An installation for linear treatment, such as the edging of textile pieces. It comprises a sewing machine, equipped with a feed dog/presser foot system, a work table which supports the piece during edging, a detection device and two recentering means controlled together or independently of each other by the instructions given by the detection device. The two recentering means consist, on the one hand, of an active guide placed immediately in front of the presser foot and ensuring displacement of that part of the piece located near the presser foot, substantially transversely with respect to the line of stitching, and, on the other hand, of a mobile support placed upstream of the active guide presenting a mobile flat surface, on the same plane as the work table.

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.
