Abstract

The circular comb segment includes a base body 1 and several combing card clothings 3, 4, 5, 6, 7. The combing card clothings are sequentially attached to the base body one after the other in the circumferential direction, and the point of the card clothing is facing the base body. The front end is inclined in the direction of V. The clothing tip of the frontmost clothing 3 adjoining the front end V of the basic body 1 passes first through the combed fiber hair F and is therefore subjected to more wear and tear than the clothings 4, 5, 6, 7 large. The frontmost clothing 3 therefore has a greater wear and tear resistance than the clothings 4 , 5 , 6 , 7 arranged further behind the basic body. This reduces the wear of the frontmost clothing 3 and thus prolongs the service life of the circular comb segments in an inexpensive manner.

Description

Circular comb segments for attachment to the comber cylinder of the comber

The invention relates to a circular comb segment for attachment to a comber cylinder of a combing machine, with a base body and several segments attached to the base body one behind the other in the circumferential direction Combed card clothings, each with clothing points, which are inclined in the direction towards the front end of the base body.

This circular comb segment attached to the continuously rotating combing cylinder of the combing machine is used in the combing machine to comb out the fiber hairs held by the comb pincers on the circular comb segment. . In this way, in particular the tip of the clothing which adjoins the front end of the basic body and passes through the fiber hair is firstly subjected to a certain degree of wear and tear. The wear of these frontmost clothing points can be particularly severe, because the fiber hairs that are passed through first by these clothing points still contain impurities and neps at this moment, and the degree of parallelism of the fibers in the fiber hairs Less parallelism during piercing than the clothing tips located further behind the basic body. The wear of the foremost clothing tips gradually leads to a change in the combing operation. Finally, the circular comb segments must be replaced.

The object of the present invention is to increase the service life of the above-mentioned circular comb segments.

This object is achieved with the circular comb segment of the present invention, which is characterized in that at least a part of the forwardmost combing clothing adjacent to the front end of the base body is more wear-resistant than the comber at a rearward position. The height of the clothing.

Higher wear resistance can be achieved, for example, in that the foremost combing wires consist of high-strength steel and/or are surface-treated or coated.

Efforts and costs to increase the wear resistance of the carding clothings at a later position on the basic body are not justified, since, as already mentioned above, the wear here is always lower.

The drawing shows an embodiment of the invention. The figure is a schematic vertical section through a circular comb segment attached to a combing cylinder of a comber.

The circular comb segment shown in the figures comprises a base body 1 which is attached to a combing cylinder 2 of a combing machine by means of fastening screws (not shown). During operation, the combing cylinder 2 rotates continuously clockwise around its axis shown in the accompanying drawings. On the outer circumferential surface of the basic body 1 having the shape of a cylinder segment, five combing clothings 3 , 4 , 5 , 6 and 7 arranged one behind the other in the circumferential direction are attached. They are, for example, tightly glued and sealed. The combing clothing is provided with clothing tips inclined in the direction towards the front end V of the basic body 1 with respect to the radial direction.

The fiber hair combed out is left on the rotating circular combing segment by comb nippers 8 pincers. The clothing tips of the foremost carding clothing 3 adjacent to the front end V of the basic body 1 are the first to pass through the fiber fluff that is continuously combed during the operation of the comber. When the fibers in the fiber fuzz are not relatively aligned and the fiber fuzz still contains impurities and neps, the clothing tips of the foremost combing clothing 3 experience a considerable amount of wear. That is why, according to the invention, at least a part of the foremost combing clothing 3 , for example the tip of the clothing, has a higher wear resistance than a combing clothing located further back from the front end of the base body 1 . With the exception of the foremost clothing 3, all clothings 4, 5, 6, 7 are for example made of the same steel. In this way, the foremost combing wires 3 consist of high wear-resistant steel, or are surface-treated or coated with a wear-resistant coating.

It is advantageous if the combing clothings 4-7 are attached to the base body 1 with detachable fastening means (not shown). In this way, individual clothings can be replaced according to the degree of wear and tear.
