To enhance printed products, lamination is to be carried out by a controllable pair of laminating rollers, rather than by the conventional method of calender rolling. To do this, the film is applied with relatively low contact-pressure roller pressure in a floating manner. The film can be fed to the laminating rollers without tension by means of a controllable applicator mechanism with a film tension regulating device. The processing rate and sheet length, for example, can be entered by computer so as to control the sequence of the feeder output and also the sequence of a wet cutting device via a suitable incremental-value transmitter from the main drive. Accordingly, processing rates of 60 to 100 meters per minute can easily be set. The quality remains good even at the highest speeds.
A process for the production of laminates comprising the steps of:
In a device for separating a laminate made from a web-shaped film coated with adhesive and from individual sheets joined by the coated film, wherein the laminate is guided past a cutting station from a laminating machine in a continuous manner, the improvement comprising that the cutting station has a cutting knife which moves along at the speed of the laminate, and computer, and a speed regulating drive of the cutting mechanism which is constructed as a thermal cutting knife with revolving knife mechanism and has a zero-position sensor in an upper deceleration or rest range.
In a device for producing a sequence of individual sheets on a sheet feed belt for a processing process, for example, for a laminating installation with a controllable sheet feeder, the improvement comprising that it is controllable by a computer which is functionally linked with an actual-value receiver for the processing rate, and with an incremental transmitter of the following processing installation, as well as a mechanically controllable sheet sequence generating device.
An installation for laminating and for the production of a laminate from a thin film and individual sheets, comprising:
A device for producing laminates made from a thin film and individual or continuous sheets, in which the laminate is connected by radiation-curable adhesive, comprising:
