Problems solved by technology

The teeth of the second comb segment region are configured such that the combing effect is lower than at the end of the first comb segment region arranged opposite the direction of rotation
[0009] Despite these known solutions, during the bonding process, irregular and unsatisfactory results were often observed in previous cards, especially when these cards were operated at high nip rates

Embodiment Construction

[0035] The corresponding parts are in Figures 1 to 7 Indicated with the same reference numerals. Details of the exemplary embodiments taken alone and explained in more detail hereinafter may also form part of the inventive or patentable subject matter.

[0036] figure 1 An exemplary embodiment of a carding machine 1 for carding textile fibers 2 is shown, said figure showing only some components of this carding machine 1 . Therein, the card has a nipper assembly 3 with an upper nipper 4 and a lower nipper 5 for feeding the textile fibers 2 to be carded. The upper nipper 4 and the lower nipper 5 can be opened and closed during the carding cycle (=nipping cycle). exist figure 1 , shows the open state. The nipper assembly also performs a relative movement with respect to the other machine components of the carding machine 1 , in particular with respect to the separating unit 6 comprising stationary traction rollers 7 , 8 , 9 and 10 . The pulling rollers 7 to 10 are arranged...

Abstract

A circular comb (16) fastened to a shaft (14) of a carding machine (1), rotatable about an axis of rotation (13) in a carding direction (26), the card being configured to card textile fibers (2) and having Fixed draw-off rolls (7, 8, 9, 10) for carded textile fibers (11). The circular comb (16) has: a circular comb body unit (17) with an exterior (18); a combing segment (19) with a plurality of combing bars (22) arranged on the exterior (18) of the circular comb body unit (17) , the combing bar is equipped with outwardly protruding combing teeth (23), so that when viewed in said combing direction (26), its front combing teeth sides are each inclined along said combing direction (26); and an alignment section (20) arranged in the exterior (18) of the circular comb body unit (17) and provided with a plurality of outwardly protruding alignment features (25) such that when viewed in said combing direction (26), The front alignment member sides are each inclined opposite to the carding direction (26) and some of them are arranged one behind the other when viewed in the carding direction (26).

Description

[0001] This patent application claims priority from German patent application DE 10 2017 201 678.8, the content of which is hereby incorporated by reference. technical field [0002] The invention relates to a circular comb to be fastened to the shaft of a carding machine, said shaft being rotatable in the carding direction about an axis of rotation, said carding machine being intended for carding textile fibers and having a fixed traction roller. Background technique [0003] Combs, for example for carding machines and configured as circular combs or circular combs, are known from previous public use, wherein carding elements are arranged on a circular comb body in order to engage fiber tufts of textile fibers to be carded. A comb provided with combing elements along at least a part of its circumference is called a circular comb. Its effective combing area can be, for example, 78°, 90°, 111° or 137° of the circumference of the circular comb profile. The carding element ca...
