CZ283255B6 - Comb for textile combing machines - Google Patents

Abstract

In a clothing for textile combing machines, such as combing machines for wool, cotton or similar synthetic or natural fibres, comprising saw-toothed stamped parts with at least two rows of teeth extending transversely relative to the combing direction, in order to achieve a tip offset at a low outlay in terms of production, along with simple clothing, the planes of respective teeth (5) succeeding one another within a stamped part (1) are arranged offset relative to one another. <IMAGE>

Description

Technical field

The invention further relates to a combing comb for textile wool and cotton combing machines comprising a plurality of juxtaped needles or sawtooth-shaped studs with tips, the tips of the needles or studs projecting freely downwards.

BACKGROUND OF THE INVENTION

The comb comb of the type described is known from DE-A-3 722 481. Comb combs are used in combing machines for combing wool or man-made fibers and combing cotton. The combing comb must in this case carry out the cleaning of portions of the fibers which cannot be retained by the circular comb arranged upstream of the comb comb, considered in terms of the burr removal direction. As a result, the comb combs are regularly clogged and dirt from wool or cotton, which consists of plant parts or substances, is deposited therein. The short fibers or impurities deposit in the gaps between the flat needles distributed in the combing direction.

It is an object of the present invention to further improve the comb comb of the above type so that it is cheap to manufacture, the comb comb is easy to assemble, and combing efficiency is improved.

SUMMARY OF THE INVENTION

This object is achieved by a combing comb for textile wool and cotton textile combing machines comprising a plurality of juxtaposed needles or serrated sawtooth-like shapes, wherein the tips of the needles or moldings protrude freely downwardly according to the invention freely protruding parts curved sickle-shaped.

It has been found that densification occurs within this curvature, which causes particularly high-quality combing. The radius of curvature is preferably between 8 and 35 mm, the curvature extending over an angle of from 18 ° to 100 °.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a partial perspective view of a comb comb according to the invention with curved needle tips; FIG. 2 is a side elevational view of the comb comb of FIG. 1; and FIG. Fig. 1.

DETAILED DESCRIPTION OF THE INVENTION

1 to 3 shows the comb comb according to the invention. The comb comb 10 consists of a rigid support 11 arranged on the respective textile machine and a cover sheet 12, with a plurality of needles 13 arranged between the support 11 and the cover sheet 12. The tips 14 of the needles 13 protrude freely beyond the lower edges 15, 16 of the support 11. In the region of these free protrusions, as shown in particular in FIG.

Is 8 to 35 mm, with the center M, the curvature being in the range of an angle of magnitude of 18 ° to 100 °.

Claims (3)
