Abstract

1,269,542. Embossing. T.M.M. (RESEARCH) Ltd. 11 Nov., 1970 [22 Sept., 1969], No. 46585/69. Heading B6J. In a method of embossing film material by feeding a heated film over and in contact with a grooved surface, the film is moved away from the surface at a speed higher than that at which it is to the surface. The surface may comprise a grooved roller having a surface speed just exceeding the speed at which the film is fed to the grooved surface thereof. Alternatively the grooved surface may be stationary and situated downstream of an extrusion device producing the film. The film may be of polypropylene, polyethylene or nylon. The embasments may be such as to cause the film to split along the embossed lines.
