Abstract

1437538 Moulding foam plastics articles SCHOLL (UK) Ltd 19 July 1973 [5 Aug 1972] 34413/73 Heading B5A Apparatus for the continuous production of annular foamed plastics articles having an adhesive layer thereon, e.g. corn plasters, comprises an endless linked moulding belt 1 having female mouldings with upwardly directed cutting edges 10, 11; a spray gun 2 for filling the moulds; rollers 5 and a belt 3 for maintaining the foam under pressure as it expands and sets and also for facilitating bonding of an adhesive layer, carried by a silicone paper 4, to the material in the moulds; and rollers 9, having alternately concave and convex peripheral profiles, which co-operate with the cutting edges to separate the foamed moulding with their adhesive layer from the remainder of the foamed material. The remainder of the foamed material adheres to the silicone paper 4 and is removed from the belt 1 by winding on to a roller 12. The central sections 16 are removed from the mouldings by means of rollers 14 carrying pins 15 (Fig. 4) which press on to the sections 16 to cause their adherence to a removing band 20.
