Description

[Detailed Description of the Invention] The present invention relates to the structure of a cylinder half flap for combing.

As shown in Figure 1, the conventional combed cylinder half-lap has grooves drilled in the cylinder axis direction of the half-lap.
A needle row ribbon consisting of pins or throat plates fixed in parallel was installed by inserting it in rows, but this had the disadvantage that if the needles were damaged by fiber lumps, impurities, foreign objects, etc., the entire needle row ribbon had to be replaced. .

In particular, damage to the needles in the circumferential direction of the cylinder is common, but in such cases, even if some of the needles in the axial direction of the cylinder are damaged, it is necessary to replace several needle row ribbons.

The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to the drawings.

Example 1 One embodiment of the present invention is shown in Fig. 2, A-9.

Dovetails 2 are provided protrudingly on the half wrap 1 in the axial direction of the cylinder at appropriate or unequal intervals, and the dovetails 2 have one or more needle heads 3 on the upper part, and dovetail grooves on the lower part that fit into the dovetails. A throat plate 5 provided with a needle plate 4 is fitted, a plurality of throat plates are arranged in parallel, and both ends of the throat plate are fixed with side plates 7 to form a combed cylinder half-wrap.

The dovetail may be formed integrally with the half-wrap, or the throat plate may be fitted and fixed to a separately manufactured dovetail and then screwed to the half-wrap.

In order to make the fit between the dovetail and the throat plate tighter, a split 8 or a liner 9 may be provided as shown in Fig. 3, B-9.The throat plate may have a coarser number of needle heads on the side where the fibers first act. It is better to change the needle heads so that the number of needle heads becomes progressively denser, and it is also possible to insert a spacer plate between adjacent needle plates on the side where the number of needle heads is coarse.

If the needle is damaged due to the above configuration, remove the side plate, remove only the damaged needle plate, and re-insert it to refill.
It can be easily replaced.

In addition, by appropriately adjusting the number of needle heads on the throat plate and the spacing in the axial direction of the cylinder, the total number of needle heads can be optimized depending on the type of fiber to be combed.

Example 2 Another embodiment of the present invention is shown in FIG. 4A.

Dovetails 2 are provided protrudingly on the half wrap 1 in the circumferential direction of the cylinder at appropriate or unequal intervals, and the dovetails 2 have one or more needle heads 3 on the upper part and fit into the dovetails on the lower part. Insert the throat plate 5 provided with the groove 4, and insert an appropriate spacer piece 6 between adjacent throat plates.
are inserted, a plurality of throat plates 5 are arranged in parallel, and both ends of the throat plates are fixed with side plates 7 to form a combed cylinder half-wrap.

The combing effect can be made most favorable by gradually increasing the number of needles on the needle plate on the side where the fibers first act.

Since the present invention has the above-mentioned preemption, even if the needle is damaged, it can be easily replaced.

In particular, if the cylinder is damaged in the circumferential direction, having circumferential dovetails as in the second embodiment makes it easier to replace only the damaged part.

Also, since the needle is fitted with a dovetail groove provided with a split or liner, the precision of the needle can be increased.

Furthermore, since the throat plate can be inserted using the dovetail as a guide, the cylinder bar flap can be easily assembled and automated.

In addition, since the cylinder bar flap of the present invention is divided into many parts, the needle head density can be easily changed to suit the type of fiber, which has great practical effects.
