Definitions

  • the invention relates to a spinning machine drafting system Bottom rollers and with top rollers as well as with bottom straps and with ankle strap.
  • the present invention goes from a pneumatic fuse compaction unit, at which the fiber structure by sucking on along the Fiber row extending hole row summarized laterally through which air is sucked in by means of suction.
  • This Row of holes can be in a drafting roller, both in a lower roller as well as in an upper roller or in a the straps leading the fiber structure may be arranged.
  • the invention is described below using a device, in which the row of holes in a top roller assigned Strappy is arranged.
  • the compression function of the drafting system is said to be to be dispensed with. This cannot be seen simply by Turn off the suction of the match compression unit, because doing so will guide the fibers in the by then the area under the perforated area that acts as a compression field Strappy no longer exists. Also a replacement of the fuse compaction unit is not by a simple roller expedient because there is no guidance of the in the last stretch Fibers are present and thereby the quality of the produced Fadens would be affected. The invention was therefore asked the task to provide a simple solution for this.
  • Changing the positions is particularly easy of the drafting rollers when the bearings of the bottom rollers or the brackets of the top rollers are identical, so that it is easily moved to other positions and can be used. At least one is also advantageous approximately the same diameter of the lower rollers of the drafting system, because this means that their peripheral surfaces also in other positions are at least approximately the same height and the in generally flat fiber tread at least approximately flat remains.
  • the drafting device 1 has in its Arrangement for compaction spinning four usually corrugated Bottom rollers 2, 3, 4 and 5 made of steel.
  • the bottom roller 3, which is often "corded” i.e. is cross corrugated, by wrapped around a lower strap 11, which before the following A pair of rollers also around a turning rail, not shown here is led.
  • the output lower roller 5 is usually in the punch 6, the other lower rollers, however, are in sledges 7, 8 and 9 stored in the punch in the direction of Are adjustable.
  • the bearings of the lower rollers 2, 3, 4 and 5 are identical, so that each lower roller in each of the carriages 7, 8 or 9 or in the bearing in the punch 6 can be inserted.
  • the lower rollers 2, 3, 4 and 5 also have at least approximately the same diameter on, so that when the lower rollers are moved, the plane of warpage of the drafting system 1 at least approximately upright is obtained.
  • the bottom rollers 2 and 4 are normal top rollers 10 with elastic Assigned reference.
  • Upper roller 10 is wrapped by an upper strap 12, the from a common strappy cage, not shown here is guided with a deflection rail.
  • An upper roller 13 is assigned to the output lower roller 5, which is also wrapped by an upper strap 14.
  • This top strap 14 has a row of holes 15 which are in the center is arranged around its circumference.
  • a chamber 16 is also provided, which against the the fiber sliver 17 facing strand of the top strap open or provided with a perforation and via a pipeline 18 connected to a suction source, not shown here is.
  • the top roller 13, the top strap 14 and the chamber 16 form a compression unit 19th
  • the top rollers 10 and 13 are usually called Rolling twins executed and by means of links 20 in one common support and load arm 21 supported.
  • the roller holder 22 of these links 20 are identical, so that the upper rollers 10, 13 easily in a different position can be inserted into one of the roller holders.
  • a roving guide 23 is arranged upstream of the drafting unit 1 and one Thread guide 24 and a ring / traveler / spindle unit, not shown Subordinate common construction.
  • the roving 25 fed between the successive Roller pairs, i.e. the input roller pair 2/10, the top apron roller pair 3-11 / 10-12 and the delivery roller pair 4/10 continuously refined and as fiber fuse 17 in its final fineness to that from the lower roller 5 and the compression unit 19 existing compression and Delivered pair of output rollers. This warp is in the warp 17 run in width.
  • the fiber sliver 17 is summarized and compacted and narrow and without protruding fibers as thread 26 via the thread guide 24 to the ring / traveler / spindle unit delivered.
  • the invention provides that after removing the compression unit 19 and its associated Bottom roller 5 the remaining stretching rollers each a position in the direction of the sliver 17 run be moved on. So it becomes the lower roller 4 in the previously taken up by the lower roller 5 bearing in the Punch 6, the lower roller 3 in the bearing of the carriage 9 and the lower roller 2 in the bearing of the carriage 8th offset, the carriage 7 remains free. Where appropriate the distances of the carriages 8 and 9 to the fixed position to adapt the new output lower roller 4 in the punch 6.
  • the upper rollers 10 are correspondingly in the roller holder 22 to move the corresponding handlebar 20. From Fig.
