Problems solved by technology

It has proved impossible to achieve the parallelism of the individual fibers in the fiber fleece required for high-quality yarn requirements, especially when combers are operated at high operating speeds and using such top combs, while at the same time it is possible to observe the heavy contamination, which necessitates frequent cleaning

Embodiment Construction

[0020] The drawing schematically shows a method according to the invention for producing a comb element according to the invention.

[0021] In the following, the invention is explained with reference to the accompanying drawings, which explicitly refer to all the details that are important to the invention and that are not specified in the details of the description. The single figure shows schematically a method according to the invention for producing a comb element according to the invention which is suitable for producing a top comb according to the invention. According to the figures, raw material blocks, such as blocks made of high-alloy stainless steel, such as chrome-nickel steel, are used as basic raw material for the manufacturing process. The width b of the block of raw material may be up to 300 mm, while the height h of the raw material may be 5 to 15 cm, in particular 10 cm. The depth t of the block of raw material may be 1 to 10 mm, specifically 3 to 5 mm. In ...

Abstract

Teeth for fitting to the top comb or the combing cylinder are grouped as part of a solid block placed transversely to the combing direction. The teeth are in one piece with a solid back, which is shaped to form the attachment device. Preferably more than three teeth groups are placed in line in the combing direction. An independent claim is included for the method of producing the teeth by spark erosion from a solid block (10). Initially slots (12) are machined by a multiple erosion head (20). The tooth shape (52) and attachment zone (54) are then produced by profiling heads (30, 40) working simultaneously from both ends.

Description

technical field [0001] The invention relates to a combing unit for a combing machine having at least one circular comb and at least one top comb and a plurality of combs for engaging fiber fleeces arranged side by side in a direction approximately perpendicular to the combing direction. comb teeth. Background technique [0002] Combing machines are used to refine the yarns made from textile fibers. In the manufacture of yarn, combers are usually arranged between the carding station and the drawing station. The main tasks of the comber include the removal of short fibers from the carded sliver produced by the carding station, i.e. improving the stacking of the virgin fiber material and improving the parallelism of the individual fibers in the fiber fleece supplied by the carding station in the form of a carded sliver . As a side effect, further cleaning of the fiber fleece is achieved in the comber by removing neps and seed particles. In order to achieve the above-mention...
