possible bending of the board which may otherwise occur as a result of heating/cooling of Al foil is thus avoided.
  • An example of a production machine which will be explained below with reference to Figure 1, comprises a roller conveyor 1, which is preferably a belt conveyor that is 800 mm wide.
  • the conveyor is a standard belt conveyor, which has frequency-controlled operation for conveying boards through a laminating zone, a supporting structure 2 which forms a machine frame on which the belt conveyor and laminating roller, heated bar and cooling zone are mounted, step bearings, four in number, for example of the type SKF SY 25TF, on two of which the actual forming roller is mounted.
  • These bearings can be adjusted so that it is possible to ensure the parallelism between the rulers mounted in the roller and grooves in the board.
  • the two other step bearings are for the mounting of the heated bar.
  • the heated bar can be placed up or down towards the laminated board by means of a handle (crank handle) as shown at 12.
  • the production machine further comprises a heating station 4, preferably formed of a heated bar of aluminium 800 mm long and 100 mm wide having affixed thereto a plurality of heating elements.
  • the heated bar is mounted floating so that it rests against the aluminium foil in such manner that it is pressed down against the board whilst the heat melts the PE plastic on the rear side of the aluminium so that it forms a laminating layer between the board and the Al foil.
  • This heated bar is placed as close to the pressure roller as possible to prevent any deformation of the Al foil after it has been shaped to the board.
  • a cooling plate of steel with air nozzles located immediately after the heated bar.
  • the production machine further comprises a threaded bar 5 for adjusting perforation wheels 9.
  • Four nuts 6, preferably locking nuts, are arranged for locking the perforation wheel mounting bracket.
  • Two wheel mounts 7 form mounting brackets for the perforating wheels.
  • Four washers 8 are used for fastening the perforation wheels.
  • Two perforation wheels 9 for perforating 15 mm longitudinal grooves in the aluminium on the laminating sheet to mark and prepare for placement of the supply cable in the finished board. The purpose of this perforation is that the consumer should have it to cut along when there is a need to use this groove for the turning/introduction of electric cable during mounting.
  • These perforating wheels are round blades in which notches have been cut.
  • two Allen screws 10 and two nuts 11 are included for mounting the perforating wheels.
  • the production machine further comprises a lifting device 12 for the heating station 4.
  • Two spherical supports 13 and two swivel flanges 14 are included for suspension of pressure cylinders.
  • Two cylinders for example of the type 1 633 70 DNC 50 Festo, to adjust pressure on the forming roller and to be able to lift the roller for aligning roller/board/aluminium.
  • a roller pressure is established against the foil and board whereby a very good result is achieved when forming and coating a porous woodfibre board of the previously mentioned type.
  • two flex connections 16 are used, for example of the type 6142 FK M 16x1 5 Festo.
  • the circumference of the roller is, as indicated above, preferably equal to the board width, and thus for a preferred board dimension the circumference is 590 mm.
  • the roller weighs 92.4 kg, which is preferred in order to press the boards down against the belt 1 to ensure good quality and advancement through the laminating station.
  • the aluminium foil is preferably supplied from a roll.
  • Two roll blocks 19 are preferably made of nylon to fit into the sleeve on the aluminium roll. This is to ensure correct mounting of the roll on a stand.
  • Two bearings 20, for example, of the type 6006 2Z SKF, are used to ensure that the Al roll runs easily on the suspension roller 24.
  • Two Seger rings 21 are used for the locking of bearing 20.
  • Two spacer sleeves 22 are used for the correct positioning of the roll of aluminium laminating material in relation to the feed-in of boards.
  • Two stop rings 23 are used to prevent the Al roll from moving on the suspension roller 24.
  • a blank roller 23 forms the roller for suspension of the alurninium roll.
  • guide rollers are mounted for the aluminium foil, so that it does not wander in relation to the boards that are fed in.
