Auxiliary feed attachment for a circular knitting machine

摘要

A tubular knit fabric article having a two ply end portion that is confined to a reduced tubular size at the outer end thereof by an auxiliary yarn disposed between the plies in an unknit constricting loop and with the ends of the auxiliary yarn knit in the fabric of the plies. The constricting loop is formed by feeding the auxiliary yarn to the needle circle of a circular knitting machine during the knitting of a welt-like portion using an auxiliary yarn feeding attachment that first feeds the auxiliary yarn for knitting the leading end in the tubular fabric, then feeds the auxiliary yarn under tension in a non-knitting position at which the yarn is drawn by the previously knit leading end around the tubular fabric in a constricting loop or loops, and then cuts the trailing end of the auxiliary yarn, which is disposed in the needle circle for knitting in the tubular fabric.
