Abstract: A device for producing a seersucker fabric on a loom lengthens the effect or pile warp threads compared to the base warp threads at the binding point of the woven fabric. The device is arranged on the outlet side of the loom. Simultaneously, the effect or pile warp thread gang is relieved of tensile loads on the inlet side of the loom in such a manner that it will retreat or creep back to the pile warp beam as little as possible. A lengthening of 41% and more is achieved, compared to length additions in the prior art in the range of 30 to 32%. Additionally a very uniform seersucker fabric free of faults is produced.
Abstract: A gripper loom is equipped along its reed or slay beam with a plurality of compartments formed by separation walls extending in parallel to each other and in parallel to the lower shed forming warp threads which pass through these compartments. The upper edges of the separation walls are aligned with each other and with a guide surface of the gripper rods so that the upper edges form extension guide surfaces for the gripper rods. Thus, the lower shed forming warp threads do not interfere with the proper motion of the gripper rods.
Abstract: A tentering chain has a continuously adjustable chain pitch for the simultaneous biaxial treatment of film webs. Tenter bodies conventionally equipped with clamps or hooks for gripping an edge of the film web are carried by the tentering chain. Guide rails operate the tenter clamps. Neighboring tenter bodies are interconnected by chain links. Each chain link is connected by a hinging connection at each end to the respective tenter body. At least one of the two hinging connections of a chain link is adjustable by a hinging bolt having an eccentric section or sections and a circular section or sections. The adjustable eccentric hinging bolts are mounted for rotation in the tenter bodies and the eccentric section engages the respective end of the chain link. For this purpose the chain link has a bore in which the eccentric section is received.
