  • Patent number: 6041989
    Abstract: An apparatus for producing high quality products of cloth strip by the improvement of working efficiency and the equalization of treatment conditions, wherein the cloth strip (2) is subjected to a predetermined treatment while passing through one treatment zone (3) along a spiral path. A plurality of metallic surface rollers (5-2 to 5-4), surfaces of which are formed with metal, are used as at least part of conveying rollers consisting of metallic rollers (5-2 to 5-4) for guiding the cloth strip (2), provided in at least one of entrance and exit parts for the introduction/withdrawal of cloth strip (2) to the treatment zone (3). The metallic surface rollers (5-2 through 5-4) are arranged in a non-contacted state with each other and positively driven to rotate via a suitable drive mechanism (6).

  • Patent number: 5749210
    Abstract: A creel 1 with twisting devices is capable of directly supplying twisted yarns from bobbins carrying non-twisted yarns to a loom or a warper, and of producing not only normal fabric but also a fabric having a low weft density woven at a higher rate or a fabric using hard-twist yarns as warps. A plurality of rotatable spindles 8, each carrying a bobbin 3 on which a non-twisted yarn 2 is wound, are arranged on a frame 18. The yarns 2 withdrawn from the bobbins 3 on the spindles 8 are twisted and arranged to form a yarn sheet 19. The spindles 8 are rotatably secured via bearings to the frame 18 of the creel 1 at the center of a rotary shaft section 8' which is arranged in a horizontal direction. On both ends of the rotary shaft section 8', a section for supporting the bobbin 3 carrying the non-twisted yarn 2 is formed, on which a two-for-one twisting device 21 is provided.

  • Patent number: 5706995
    Abstract: An apparatus for treating a cloth strip comprising a treatment zone with an entrance and exit for the cloth strip. The cloth strip is treated while running along a predetermined spiral path through a treatment zone. A plurality of conveying rollers are provided in the treatment zone. The conveying rollers have portions which are fixed to a rotary shaft and portions which are loosely connected to the rotary shaft such that the loosely connected portion may rotate about the shaft.
