Embodiment Construction

[0032] figure 1 A section for drafting (homogenizing) the tow-shaped fiber bundle 2 is shown schematically in side view and as an example of a textile machine 11 according to the invention. During the operation of the section, fiber bundles 2 (for example in the form of fiber sliver) are taken out of one or more so-called spinning pots 16 by means of a withdrawal device, and are fed to the section by means of corresponding diverting devices 18. The respective drafting device 1 (or, in the case of a multi-head segment, several drafting devices 1 delivered to a segment).

[0033] The drafting device 1 generally consists of three or more roller pairs, which may each comprise at least one lower roller and an upper roller. The desired pulling of the fiber bundle 2 is ultimately produced by the fact that the respective cylindrical lower roller and thus the respective upper roller in contact with it has an increasingly higher circumferential speed. Although other solutions are als...

Abstract

The invention relates to a textile machine, in particular a pre-spinning spinning machine, comprising: a drafting device (1) for drafting a fiber bundle (2) fed to the textile machine (11); A compactor (4) for compacting the fiber bundle (2), said compactor (4) being arranged downstream of the drafting device (1) in the transport direction (T) of the fiber bundle (2); and for withdrawing A withdrawal device ( 5 ) for the drawn-off fiber bundle ( 2 ), which is arranged downstream of the compactor ( 4 ) in the conveying direction ( T ), wherein the drafting device ( 1 ) comprises at least one input cylinder (7) drivable by means of a drive (6) and an output cylinder (8) drivable by means of a drive (6), and wherein the extraction device (5) comprises at least one The extraction disc (9) is driven by the driving device (6). According to the invention it is provided that the textile machine (11) comprises means by means of which it is possible during operation of the drafting device (1), at least in the initial phase (I) and / or Or change the ratio of the peripheral speeds of the output cylinder (8) and the withdrawal disc (9) during a part of the stop phase (III) (= tensioning pull (A)).

Description

technical field [0001] The invention relates to a textile machine, in particular a pre-spinning spinning machine, with a drafting device for drafting the fiber bundles fed to the textile machine; a compactor for compacting the fiber bundles, It is arranged after the drafting device in the conveying direction of the fiber bundle; and a withdrawal device for withdrawing the drawn fiber bundle is arranged after the compactor in the conveying direction, wherein the drafting device comprises at least one An input cylinder drivable by means of a drive and an output cylinder drivable by means of a drive, and wherein the extraction device comprises at least one extraction disc drivable by means of a drive. In addition, a method for operating a corresponding textile machine is proposed. Background technique [0002] It is known from the prior art, especially in the case of drafting, to guide the fiber material drawn by the drafting device, which is mostly present as fiber webs (Fase...
