摘要:
A piece of textile goods is selvedged along an edge extending between ends of the piece by gripping a strip of the piece offset from the edge and displacing it parallel to the edge at a constant travel speed such that successive portions of the edge pass through a plurality of folding stations followed by a sewing station. The edge is folded over as it passes through the folding stations and the folded-over edge is stitched together in the sewing station. The portions are gripped in each station upstream of the sewing station as they pass through. To eliminate an out-of-square condition the gripped portion is advanced when it is adjacent one end of the goods at a speed that is greater than the constant travel speed, the gripped portion is advanced when it is adjacent the other end of the goods at a speed which is less than the constant travel speed, and the gripped portion is advanced when it is offset the ends of the goods at a speed which is substantially equal to the constant travel speed.

A pile-detecting apparatus is used in a machine wherein a pile fabric is deflected over a smooth surface of a roll to detect the edge between the pile-free portion of the fabric and the portion with the pile, which edge runs parallel to the displacement direction of the fabric over the roll. The apparatus has a support plate, a frame carrying the plate, a plurality of rollers mounted on the frame and riding on the surface of the deflecting roll, and at least one light source on the plate for generating light beams and directing same tangentially of the surface. Respective detectors on the plate receive the respective light beams.

A succession of web workpieces are first positioned at a loading station one after the other flat on an upstream input conveyor and then are transported by the conveyor in a transport direction through a treatment station where the workpieces are acted upon to a downstream output table. The workpieces are then gripped one at a time, and then lifted off the output table and displaced laterally of the transport direction to a return conveyor extending in the transport direction. These workpieces are then moved by the return conveyor opposite the transport direction to the loading station.

A device for tensioning and aligning a fabric includes a support member to which a plurality of tensioning segments are connected such that each of the segments in automatically lifted when a longitudinal hem of the fabric passes thereunder. The support member is provided with a guide plate at each vertical end which guide plates face each other and project into associated slots provided at the vertical ends of the segments with a play so as to allow a limited vertical movement as well as a limited horizontal movement of the segments along the guide plates. Each of the segments has a main body which is provided with a finger-like step-shaped extension so as to define a projection facing the fabric and a space which embraces the respective edge of a nap zone with a certain clearance.

A device for applying fabric webs includes upper and lower runners each formed with a respective edge facing a pile edge of the web and provided with respective first, second and third segments which are differently shaped and provide aligning of the edge and a seam during hemming and sewing operations.

A crosscutting device for webs of material, particularly textile webs includes a web feed with a web buffer arranged on a common frame with the cutting station, a cutting station with a rotating disk cutter, driven transport nippers and a tray for stacking the cut material, the rotating disk cutter being automatically moved back and forth across the web by means of a disengageable belt in one of the operating modes and in a second operating mode the disk cutter being movable manually across the web and at the same time also in the running direction of the web.

A conveyor gripper for a substantially flat object, especially a textile web, has two gripping plates forming gripper tongs held in a gripping body. A pressing force which is constant over the entire length of the gripping plates is generated by at least one pressurizable air tube. A plurality of compressable springs distributed over the length of the gripping plates and can act against the pressing force of the air tubes. Also a plurality of safety straps can be located on the gripper body to prevent the spreading out of the gripper body.
摘要:
Via a textile guide system for flat textile goods, the textile goods are fed by a continuous conveyor to processing stations and the textile web is fed between conveyor elements of the continuous conveyor and a stationary support whereby means is provided to press the textile web against the stationary support and whereby each pressing member has a vertical guide means in which a housing-fixed holding pin engages and apart from the guide means at least one pressing spring means is provided whereby the noise formation is largely suppressed. The vertical guide means is close to the oncoming end of the pressing member approached by the conveyor and the pressing spring means is arranged close to the downstream end of the pressing means.

Pieces are cut off the end of a long web by first impaling the leading end of the web on a crosswise circulating needle bar that is then moved downstream from a cutting to a holding section. Then at the cutting station another such circulating needle bar and a noncirculating needle bar are poked through the web, with the noncirculating bar being downstream (relative to the displacement direction of the web) of the circulating bar. Then the web is cut across between the two upstream bars and the noncirculating bar and the downstream circulating bar are dropped down to transfer the piece thus cut from themselves to a transverse needle-chain conveyor. Then the circulating bar is moved back from the downstream holding station to the upstream cutting station while the second circulating bar pulls another piece of the web downstream across above the transverse conveyor.
摘要:
Process and apparatus for automatically producing a fabric with aligned nap zone and napless zone includes a conveyor along which the fabric is transported in such a manner that its nap zone is located at one side of a press pad and the napless zone is located under and at the other side of the press pad. A clamping device can be lowered on the napless zone to pull the latter transversely to the conveying direction of the fabric so that the edge of the nap zone is forced towards the press pad and to be aligned parallel thereto. Through cutting the napless zone in conveying direction after the nap zone is urged to lie against the press pad parallel to the edge of the nap zone an exact alignment of the napless zone to the nap zone is achieved.
