Abstract
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.
