Abstract
The present invention relates to a continuous method and device for obtaining from a long length of tubular knitted element, a sleeve with a turned back edge. The method consists in guiding the knitting by way of a tubular guide, with one end of said element projecting from the said guide, in turning back said projecting part by means of air jets and lateral gripping tongs, and in pulling forward the whole knitted element and cutting across the said element with a knife. The invention finds a particular application in the production of garment elements or trimmings, such as wrist-bands for gloves, cuffs for sleeves or polar necks.
