Abstract
A method of manufacturing a fabric-covered article, preferably a belt buckle, and a method for trimming the excess fabric and backing sheet material from a fabric-covered article. Apparatus for manufacturing the fabric-covered article, preferably a belt buckle and for trimming the excess fabric material after the fabric has been glued to the backing sheet, with a buckle-shaped insert sandwiched therebetween.
Claims3
A mechanism for trimming excess material from a fabric-covered belt buckle or similar article having a three dimensional insert between layers of fabric comprising:
- (a) a substantially flat block having a flat working surface and an upwardly extending cutting edge substantially corresponding in size and shape to the size and shape of the trimmed fabric-covered belt buckle or article;
- (b) a positioning means defined as a ridge substantially conforming in size and shape to the edges defined by said insert, telescopically housed within the interior of said cutting edge and vertically reciprocal therein, said positioning means being spring-biased such that, in its unloaded state, the top edge of said ridge extends above said cutting edge, said ridge of said positioning means providing a positive locating and alignment mechanism for said fabric covered insert with respect to said cutting edge prior to trimming;
- (c) a top cutting backboard overlying said ridge and said cutting edge;
- and,
- (d) said positioning means having an overall height less than the height of said cutting edge such that downward pressure on said positioning means transmitted through said cutting backboard causes said top edge of said ridge to retract beneath said top edge of said cutting edge such that said cutting edge contacts said top cutting backboard to effectuate trimming of said excess material.
