Abstract:
A process for manufacturing in crochet galloon machines, ribbons of synthetic fabric provided with flexible hooks for quick-closing devices of the tear type comprising a previous step of knitting a ribbon (10) consisting of a plurality of parallel chains (5) interlaced with weft threads so as to form successive sequences of loops (7) therewith, which loops are substantially transverse to the extension direction of the chains (5) and emerge from the surface of the ribbon itself, wherein it comprises the following further steps:submitting said ribbon (10), after formation of said loops (7), to a heat treatment adapted to substantially stiffen the loops themselves so as to set their geometric shape,carrying out a cutting operation of said stiffened loops in order to obtain a length of hook-shaped thread (8) from each of them.
