Abstract (en)
[origin: DE19743611A1] To recover waste weft material from a catch selvage, sorted according to weft types, the full-cross leno is twisted out after the catch selvage has been cut from the woven fabric. The weft ends and the leno yarns are taken off separately. In an Independent claim, the apparatus has a control (8) to take off the material. A unit (5) to twist out the full-cross leno (1a) is on a linear extension of the catch selvage (1). A takeoff unit (6) is between the twisting unit (5) and the catch selvage (1), and a takeoff (7) leads the leno yarns (4) away. Preferred Features:- The working stages are effected by units with electrical controls. The twisting out of the full-cross leno is synchronized or is asynchronous with its formation, using an electrically controlled untwisting mechanism, with reversing rotation. The leno yarns are taken off by an electrically controlled takeoff. The weft ends are separated, and collected separately according to the weft types, and the leno yarns are collected separately. The wefts are collected separately, by type, by an electrically controlled waste removal system or by a common electrical drive, operating according to the sequence of weft insertions during fabric weaving, and the weft selection program. The unit (5) to twist out the full-cross leno (1a) has a rotating body (5a) to take the leno yarns (4), with reversible rotation. The rotary drive (5b) for the rotating body (5a) is an external electric motor. Alternatively the rotating body (5a) is the rotor of an electrically controlled setting motor. The weft ends (3a) are extracted (6a) as they move past the cleaning point, to be taken to at least one collection point (6b). The takeoff (7), for the leno yarns (4), has a pair of rollers (7a,7b) with at least one powered roller (7a) as the loom fabric take-in roller with the idle roller (7b) pressed against it. The leno yarn (4) takeoff (7) can also be a pair of rotated bobbins.
