Problems solved by technology

In practice, however, it has been shown that in many cases a torque wrench is not used and these screws are tightened with a simple wrench, leading to the above mentioned risk of tightening the screws with a higher than specified torque
This can lead to the described deformation of the comb, which can adversely affect the distance to be maintained between the lower nipper and the tooth tips
In the worst case, this can lead to a collision between the tooth tips of the cloth and the lower nipper

Embodiment Construction

[0034] figure 1 A circular comb 1 is shown having a circular comb shaft 2 on which two flanges 4 are mounted at a distance from each other in a rotationally fixed manner. This also from figure 2 based on the figure 1 This is especially evident in the detail view X of . A base body 5 is fastened to part of the circumference of the flange 4 and, on its circumferential surface U, the base body supports a plurality of comb elements K1 to K4 positioned one behind the other. In the present example, the comb elements K1-K4 have holding bars H1-H4 to which the clothing elements G1-G4 are respectively fastened. The clothing elements G1-G4 can be fastened to the respective holding bars H1-H4 via laser welds, for example as shown and described in published EP 2650414 A1. However, other types of fastening are also possible.

[0035] An exemplary embodiment of the fastening of the front comb element K1 according to the invention is in figure 1 shown in , and in image 3Shown in enl...

Abstract

The invention relates to a circular comb of a combing machine, comprising a base body, a comb element, a retaining element, and a bolt-shaped fastening element. The first end section of the fastening element protrudes into the retaining element, and an adjoining middle section protruding into an opening in the base body oriented radially with respect to the circular comb. A second end section adjoins the middle section of the particular fastening element and is supported on a support surface of the base body in the area of the opening, the second end section extending at least partially beyond the cross-sectional area of the opening. The middle section of the fastening element bears one spring element, which with a first end is supported on a support surface of the second end section of the fastening element facing the middle section, and with its second end is supported on the oppositely situated support surface of the base body, and the retaining element has a detent point for the first end section of the fastening element, into which the first end section of the fastening element is transferable by a longitudinal displacement of the fastening element by overcoming the elastic force of the spring element.

Description

technical field [0001] The invention relates to a circular comb for a combing machine according to the preambles of claims 1 and 5 . Background technique [0002] A design is known from DE 33 36 876 A1 in which the comb element for a circular comb consists of a plurality of toothed segments provided with toothed clothing and held together by longitudinal bolts . Longitudinal bolts protrude into holes provided in the toothed segments. A plurality of comb elements (also called bars) arranged one behind the other form a comb segment with a closed combing surface. A toothed segment of a particular comb element is provided with a dovetail shaped groove via which said toothed segment is connected to the base body of the circular comb by means of a holding member. The holding member is provided with a corresponding dovetail-shaped counterpart profile via which it engages with a groove in the toothed segment and is held in a corresponding groove in the base body via a screw conne...
