It is described a process for manufacturing in crochet galloon machines, ribbons of synthetic fabric provided with flexible hooks for quick-closing devices of the tear type, which process comprises a previous step of knitting a ribbon in which successive sequences of loops are formed. The ribbon is then submitted to a heat treatment adapted to substantially stiffen said loops previously shaped in an angle-bent conformation. Then a cutting operation is carried out on the stiffened loops so as to obtain one hook from each of them. A crochet galloon machine is also provided for forming said ribbons of synthetic fabric, said machine comprising a plurality of shaping elements adapted to form successive sequences of loops with the weft threads, a heat-treatment unit for setting the geometric shape of the loops, and a cutting device intended for cutting off the stiffened loops so as to obtain one hook from each of them.
