Abstract: With a method for completely automatic products of fitted sheets, elastic bands are sewn into or onto the cut edges (transverse edges), and the lengths of the elastic bands correspond approximately to the widths of the pieces of fabric. Then the widths of the pieces of fabric are measured and, dependent upon the results of this measurement, a piece of fabric is positioned in the middle or symmetrically in relation to the sewing needles of four sewing devices for formation of the corner seams, and the needles are provided in pairs facing each cut edge (transverse edge) of a piece of fabric at a corner processing station. Thereafter, the piece of fabric is hemmed in the corner of processing station parallel to its cut edges (transverse edges) and the hems of the piece of fabric are fixed.

Abstract: Apparatus and method of positioning and holding a thread chain for sewing onto successively fed workpieces, a thread chain which had been sewn beyond the rear edge of a workpiece and had been cut off flush with the rear edge of the workpiece, is sucked into the suction aperture of a suction tube. The suction tube is movable in a path parallel to the stitch plate of the sewing machine first in a catch position behind the needle and then the tube is moved into a delivery position before the needle aligned with a seam line (N). The chain is clamped there under a tensile stress in such a way that complete inclusion of the thread chain into the next following seam is possible. The suction tube extends parallel to the stitch plate and has a suction aperture into which the severed thread chain is sucked. The tube is moved to a delivery position in which the thread chain is pressed against an elastic abutment.

Abstract: A device for straightening a distorted strip article, particularly a textile strip having a marking thread or the like, and for cutting along a stitch or print line of the strip article. A plurality of movable straightening elements are arranged transverse to the length of the strip article and are movable into engagement with the strip and adjustable by a transport device in the longitudinal direction of the strip article. The straightening elements 18 are movable longitudinally and into engagement with the strip article independently of each other. A sensor device controls the movement of the straightening elements in response to control signals produced by the marking thread. The transport device is disposed transversely to the length of the strip article in the area of the marking thread.
