Definitions

  • the invention relates to a device for continuous compression or for determining the mass of a fiber sliver with a pair of rollers that can be pressed against one another, the peripheries of which engage in one another in such a way that a laterally delimited clamping zone is created, and a funnel feeding the fiber sliver.
  • Compression and measuring devices for fiber tapes made of textile fibers following a card or on a draw frame have long been known and in use.
  • the present invention is based on the object of preventing the lateral escape of fibers from the clamping area of the rollers and the resulting jamming of the device and formation of disruptive fiber accumulations.
  • FIGS 1 and 2 are a cross section through Clamping or compression lines or zones 1 of two different configurations of roller pairs 2, 3, and 4, 5 respectively.
  • the roller 3 has a peripheral groove 6, in which a peripheral flange 7 of the roller 2 engages with little play between the side surfaces 7 'of the flange 7 and the side surfaces 6' of the groove 6.
  • FIG. 2 A somewhat different embodiment is shown in FIG. 2.
  • the peripheries of the rollers 4 and 5 are designed in the same way in a step-like manner and, arranged in mirror image, likewise form a compression or clamping line 1 in the center
  • the axes of rotation 8, 9 of the rollers 2, 3, and 4, 5 are pressed against one another in the usual way and their mutual center distance d can be used as the measurement variable.
  • FIG 3 shows the position of the sliver funnel 10 according to the invention in relation to the roller pairs 2, 3.
  • the funnel center axis 11 of the funnel 10 runs essentially at right angles to the connecting plane of the two roller axes 8, 9 through the clamping line 1.
  • the opening 12 of the funnel 10 on the output side extends just so far into the wedge gap 13 in front of the clamping line 1 that a sliver emerging from the opening 12 14 cannot extend beyond the lateral extension a (width of the clamping line 1) up to the clamping line 1.
  • Fig. 4 shows the situation with stair Miger design of the rollers 4,5, where the side surfaces 17, 18 and 19, 20 face each other with little play.
  • the maximum diameter of the opening 12 of the funnel 10 is preferably kept even smaller than the lateral extent a of the clamping line 1, or of the wedge gap 13.
  • the part of the funnel bore 16 running within the overlap zone 15 of the side surfaces 6'7 'or 17, 18 and 19.20 is made cylindrically.
