Definitions

  • the invention relates to an opening roller for open-end spinning machines according to the preamble of claim 1 and claim 4.
  • needles or needle strips or sawtooth wires are known as a clothing for such rollers.
  • the latter can be produced and wound up inexpensively, but they do not guarantee optimal combing quality.
  • needle sets are very advantageous, but usually require more effort for the initial set or for the renewal that becomes necessary at regular intervals.
  • a generic needle roller which has undercuts running parallel to its longitudinal axis, into which the base made of metal can be inserted by needle strips for fixing.
  • the foot of the needle bars has a longitudinal recess on its underside, so that two legs which are elastically deformable inward are formed.
  • a profile formed in this way has great torsional rigidity.
  • the tips of the needles of a roller garnished in this way necessarily lie on lines parallel to the longitudinal axis of the roller, so that the tip distribution is not optimal.
  • the object of the invention is to create an opening roller which, with continuous, even engagement in the fiber sliver, enables the use of light and thus unbalance-insensitive roller bodies, with additional re-operations during operation. of the user can be done quickly and easily.
  • pinstripes with a certain inherent elasticity of the foot, the pinstripes being held parallel to the longitudinal axis of the groove without additional fixing means, and in the radial direction a corresponding projection on the foot corresponding to the undercut the pinstripe can provide support.
  • These pinstripes can thus be used without having to carry out heating for loosening glue or solder connections, which can lead to the rollers treated in this way having to be re-balanced, which requires a corresponding technical outlay.
  • roller bodies with a helical circumferential groove which according to the invention runs at an acute angle to the longitudinal axis of the base body, can be produced inexpensively and with the required precision from light aluminum parts by using a spiral milling device.
  • an optimal needle distribution over the guide width is achieved by the arrangement of the pinstripes according to the invention.
  • Claim 2 specifies a particularly advantageous dimensioning for the angle between the grooves and the longitudinal axis.
  • the design of the undercut as a dovetail profile, provided in accordance with claim 3, enables a particularly reliable fit of the pinstripes.
  • Claim 4 specifies a ratio for the dimensioning of the groove pitch and the longitudinal axis of the cylinder, by means of which a further, very favorable needle distribution is achieved.
  • An opening roller according to the invention comprises a base body 1. Grooves 2 running parallel to one another are introduced into this base body 1 by means of a spiral milling device. In cross section (see FIG. 2), these grooves 2 have a dovetail profile. They run helically relative to the cylindrical base body 1.
  • Each individual groove 2 has an inclination a between 5 ° and 30 ° in the projection relative to the longitudinal axis 3 of the base body 1.
  • a slope of a 13 ° was chosen.
  • the slope a is based on the length 1 of the base body or the width d of the grooves 2 so chosen that in a direction parallel to the longitudinal axis 3 the center 4 of the end of a groove 2 on an end face 5 of the base body 1 is at the same height as the center 6 of an adjacent groove 2 on the other end 7 of the base body 1.
  • the garnishing is illustrated by means of a pinstrip 8, for example using a groove.
  • a pinstripe consists of a plurality of needles arranged in a row, which are connected to one another by a foot 9 which is injection molded from plastic.
  • a plastic is selected which on the one hand has a dimensionally stable, hard-wearing surface and on the other hand has such inherent elasticity that it can easily follow its helical course when inserted into a groove 2.
  • 10 washers can be applied to the hub lugs to fix the pinstripes.
