Abstract: A needle guide integrated in a thread cutter of a sewing machine installed with a hook operating about a horizontal axis and a feeding mechanism generating a relative movement as a feed motion between a workpiece and stitch former. The needle guiding element is incorporated with the thread catcher receiving member and alternately moved into operation by the thread cutter actuator. Adjustors are provided to position the needle guide with respect to the needle.

Abstract: In an automatic sewing device for sewing together tubular workpieces such as sleeves, and pocket-shaped workpieces, such as cuffs, there are provided an inner clamp, a central clamp and an outer clamp. These clamps are associated with an inner sleeve clamp and an outer sleeve clamp, the latter being associated with a folding device for gathering up a material fullness of the tubular workpiece. Devices are also provided for opening the pocket-shaped workpiece in order that the border of the tubular workpiece may be inserted and positioned. The associated sewing machine can be moved in a straight line relative to the parts described. A part of the border of the tubular workpiece is positioned in the pocket-shaped workpiece and sewn to the latter by means of a straight-line seam. Subsequently, the clamping in this area is released and the positioning of the border of the tubular workpiece in the pocket-shaped workpiece is carried out and clamping is effected.

Abstract: In order to overcome especially large areas of obstacle between a carrier plate for a workpiece to be sewn and a tubular stud arranged at the underarm of a sewing head, the underarm is tiltably arranged as to be swung downwards from its working position. The axle about which the tilting of the underarm is carried out, is located in the area of the standard of the sewing head. Additionally the upper arm of the sewing head can be tilted upwards about the same axle. Separate individual tilt drives are provided for the underarm and the upper arm.

Abstract: A workpiece holder for sewing the tip areas of neckties comprises a lower plate and a central folding device between which a lining cut and a necktie material cut are arranged. The center folding device has folding plates which can be displaced transversely with respect to the longitudinal direction and which, when moving together, draw in the material fullness in the necktie cut and gather it in a central fold. Lateral seams are sewn after the sewing of outer seams in the tip area of the cuts.

Abstract: A workpiece clamp of sewing devices for sewing the marginal zones of a lining cut and a necktie cut in the area of the tip and the lateral corners of a necktie. The clamp is equipped with three clamping plates hingedly connected to each other, for clampably receiving the lining cut and the necktie cut between the clamping plates. The intermediate clamping plate is provided, at the surface directed to the necktie cut, with central folding web and lateral webs for forming a center fold and lateral folds. The upper clamping plate is provided with folding blades for folding and holding down the lateral folds in coaction with the clamping plates for clamping the workpieces to be stitched together.

Abstract: A template follower mechanism for use in automatic sewing machines in which a driven pinion means is borne against a template consisting of at least two gear racks slidable against one another in two planes. The pinion means consists of a first driven pinion capable of meshing with the teeth of one of said gear racks, and a second pinion coaxial with the first pinion, capable of meshing with the other gear rack. Means for arresting and resetting the second pinion in a normal position are provided. The teeth of the second pinion are in alignment with the teeth of the first pinion. Stop means for limiting the rotary motion of the second gear rack about one tooth pitch, one half in clockwise direction and one half in counter-clock direction relating to the normal position.
