Definitions

  • the invention relates to a weft store for a loom, with a winding body having radially adjustable peripheral elements, which is arranged eccentrically to a fixed axis of the weft store, and a balloon breaker for the weft to be removed from the winding body and to be inserted into the loom of the loom.
  • the object of the invention is to create a weft thread store which is particularly improved in this regard.
  • the invention resides in a circular thread guide element arranged on the thread take-off end face of the winding body, concentrically arranged relative to the balloon breaker and to the fixed axis of the weft thread store, for generating constant circumferential distance between the winding body and the balloon breaker.
  • the centrifugal force arising in the weft thread drawn off and coming into the loom, as the tests have shown, can be kept essentially constant.
  • the weft thread then no longer strikes the balloon crusher but instead runs tangentially along the inner circumference of the balloon crusher with the constant centrifugal force.
  • Even sensitive weft yarns, such as B. glass fiber materials can then be entered into the loom of the loom without damage.
  • the resulting tissue contains no tissue defects, e.g. B. more visible, discontinuous places that would be due to fibril breaks in the weft.
  • an intermediate disk 18 is fastened and, by means of a screw 19 arranged eccentrically to axis 3 and a cover 20, a thread guide disk 21 shown broken off towards the center in FIG. Its rear part 22 is extended around the carrier disk 18.
  • the winding body 25 is enclosed by a balloon breaker 26 arranged concentrically to the axis 3, by means of which the balloon 27 of the weft thread 16 drawn off is delimited.
  • the weft thread passes through an eyelet 52 of the schematically indicated weaving machine 53 into the shed 55 formed by the warp threads 54.
  • the thread guide disk 21 ensures that the distance D between the disk 21 and the balloon breaker 26 - as is particularly evident Fig. 2 shows - is essentially the same size over the entire circumference.
  • the thread balloon 27 therefore slides at 34 on the guide disk 21 and at 35 on the inner circumference 37 of the balloon breaker 26.
  • the centrifugal force that occurs in the balloon 27 changes at most only slightly during thread withdrawal. This means that even sensitive yarns can be processed, e.g. glass fiber material.
  • the constant centrifugal force in the thread balloon 27 prevents the drawn weft thread in the region of the balloon 27 from striking the inner circumference 37 of the balloon breaker 26 with uneven strength, as a result of which breaks in the individual fibrils of the weft thread 16 and thus tissue defects can be prevented.
  • the winding body 25 consisting of the parts 2, 5 can stand still and the weft thread 16 is fed through a tubular winder (flyer) 39, indicated in dashed lines in FIG. 2 and rotating according to arrow 38.
  • a ring can also be used as the thread guide member on the take-off side 17 of the winding body 25, the shape of which can approximately correspond to the part of the disk 21 shown in FIG. 2.
