Problems solved by technology

For example, this is carried out by a large number of screwing operations of the clamping plates and the fastening strips and / or by axial pushing in the direction of the central longitudinal axis of the basic body, thus resulting in a long set-up time of the comber and thus a long downtime

Embodiment Construction

[0047] figure 1 The illustrated circular comb 1 has a hollow cylindrical base body 2 with a central longitudinal axis 3 , outer sides 4 and two end faces 5 (only one of the two end faces is visible). The base body 2 rests on a drive shaft 6 which is likewise designed as a hollow cylinder. The base body 2 can also be driven directly, that is to say without an additional drive shaft 6 . For this purpose, the base body 2 can be designed both as a hollow shaft and as a solid shaft.

[0048] A total of nine positioners 9 are arranged on the base body 2 in the circumferential direction 7 , each fastened by means of a fastening device 8 . The positioner 9 defines the combing area of ​​the circular comb with its axial extension / distribution parallel to the central longitudinal axis 3 .

[0049] Each fixing device 8 comprises a profile 10 and a leaf spring 11 , by means of which each positioner 9 is fastened to the base body 2 in a non-positive manner. For unlocking the non-positiv...

Abstract

A circular comb for a combing machine for combing textile fibres, comprising a basic body (2) with a centre longitudinal axis (3), a circumferential surface (4) and two end surfaces (5), a plurality of bar tacks (9; 32; 32a; 42) which are arranged on the circumferential surface (4) of the basic body (2) and fix a combing region of the circular comb, a plurality of fastening devices (8; 38) which are attached to the basic body (2) for the non-positive connection of in each case one of the bar tacks (9; 32; 32a; 42) to the basic body (2), and unlocking units for releasing the non-positive connections, wherein each unlocking unit has an unlocking device (13; 48) and an unlocking means (12) for actuating the unlocking device (13; 48), wherein the unlocking units are accessible from outside the combing regions, in particular from at least one of the end surfaces (5), and an additional positive securing connection is provided for securing the bar tacks (9; 32; 32a; 42) on the basic body (2).

Description

technical field [0001] The invention relates to a circular comb of a combing machine for carding textile fibres. Background technique [0002] Combs / spinning reeds in the form of circular combs are known from published prior use in combing machines, in which at least one carding element is arranged on a base body, which engages the fibers to be carded. A comb with a plurality of combing elements along its entire circumference is called a circular comb. In this case, the effective carding area can occupy 78°, 90°, 111°, 180° of the circumference of the contour line of the comb. Circular combs are also known in which the entire contour line is occupied by carding elements such as needles, needle strips, wire sawtooth sections, comb teeth or saw blade punches. These carding elements, which are themselves preassembled, are also called positioners. [0003] The positioner has a plurality of saw blade stampings or toothed toothed discs arranged one behind the other in the direc...
