Title:
DEVICE FOR LAMINATING A LAYERED STRUCTURE CONSISTING OF AT LEAST TWO PLASTIC STRIPS IN SECTIONS
Document Type and Number:
WIPO Patent Application WO2001021401
Kind Code:
A3
Abstract:
The invention relates to a device for laminating a layered structure (1), consisting of at least two plastic strips in sections, comprising successive panels with designs, for producing plastic cards along a conveyor path. Said device comprises heating and cooling devices (8, 9, 10, 11) which are positioned one behind the other and consist of individual compression elements, located on a common support (14), whose temperature can be controlled and which accommodate a whole number of panels and a drive unit which displaces opposing compression belts (2, 3) which can be driven intermittently in a direction of transport and between which the plastic strips can be displaced in sections through the heating and cooling devices. The aim of the invention is to provide a device which permits the production of plastic cards with a higher laminate quality. To this end, the compression elements are mounted so that they can be displaced in the direction of the conveyer path against a restoring force which acts upon their initial position.
