Definitions

  • the invention relates to a device for increasing the adhesive length according to the preamble of main claim 1.
  • the sliver represents an intermediate product in the spinning process, which is formed for the first time after the card. It is used for submission or further processing on the subsequent spinning machines.
  • DE-OS 33 19 514 shows a pair of toothed rollers for transporting a sliver.
  • the tooth height is relatively large, which means that the sliver can dodge.
  • the invention has for its object to provide a device for increasing the adhesive length of fiber tapes, the increased adhesive length is maintained at the next processing stage and the action taken on the fiber tape does not have a disadvantageous effect on subsequent processing machines and does not lead to damage to the fibers.
  • a depression of 0.5 mm has proven to be advantageous. Sufficient crimping of the fibers is thereby achieved without having an adverse effect on the parallel alignment of the fibers. Further advantages are described and shown in more detail with reference to the following exemplary embodiment.
  • the sliver 1 is fed to a compressor hopper 3 via a conveyor belt 2.
  • the sliver 1 emerging from the compressor hopper 3 passes between the calender rolls 4 and 5 and is then deposited into a can 7 via a rotating funnel wheel 6.
  • the calendar rollers 4, 5 are each provided with lateral guide flanges 8, 9 which project beyond the rollers in diameter and carry out a lateral guidance of the sliver 1 clamped between the calendar rollers 4 and 5.
  • the roller 5 is pivotally mounted about the axis 10.
  • This pivoting movement is pivoted in by an adjustable stop 12 which is fastened to the pivoting tube 13 of the roller 5.
  • an adjustable stop 12 which is fastened to the pivoting tube 13 of the roller 5.
  • a hand lever 15 is fastened to the swivel tube 13 to swivel the roller 5 away, for example when threading in a new sliver 1.
  • the calender rolls 4 and 5 are provided with tooth-like elevations 16 on their outer circumference. These elevations 16 are of identical design in the case of both rollers 4, 5, so that they can mesh with one another like with spur gear teeth.
  • the stop 12 is set so that the distance a ( Figure 3) is always greater than zero. This is to avoid damage or wear to the rollers 4, 5.
  • the elevations 16 on the tip circle diameter D1 and root circle diameter D2 are rounded off with the radii R1 and R2.
  • the flank 17 of the elevation 16 runs relatively flat, the angle being greater than 45 degrees. This results in a particularly gentle treatment of the sliver and prevents damage to the individual fibers during the pressing process.
  • the guide flange 9 has been omitted in the illustration according to FIG. 3 for reasons of clarity.
  • the calender roll 4 is fixedly mounted on the machine frame 14 and is driven by a drive, not shown in detail.
  • the calender roll 5 is freely rotatably mounted in the swivel tube 13.
  • the roller 5 is also set in rotation by the driven roller 4 by friction. The operation of this facility is as follows:
  • the sliver 1 or the fibers are slightly crimped and changed from an exactly parallel alignment to a wavy alignment.
  • This device is particularly suitable following a combing process, the strip having very short adhesive lengths after combing out, soldering and stretching.
  • This increase in the length of the adhesive substantially reduces the risk of a belt break in subsequent processing machines and, under certain circumstances, enables a belt to be transported over a longer feed distance or to be fed directly to the subsequent processing machine without intermediate storage in a can.
