Definitions

  • the invention relates to a method and an apparatus for producing a yarn or the like. according to the preamble of claim 1 or claim 8.
  • Another disadvantage of this device is the need for both friction spinning drums to be perforated and to be under negative pressure in order to guide the fibers released onto the drum into the corresponding gusset gap at the yarn formation point.
  • the device is very complex and bulky due to the double-sided feeding of the fibers.
  • an open-end friction spinning device is known from DE-OS 3 242 801, which comprises two friction spinning drums running parallel to one another, at least one of which is perforated.
  • a suction channel is connected to this, which generates an air flow in order to hold staple fibers supplied to the friction spinning drum on the surface of the friction spinning drum so that they can be fed to a yarn formation point.
  • the staple fibers are released from their fiber structure by a first and a second known dissolving device and fed to the friction spinning drum at two fiber transfer points arranged next to one another in the yarn take-off direction.
  • yarns can now be produced from one or two different staple fiber components; however, the distribution of the staple fibers over the yarn cross section cannot be influenced. Rather, there is always a uniform mixing of the staple fibers in the finished yarn.
  • a friction spinning process is known from AT-PS 373 634, in which a stretched fiber sliver is wound with staple fibers.
  • a friction spinning device which has two perforated spinning drums which are arranged parallel to one another in their direction of rotation and through which an air stream is sucked off in each case.
  • the fiber sliver is fed to a gusset area serving as a yarn formation point between the spinning drums in the yarn take-off direction.
  • the parallelized staple fibers triggered by a drafting system from a fiber structure are fed directly to the gusset area between the spinning drums in order to be spun around the fiber sliver as sheath fibers.
  • a major disadvantage of this known device is that both spinning drums must be perforated and must be under negative pressure, since this is the only way to ensure that the staple fibers are properly fed.
  • two fundamentally different devices are required to feed the different fiber materials to be spun, which devices must also be spatially separated from one another, which leads to a complex and undesirably voluminous friction spinning device.
  • a friction spinning device in which staple fibers are transferred from a converging fiber feed device to a perforated drum.
  • a pressure roller is provided just above the fiber transfer point, which forms a nip point with the perforated drum.
  • a further fiber feed device is arranged behind the clamping point in the yarn take-off direction, with which further staple fibers are transferred to the perforated drum.
  • the fiber sliver formed on the drum 22 is guided over a rotating friction disk, so that the sliver is spun into the yarn.
  • the staple fibers are thus transferred purely pneumatically at the two transfer points, with the staple fibers being swirled pneumatically at the first fiber transfer point.
  • the invention is based on the object of creating a method and a device of the type mentioned at the outset, by means of which more than one fiber feed per yarn formation can be realized in the simplest possible way, in order thereby to effect a specific distribution of the fibers in the finished yarn, at the same time, the best possible parallelism of the staple fibers of a component is provided with one another.
  • the transfer of mechanically guided staple fibers according to the invention to a friction spinning means at two fiber delivery points arranged one after the other in the yarn take-off direction means that the staple fibers transferred from the first fiber delivery point and the staple fibers transferred from the second fiber delivery point can be located on the periphery of the finished yarn.
  • the individual transfer parameters, such as transfer speed and transfer angle at the individual fiber delivery points, can not only be set independently of one another, but can also be easily maintained for the individual staple fibers of the two fiber components.
  • the increase in the staple fibers of the two fiber components in the finished yarn can be chosen differently without causing an undesirable mixing of the two fiber components, the staple fibers of one component being aligned with one another in accordance with the set pitch, since the fibers do not fly freely during the process .
  • Yarns can thus be produced in which either long or short staple fibers, natural fibers or synthetic fibers can be provided on the inside or outside.
  • the production of coarse yarns for example smaller than Ne 16 can be carried out by dissolving the sliver fed to the pulping unit, which allows the fibers to be separated before they are released onto the friction spinning agent, which is advantageous for the spinning process.
  • the method according to the invention can be used in a particularly advantageous manner for the production of fantasy yarns.
  • Fig. 1 shows schematically one known from the rotor-open-end spinning unit 1 or 2, which is fed with a sliver 3 or 4.
  • the dissolving units 1 and 2 each contain an opening roller (not shown) provided with needles or teeth, which releases fibers from the sliver 3 or 4 and transfers them to a fiber conveying channel 9 or 10 connected to the opening unit 1 or 2, respectively.
  • the fibers 13 are delivered in a position identified by 13.1 to the surface of a first friction spinning drum 14 known per se, which is moved in the direction of arrow U.
  • This first friction spinning drum 14 is perforated (not shown) and provided on the inside with a suction channel 15 (FIG. 2) which is known per se and which is connected by means of a connection 16 to a vacuum source (not shown).
  • a suction duct 15 By means of this suction duct 15, air is sucked into an area S delimited by the duct walls 15a and 15b through the perforated first spinning drum, so that on the one hand air for pneumatic fiber transport is sucked through the fiber conveying ducts 9 and 10 and on the other hand the fibers 13 in position 13.1 this sucked-in air is held on the spinning drum surface and transported to the yarn end 17 located in the yarn formation point 18 so that these fibers can be taken up by the yarn end 17 and rotated to this yarn end.
  • the finished yarn 19 is drawn off in the pull-off direction G by take-off rollers 20.
