Problems solved by technology

[0008] The method described above has the disadvantage that the strip is fed directly to the combing head by the card or the downstream drafting device while it is temporarily stored in the can
The belts placed side by side result in a material accumulation in addition to material voids, so that the clamping in the nippers of the combing machine is not optimal and thus an excessively high proportion of combed noil due to the separated long fibers

Embodiment Construction

[0065] exist figure 1 shows how the winder 1 is used, for example, in the textile industry in combing shop preparation. A plurality of fiber strips 3 , which may be made of natural or man-made fibers, are conveyed through the cans of the winder 1 and compared in a drafting device (not shown) and optionally in a table calender. The fiber strip 3 is conveyed further via the feed zone 2 to a plurality of pressure rollers 4a-4c, which guide the fiber strip 3 into the draw-in zone between the two winding rollers 5a, 5b and the winding sleeve 6 . A precompressor 8 is arranged in or on the feed area 2, which precompressor adjusts the fiber belt 3.

[0066] As an alternative to the embodiment with two winding rollers 5 a , 5 b , winding machines are known in which laps are formed inside or via a belt with winding rollers inside a surrounding belt.

[0067] An example of an embodiment of a cotton reel 10 according to the invention is symbolically at figure 2 shown in . Cotton win...

Abstract

The invention relates to a lap machine for producing a lap web from at least two slivers (3), comprising a drive apparatus (21) by way of which the lap is conveyed through at least one precompressor (8), wherein the precompressor (8) doubles the individual slivers (3) to form a lap web. The invention is characterized in that the slivers (3) are deflected and / or compacted or doubled within the precompressor (8), wherein the deflection and / or compaction or doubling is settable. The invention furthermore relates to a method for producing a lap from slivers.

Description

technical field [0001] The present invention relates to a coiler and a method for producing laps from fiber strips. Background technique [0002] The currently customary yarn feeding of flat combs takes place via laps, which were previously produced from the individual belts in the winder. For this purpose, the winder receives the sample in strip form from at least one path, wherein the sample is temporarily stored in circular or rectangular cans. The winder generally comprises a winding unit with at least two winding rollers, on which the lap is formed by means of a sleeve. Upstream of the take-up unit is usually at least one pair of press rollers which join 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. [0003] The quality of the laps produced is decisive for the productivity of the downstream combing machine. Based on lap dimensions defined with a weight of ...
