Definitions
- Laminates in particular mean plastic or plastic laminates or plastic-metal laminates, such as those used for the production of multilayers (printed circuits) and for plastic cards such as check cards. , ID or driving license cards can be used.
- Such a press is known from WO 03/064156 A1.
- the known press has two press plates which are movable relative to one another in order to exert a press pressure on a laminate located between them.
- the laminate can be fed as a tape or in individual sheets, it is placed on one or more prepreg tapes and fed to the press.
- One or more prepreg tapes are also placed on the multilayer and fed to the press.
- a copper foil is placed on the top and the bottom, which are laminated in the press using the prepreg strips.
- the aluminum foil serves as a conveyor belt and as an electrical resistance heater.
- the invention has for its object to improve a press of the type described above, in particular the electrical connection of the heating foil is to be improved.
- the press according to the invention has a heating film which is arranged firmly on a surface of the press plate facing the laminate and which does not move with the laminate.
- a heating foil can be provided on one or on both press plates.
- the heating foil is connected to an electrical power source and is supplied with current at least during the pressing. It acts as an electrical resistance heater and heats up the laminate during pressing.
- the heating foil does not necessarily have to be thin and flexible, it can also be comparatively thick and rigid, the use of a sheet as heating foil in the sense of the invention is conceivable.
- the invention has the advantage that the heating foil can be connected to the power source permanently and well, in particular with good electrical conductivity and with a low contact resistance, so that contact erosion is largely excluded. Another advantage is that such contact erosion, if it should occur, is not transported to the press surface because the heating foil is firmly attached to the press plate and does not move with the laminate.
- a preferred embodiment of the invention provides a steel foil as the heating foil, which has a pressing surface that is hard in comparison to, for example, copper or aluminum, which is regarded as an advantage for lamination. Another advantage of the heating foil is that it can be easily replaced if it is dirty, worn or damaged, so that a perfect pressing surface is available again.
- One embodiment of the invention provides an electrically non-conductive conveyor belt for transporting the laminate through the press.
- the conveyor belt is carried out between the press plates, it is located between the lower press plate and the laminate that lies on the conveyor belt.
- the conveyor belt is made of a material that does not melt at the laminating temperature but still has sufficient strength for its purpose and that does not stick to the laminate when laminating.
- the conveyor belt can adhere to the laminate after lamination, but it must be possible to remove it from the laminate without leaving any residue.
- the conveyor belt is, for example, a polyester film.
- a plastic copper foil can also be used as the conveyor belt, the copper foil being removable from the plastic foil.
- the copper foil is laminated to the laminate during lamination and forms an outer layer of the multilayer. The advantage of the conveyor belt is that it provides a clean and flawless surface for pressing the laminate.
- a further development of the invention provides that the conveyor belt is used as a disposable belt and is only carried out once by the press. This has the advantage that the conveyor belt is brand new when it gets into the press and comes into contact with the laminate. Waste due to contamination of the surface of the conveyor belt is avoided.
- the invention is explained in more detail below with reference to an embodiment shown in the drawing.
- the single figure shows a schematic representation of a press according to the invention in side view.
- the press 10 has a fixed lower press plate 12 and a movable upper press plate 14, which can be lowered onto the lower press plate 12 for pressing.
- a steel foil is stretched as a heating foil 16.
- the heating foils 16 are connected to electrical voltage sources 18 and act as resistance heaters.
- the press plates 12, 14 are electrically insulating or have an electrically non-conductive surface, at least in the area of the press surfaces.
- the press plates 12, 14 can for example consist of anodized aluminum.
- an upper and a lower conveyor belt 20 are made, which consist of an electrically non-conductive material, the melting or softening temperature of which is above a laminating temperature of the press 10.
- the conveyor belts 20 can be polyester films, for example.
- the conveyor belts 20 are unwound from supply rolls 22 and wound up on winding rolls 24 after they have passed through the press 10. The conveyor belts 20 thus arrive brand new in the press 10 and are used only once.
- a material to be laminated for example layers of a multilayer 26 to be laminated, is introduced between the conveyor belts 20.
- the multilayer 26 is transported with the conveyor belts 20 between the press plates 12, 14 by driving the winding rollers 24.
- the conveyor belts 20 are stopped and the press 10 is closed by lowering the upper press plate 14 onto the lower press plate 12.
- the heating foils 16 are energized and heat up due to their electrical resistance.
- the multilayer 26 is heated to a lamination temperature through the conveyor belts 20 and a pressure is applied to it by the pressure plates 12, 14. After the lamination temperature has been reached, the energization of the heating foils 16 is switched off.
- the press 10 remains closed until the multilayer 26 has cooled to such an extent that it can be removed without the risk that its layers move against one another or detach from one another.
- the press 10 is opened and the winding rollers 24 are driven, so that the conveyor belts 20 transport the laminated multilayer 26 out of the press 10.
