Abstract

1,220,232. Laminating plastics foam materials. RUDOLPH KOEPP & CO. CHEMISCHE FABRIK A.G. 4 Jan., 1968 [9 Jan., 1967], No. 642/68. Heading B5N. The surface of a web of polyurethane foam is rendered tacky by means of a number of spaced infra-red radiators and is then laminated to another web of the same or different material. The infra-red radiators are preferably electrically heated but may be heated by gas or oil burners and are arranged to extend across. and be very close to, or even in contact with, the plastics web, or each may be positioned along one focus of a part-elliptical reflector in which case the plastics web passes through, or very close to, the other focus. The output of the heaters is preferably adjustable by a control unit, and each heater may be sub-divided into a number of separate sections. The process is said to be applicable to the lamination of polyether-based as well as polyester-based polyurethane foams.
