Abstract

1,144,417. Coating apparatus. FARBENFABRIKEN BAYER A.G. 15 Nov., 1967 [16 Nov., 1966], No. 51908/67. Heading B2L. Foam-forming mixture is applied to a film on a moving support by a fan-shaped reciprocating jet directed parallel to the direction of movement of the support. A sheet 2, supported on an endless conveyor 1 and formed . with turned-up edges 3, is coated with a foam-forming mixture projected as a fan-shaped jet 4 directed in the direction of movement of the conveyor 1 by a nozzle 5 arranged on a mixing head 7 adapted to move to and from a rail 6 disposed at right angles to the direction of movement of conveyor 1. 'The arrangement is intended to prevent the mixture from being sprayed on to the inner surfaces of the edges 3. The nozzle may comprise either a slot arranged at right angles to the direction of movement of the mixing head, and at least one pair of apertures directed obliquely to each other in the direction of movement of the mixing head. The latter moves at a speed of 100 to 200 meters per minute. The jet encounters sheet 2 at a pressure of at least 0.1 kg. per square cm.
