Embodiment Construction
[0020] The sliver guide 1 shown in FIGS. 1 to 5 serves to feed one or two fiber slivers, rovings or card slivers 2 , 3 and 4 to a drafting unit 5 . The drafting mechanism 5 consists of a plurality of roller pairs, of which only two roller pairs 6, 7 and 8, 9 are shown in FIG. 1 .
[0021] There are driven bottom rollers 6 and 8 on which each presses a top roller 7 and 9 . In the case of a drafting unit 5 for a ring spinning machine, the bottom rollers 6 , 8 are designed as grooved rollers which run along the machine longitudinal direction. The slivers 2 , 3 , 4 are transported along the fiber transport direction A to the drafting unit 5 and drawn to their desired fineness. It can be provided, in a manner not shown, that a compression device is then arranged on the drafting mechanism 5 after an output drafting roller pair, in which the sliver 2, 3, 4 is compressed and squeezed in the compression zone. pressure. The drawn strands are then fed to a common twisting unit.
