Abstract
An arrangement for producing a pantyhose from prefabricated hose-shaped individual parts has at least one template movable in working stations and composed of two tensioning arms for pulling corresponding prefabricated pantyhose parts of a pantyhose, the tensioning arms being movable parallel to one another and arranged on supporting arms, a cutting device defining a cutting plate, the supporting arms being mirror-symmetrical relative to the cutting plane of the cutting device, the supporting arms of the template being immovable relative to one another, bent in a plane of the tensioning arms in a U-shaped manner, and provided with driveable endless transporting belts.
Claims11
An arrangement for producing a pantyhose from prefabricated hose-shaped individual parts, comprising a cutting device defining a cutting plane;
- at least one template movable in work stations and having two tensioning frames for pulling corresponding prefabricated pantyhose parts of a pantyhose, said tensioning frames being movable parallel to one another and each being composed of two supporting arms which are mirror-symmetrical relative to said cutting plane of said cutting device, said supporting arms being immovable relative to one another, bent in a plane of said tensioning frames in a U-shaped manner, and supporting driveable endless transporting belts operative for pulling the pantyhose parts on said tensioning frames and for bringing and holding the latter on said tensioning frames in a desired position.
A method for producing a pantyhose from two prefabricated hose-shaped pantyhose parts, comprising the steps of placing one pantyhose part on ends of a supporting arm pair of a first tensioning frame which are close to a cutting plane and pulling point-by-point to a predetermined orientation position by means of transporting belts of said supporting arms;
- repeating the preceding step on a second tensioning frame and pulling a second pantyhose part with orientation of an initial portion of the pantyhose part of the second pantyhose part with an initial portion of said first mentioned pantyhose part;
- moving one of a template and a cutting device until the cutting device is located in a cutting plane between curves of the four supporting arms;
- transporting both pantyhose parts by synchronous driving of all transporting belts through a region of the cutting device with separation of the both pantyhose part hoses at opposite locations of both tensioning frames, and simultaneously lifting both pantyhose parts in their uncut region by lifting bars at opposite sides of both tensioning frames;
- moving formed cutting edges by the transporting belts over the curvature in outer legs of the supporting arms over a desired length;
- paired sewing of freely located cutting edges which are wound during bending in both pantyhose parts in at least one sewing station;
- back transporting the sewn pantyhose parts of the pantyhose from outer legs of the supporting arms by a direction reverse of a transporting belt drive and removing the finished pantyhose from the template.
An arrangement for producing a pantyhose from prefabricated hose-shaped individual parts, comprising a cutting device defining a cutting plane;
- at least one template moveable in working stations and having two tensioning frames for pulling corresponding prefabricated pantyhose parts of a pantyhose, said tensioning frame being movable parallel to one another and each being composed of two supporting arms which are mirror-symmetrical relative to said cutting plane of said cutting device, said supporting arms being immovable relative to one another, bent in a plane of said tensioning frames in a U-shaped manner, and supporting drivable endless transporting belts, said supporting arms having guiding paths;
- and means forming sliding surfaces located between said tensioning frames and extending parallel to said tensioning frames of said template, said endless transporting belts extending in said guiding paths of said supporting arms partially outwardly and having a driver edge extending opposite to said sliding surface for free running on said sliding surfaces.
An arrangement for producing a pantyhose from prefabricated hose-shaped individual parts, comprising a cutting device defining a cutting plane;
- at least one template moveable in working stations and having two tensioning frames for pulling corresponding prefabricated pantyhose parts of a pantyhose, said tensioning frames being movable parallel to one another and each being composed of two supporting arms which are mirror-symmetrical relative to said cutting plane of said cutting device, said supporting arms being immovable relative to one another, bent in a plane of said tensioning frames in a U-shaped manner, and supporting drivable endless transporting belts, each of said supporting arms having an outer free end and a curved part, each of said supporting arms having at least one lifting bar which extends from said outer free end and to the region of said curved part.
An arrangement for producing a pantyhose from prefabricated hose-shaped individual parts, comprising a cutting device defining a cutting plane;
- at least one template moveable in working stations and having two tensioning frames for pulling corresponding prefabricated pantyhose parts of a pantyhose, said tensioning frames being movable parallel to one another and each being composed of two supporting arms which are mirror-symmetrical relative to said cutting plane of said cutting device, said supporting arms being immovable relative to one another, bent in a plane of said tensioning frames in a U-shaped manner, and supporting drivable endless transporting belts having guides;
- means forming sliding surfaces, said supporting arms having an electromagnetically actuated braking mechanism which is coupled with said guides of said transporting belts and has a braking plate cooperating with a respective one of said sliding surfaces.
