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.
- a compression device of this type has become known from BE-A 5091 63, in which the outlet opening of a funnel opens into the interior of the groove of a grooved roller.
- this measure also does not prevent the fibers from becoming jammed between the rotating end faces of the groove and the counter roller penetrating into the groove.
- the counter roller penetrating the groove conveys such edge fibers of the fiber sliver into the gap mentioned, since the fibers emerge from the funnel in a space that is not closed on all sides and thus try to escape laterally.
- 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.
- the fiber outlet opening of the funnel lies within the area of the wedge gap, which is limited by the overlap zone of the side surfaces of the rollers.
- rollers 1 and 2 each show a cross section through the 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, also form a compression or clamping line 1 in the center.
- the side surfaces 17 and 18 of the roller 4 lie with little play to the side surfaces 19 and 20 of the roller 5
- 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 a 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 center axis 11 of the funnel 10 runs essentially at right angles to the connecting plane of the two roller axes 8, through the clamping line 1.
- the opening 12 on the outlet side of the funnel 10 extends just so far into the wedge gap 13 in front of the clamping line 1 that a sliver 14 emerging from the opening 12 cannot extend beyond the lateral extension a (width of the clamping line 1) up to the clamping line 1.
- the lateral limitation for the sliver 14 is ensured by this arrangement within the overlap zone 15 of the side surfaces 6 'of the groove 6 and the side surfaces 7' of the flange and jamming of individual fibers from the bandage of the sliver 14 is excluded.
- 4 shows the situation in the case of a stepped configuration of the rollers 4, 5, where the side surfaces 17, 18 and 19, 20 lie opposite one another 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.
