Definitions

  • the present invention relates to a method and apparatus for producing yarns, particularly from fibers having different properties, in an open-end spinning machine.
  • the invention more particularly relates to the spinning of yarns from fibers which differ with respect to denier, length, type and color, wherein the spinning is performed in open-end spinning machines which include a break-up roller and a spinning turbine arranged coaxially with respect to the break-up roller, and the fiber material used is in the form of processed rovings.
  • the desired mixture of the various fibers was prepared before or during the production of the rovings to be used in the spinning machine.
  • the rovings to be introduced into the spinning machine were thus already composed of the mixture of fibers which the finished yarn was to contain.
  • a roving composed of a given mixture of fibers is guided over a feed roller to the break-up roller of the open-end spinning machine.
  • the roving is then broken up into individual fibers by the break-up roller. Due to centrifugal forceproduced by the roller, and the flow of air, the individual fibers then enter the so-called fiber collecting trough of the spinning turbine. of the open-end spinning machine in a certain mixing ratio. From there the fibers are removed through the center of the spinning turbine as a yarn.
  • a further object of the invention is to increase the degree of control which can be imposed on the resulting product.
  • a more specific object of the present invention is to produce yarns in an open-end spinning machine from fibers having different properties, where the individual types of fibers are supplied in the form of individual, unmixed rovings.
  • the individual rovings each consist of fibers all having a particular individual property, it being of course also possible to have fibers with different properties mixed together.
  • the present invention involves having fibers with respectively different properties present in individual, independent rovings and mixing these independent rovings together only during the introduction into the break-up roller of the open-end spinning machine.
  • the individual rovings composed of fibers with respectively different properties are introduced to the break-up roller of the spinning machine by means of a separate feed roller for each roving.
  • Each of the feed rollers may be operated at a respectively different feed speed so that a certain mixing ratio with respect to the input of the fibers can be realized.
  • the mixing ratio with respect to the individual types of fibers can also be varied or set in a certain way, if all the feed rollers have the same feed speed, by supplying the feed rollers with roving masses of different densities.
  • FIG. 1 is a longitudinal cross-sectional view of an open-end spinning machine according to the invention having two superimposed feed rollers.
  • FIG. 2a is an axial cross-sectional view of an openend spinning machine according to the invention having two feed rollers arranged at the periphery of the break-up roller.
  • FIG. 2b is a cross-sectional view taken along line llb-I Ib of Fibure 2a.
  • FIG. 3 is a longitudinal cross-sectional view of another open-end spinning machine according to the invention having a single feed roller and a triple input of rovings to this feed roller.
  • roller 5 is of standard construction and is mounted and rotated in a known manner. This roller is provided with a series of axially extending, radially spaced fins, as shown, which act to break up the streams of rovings.
  • the rovings l and 3 are broken up into individual fibers and these individual fibers mingle with one another.
  • the mixed individual fibers then reach the so-called fiber collecting trough 7 of a spinning turbine 6 via whose center, or extrusion bore, 8 they are then extruded or expelled as yarn.
  • Turbine 6 is also constructed, mounted and rotated according to principles and procedures which are standard and well-known in the art.
  • the feed rollers 2 and 4 may be superimposed relative to their axes of rotation, as shown in FIG. 1. As shown in FIG. 2, the feed rollers 2 and 4 may just as well be arranged adjacent one another along the periphery of the break-up roller.
  • the principles of the present invention can also be employed by providing a single feed roller 4', as shown in FIG. 3, and by supplying this feed roller with individual streams of rovings 1, 3 and 7, each consisting of respectively different fibers.
  • the devices supplying streams 1, 3 and 7 in the various illustrated embodiments can, in practice, be constituted by any arrangements currently employed in the industry for supplying a stream of rovings of a single material or a mixture of materials.
  • rovings from the several streams will form a suitably homogeneous mixture as they travel along the conical break-up surface of roller 5 and through collecting trough 7.
  • Practical embodiments of the invention can be assembled from known, commercially available spinning turbines, constituting units 5 and 6, feed rollers, constituting units 2, 4 and 4', and devices capable of supplying streams of rovings 1, 3 and 7.
  • the following speed conditions may, for instance, occur at feed rollers 2 and 4:
  • Feed roller 2 feeds a stream of roving l weighing 2 glm at a speed of 0.5 m/min.
  • Feed roller 4 feeds a stream of rovings 3 weighing 2.4
  • apparatus for spinning yarn formed of a blend of different types of fibers the fiber types differing from one another with respect to at least one property
  • the apparatus including an open-end spinning machine composed of a rotating break-up roller and a spinning turbine rotating coaxially with the roller, and at least one feed roller rotatively mounted for delivering a stream of rovings of such fibers to the break-up roller, the improvement comprising means supplying each different type of fiber separately to said at least one feed roller; whereby the different types of fibers become mixed together only subsequent to being supplied to said at least one feed roller.
