Definitions

  • the invention relates to a spinning machine with a drafting system, that delivers at least one fiber sliver to a pair of output rollers and which has a rotating suction roller at its exit, which the at least one fiber sliver by suction on a perforation track under suction is compressed, the Suction area by means of a arranged inside the suction roller Coverage is limited to a compression zone.
  • the suction roll has a larger diameter than the usual Straightening rollers, since it is hollow and not one inside co-rotating, the perforation track on part of the circumference the screen covering the suction roll must contain the suction limited to the area in which the fiber sliver passes over the suction roll is led.
  • the invention therefore proposes to do without this strappy and thereby the Suction roller driving lower roller and the output lower roller of the drafting system independently to make each other drivable.
  • the suction roll be the input of the Assign the organ that defines the compression zone.
  • This organ can act as another bottom roller of the suction roll or as a loop wrapping around the exit lower roll of the exit roll pair, straps extending to the circumference of the suction roll may be formed.
  • one of the two rollers preferably the suction roller, with an elastic Topping.
  • the perforation can usually be introduced at the same time their holes through the elastic covering and made mostly of metal jacket of the suction roll through become.
  • both in the coat and in elastic covering a groove may be provided. This measure has the further advantage that the pitches and the diameter of the suction openings of the perforations in the jacket and in the elastic The covering of the suction roller does not have to match.
  • Suction roller to assign a further lower roller by a Conveyor strap is wrapped, which is known by means of Guide means such as a deflection rail close to the Clamping line of the pair of output rollers of the drafting system extends.
  • Guide means such as a deflection rail close to the Clamping line of the pair of output rollers of the drafting system extends.
  • the fiber bandage is carried by the strap supported and prevented from tearing off.
  • the compression of a fiber sliver delivered by a drafting system offers the advantage that the fiber sliver is summarized closely can be fed to the twist zone in which it becomes a yarn is solidified. Jumps into this tightly summarized fiber sliver the rotation given to it by the rotation device to close to the clamping line, i.e. the spinning triangle is very small. This has the consequence that the loss of splitting edge fibers is minimal and that the yarn produced has little protruding fibers has, i.e. has low hairiness. It has shown, that this beneficial effect of compression spinning through thread balloonless or thread balloon reduced spinning even further can be increased. Thread balloonless or thread balloon reduced Spinning reduces the thread tension in the thread piece between the pair of output rollers of the drafting system and the spindle tip and increases the twist density in this thread piece. Apparently support these effects by compressing the fiber sliver effect.
  • a possibility for thread balloonless or reduced thread balloon Spinning exists when using ring spinning devices for turning and winding the fiber sliver using Spindle attachments such as spinning fingers or spinning crowns.
  • Pot spiders also reduce thread tension in the piece of thread between the placement point of the yarn in the spinning pot and the output roller pair of the drafting system in comparison with a ring spinning device.
  • the arrangement can be such that the individual Workplaces compacted fiber slivers each one Rotation-imparting organ fed like a ring spinning spindle - single yarns are produced here.
  • the arrangement can but also be such that there are always two condensed fibers and run together to an organ that gives the rotation - so-called false twine is created.
