In accordance with the present invention, there is provided an improved, simulated tufted cushion and method of making the same which involves simultaneously forming the tufts with simulated buttons and creases between tufts in a single operation in a heated press.
Claims4
An improvement in the method of making a simulated tufted cushion, which comprises:
- (a) forming discrete spaced openings extending through a foam rubber pad;
- (b) placing said pad on a lower sheet of plastic material, said sheet being disposed so as to have its entire upper surface in a single horizontal plane such that said extended openings remain available for filling;
- (c) substantially filling said openings from said horizontal plane upwardly with discrete plugs of fusible material;
- (d) placing an upper sheet of plastic material over said pad;
- (e) applying pressure selectively to said upper sheet so as to draw the upper sheet down into the openings containing said plugs of material, thereby to give the appearance of tufts;
- (f) heating selectively in at least said openings so as to fuse both of said sheets to the fusible material;
- and
- (g) providing tooling in the form of a grid with spaced hollow cylinders for insertion into said openings, said cylinders being connected by coordinate bars.
