ABSTRACT:
A method and relative equipment, applicable to a knitting machine for the production of collars and similar articles, for restraining, during knitting, the terminal portions of cut thread (12, 13) protruding from the edge (5) of said collars by inserting them inside the courses of stitches which compose them. The means for inserting (16) said thread ends (12, 13) between two successive courses of stitches (2,3 and 3,4) while knitting, comprise at least one nozzle (27, 37) producing a fluid current(22, 32). One of the nozzles (37) may be able to rotate from a first direction (A) of catching the end portion of thread to a second direction (B) aligned with the courses of stitches during the knitting process. Means for inserting can also comprise a first nozzle (27) producing a first jet of fluid (22) for catching the thread end and a second nozzle (37) producing a second jet of fluid (32) for inserting it between two courses of stitches. The restraint of the end portions of thread (12, 13) is carried out automatically while knitting, with considerable advantage compared to manual restraining as well as mechanical inserting, thanks to the precision of fluid jets (22, 32) which are preferably of air or water.
