Embodiment Construction

[0052] exist figure 1 A winder 1 is shown in , as it is used, for example, in combing preparations in the textile industry. A plurality of fiber strips 3 , which may be made of natural or synthetic fibers, are fed through the cans of the winder 1 and compared in a drafting device not shown. The fiber strip 3 is guided through the feed area 2 to a plurality of pressing rollers 4a-4c, which guide the fiber strip 3 between the two winding rollers 5a, 5b and the winding sleeve 6 for producing the lap. in the pull-in area between them. A precompressor 8 , which contrast-adjusts the fiber strip 3 , is arranged in or on the feed region 2 . The winding pressure can be produced by two laterally arranged cylinders, not shown, which draw or press the winding sleeve 6 onto the winding rollers 5a, 5b.

[0053] In addition to the embodiment with two winding rollers 5 a , 5 b , winders are known in which the lap is formed inside a revolving belt or via a belt with winding rollers. Howeve...

Abstract

The invention concerns a precompressor (8) for smoothing and / or compacting a carded sliver in a winding machine, the carded sliver (3) being deflected and / or compacted inside the precompressor (8). The invention is characterized in that the deflection and / or compaction is / are adjustable. The invention further concerns a method of operating a winding machine (5a, 6, 5b).

Description

technical field [0001] The invention relates to a precompressor for flattening or compacting a fiber web in a winder, a winder and a method for operating the winder. Background technique [0002] The feeding of conventional flat combs takes place via laps, which were previously produced from the individual strips in a winder. For this purpose, the winder takes the sample in the form of at least one length of strip, wherein the sample is temporarily stored in a circular or rectangular container. The winder generally comprises a winding unit with at least two winding rollers, on or in which the lap is formed. There is usually at least one pair of press rollers upstream of the winding unit, which combine and / or stretch the belt. An infeed area is arranged upstream of the press rollers in such a way that a further compression unit or a leveler can be arranged. The compression unit usually comprises two or three webs arranged in parallel and at the same height, which adjust th...
