Abstract
Fabric made up of a series of knitted collars, sleeve bands, bottom bands, plackets, or the like, intended for use on knitted sport shirts, blouses, and the like, and held together by a separator thread with a relatively high melting point is separated by means of gradually heating the fabric to near the melting point of the separator thread and then to the melting point while holding the fabric under tension.
Claims5
A method for fabricating and separating knit garment pieces such as collars, bands, plackets, and the like, comprising:
- (a) knitting a strip of fabric comprising a series of garment pieces having one edge of each connected to the edge of the next successive piece by a separator thread having a melting point substantially less than the melting point of the body threads from which the pieces are knit:
- (b) conveying said strip of fabric uncompressed on a belt conveyor and gradually heating the strip with heating means located above the conveyor while being conveyed through a first zone of extended travel to a temperature less than but near the melting point of the separator thread while maintaining the strip under tension whereby to soften and more fully expose the separator thread;
- (c) while maintaining the tension on said strip on said conveyor, heating the strip including the separator thread with heating means located above the conveyor to the melting point of the separator thread while being conveyed through a second zone of short travel forming an extension of said first zone to effect full separation of the pieces and to allow the residual separator thread to shrink within the fabric;
- and
- (d) separating any remaining body threads joining the pieces together to provide fully separated pieces for further processing.
