Abstract: A device for cutting and turning a piped opening in a cloth workpiece which includes a main piece of cloth and a cloth strip sewed to it. The workpiece has a slit, and corner cuts are formed at the slit ends by corner knives with the workpiece lying on a support plate. Turning tools are introduced into the slit at positions located spaced from the corner cuts. The turning tools are then moved apart toward positions located closer to the corner cuts and thereupon lowered, so as to turn the piped opening. Inserting devices may be provided for initially pushing at least part of the workpiece into the slit before being engaged by the turning tools. An orienting device furthermore may orient the workpiece at an acute angle or perpendicular to the support plate for being engaged by the turning tools.

Abstract: A folding stamp for folding sewing parts which are to be attached to a main sewing part, in a sewing system for making pockets in articles of clothing. The additional sewing parts, such as flaps or pocket-bag blanks, can be fed manually. This folding stamp has a fastening unit arranged on an upwardly and rearwardly extending extension formed on a vertical web. The fastening unit thereby extends above a resting surface on top of the web and in the direction toward the rear end of the folding stamp. The folding stamp is thereby arcuate or C-shaped in longitudinal cross-section, which gives it a compact construction and gives the operator an unimpeded view of the region in which he must feed the additional sewing parts.

Abstract: The invention relates to a method and an apparatus for the production of a coaxial tobacco or filter rod, a first production machine processing a strip-like first covering material and a stream of filling material to give a preformed rod which is deposited in a special magazine in order to be removed again therefrom in due course and supplied to a second production machine which brings the preformed rod together with a stream of filter or smoking material and a strip-like second covering material and processes it to form the coaxial tobacco or filter rod.

Abstract: A sewing device for producing piped openings such as pocket slashes, with or without a pocket flap. The sewing device includes a two-needle sewing machine having a vertically moveable center knife for cutting an opening to be piped, a cutting device including two vertically moveable angle cutting knives for performing gusset cuts, and a material transport device for receiving material to be sewn and transporting such material between the sewing machine and the cutting device. Also provided is a control system including a microprocessor for adjusting the operating positions of the various components to move the points of commencement of the parallel seams, the center knife, and the angle cutting knives, individually or jointly, forward or backward, to conveniently and selectively change these sewing parameters in response to the specific workpiece. In one embodiment, a common drive motor is provided for the two-needle sewing machine, the transport device, and the cutting device.
