Process for the continuous production of slip * or the like. Priority: October 26, 1967 - Sr. 43 758/67 - ÖroBbritamils

The invention relates to garments and, more particularly, to a continuous one Process for the production of panties, which were previously produced by semi-automatic processes.

The inventive method for continuous production of briefs from substantially rectangular pieces of goods consists essentially in the fact that parts from opposite sides of each Piece of goods cut out for the formation of thigh-shaped cattle be, an elastic strip under tension on each »leg shape edge and at each of the opposite ends of the commodity fuck is attached, then with each elastic strip held in a condition sufficiently stretched to be substantial Wrinkles in the goods adjacent to the elastic strips

Under the name "Slips" are not only those Daeen-Unter-. bokleidungsstücko to understand, also known as "DaraenhOschen" find, but also baby panties and similar items with elastic Stripes on the hips and on the leg openings.

The term "item ^{11 of} goods includes pieces of textile goods, such as knitted goods, woven goods or nonwovens, which are made from natural or synthetic fibers or mixtures thereof, or pieces of foils made of plastics or cellulose-containing materials that are either smooth or perforated or, in a sense, textile Goods are embossed.

The textile goods preferably consist of stretch goods, which Made from stretch yarns, which give the goods a considerable amount Give elasticity and make briefs for a big one Range of sizes can be made without the need is to change the basic unstretched size of the garment »This increases the number of interchangeable machine parts reduced, which is required for the entire size range of the panties are.

For cutting out the parts from the piece of goods to form the leg edges and for the process of fastening the elastic Strips by sewing or other means on the bar if shape edges and at the ends, the item of goods can be useful be clamped in a flat state between two plates so that the edge parts of the VJaronstücks on the periphery of the plates exposed. The cutting out of each part can be done by shaped guillotine-like knives, but is expedient by a knife, which is carried as additional front equipment by a movable threading apparatus, which is carried by a template or by some other mechanism, ling a certain path and attaching the elastic strip attaches to the newly formed leg shape edge. In similar catfish can a movable thread sewing apparatus can be used, an elastic Sew on strips at each end of the piece of fabric. The end can expediently be an elastic one immediately before attaching it Strip are cut, which cutting by means of a knife happens, which is carried as additional front equipment on the Fadennäliapparat.
