Abstract

PURPOSE:The titled half lap having hardly gaps in the vertical direction, wherein a laminate of spike board can be simply inserted, securely kept, channels can be easily processed by an end mill, obtained by engaging the channels having compressed parts with the laminate of spike board. CONSTITUTION:The plural channels having compressed parts in the axis direction 10 are bored in the main body 1 of cylinder half lap, and the four corner parts 21 and 22 of the compressed parts are slanted. Plural sheets of the spike boards 16 having the pin base parts 12 having the pin heads 11 with the working angle alpha at the top and the pin insertion parts 13 are laminated and fixed to form the laminates 18 of the spike board. The laminates 18 of the spike board are inserted and laminated in the plural channels 10 of the main body of the cylinder half lap.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure of a cylinder half flap for a comb.

As shown in the first leap, the conventional cylinder half flap for combing has a groove 2 in the cylinder half flap body 1 in the radial direction of the cylinder and a small groove 3 in the diagonal direction, and a throat plate with a needle head 4. 5 &1.1Q.

A needle row ribbon 8 formed by fixing a band-shaped metal plate 6 to a dovetail groove 7 provided on the side surface of the needle plate is inserted into the groove 2 and arranged in a row. Note that the protrusion 9 provided on the side surface of the throat plate 5 engages with the small groove 3.

In the above-mentioned combed cylinder half-wrap, the degree of engagement between the groove 2 and the needle row ribbon 8 is double r), and there is no gap.
1. "It must be easy to insert the cutlet when it is inserted. However, when the fibers are subjected to the combing action by the needle head 4, the component force F'1 acts in the direction of pulling out the F row ribbon 8 from the groove 2, and the gap lTl1 Because of this, there is a drawback that the gap between the groove 2 and the needle row ribbon 8 becomes large after long-term use due to the deformation caused by the impactful repeated stress. As a result, the needle row ribbon 8 is formed, but since the position where the metal plate 65 is inserted and fixed is on the side of the needle plate, the needle row ribbon is curved in the horizontal direction (7). The repulsive force is the force that holds the needle row ribbon in the groove, and the resistance during insertion is large.The gap between the pronged needle row ribbon and the I-shaped hole causes uneven protrusion of the needle heads in the radial direction. There is also a drawback.

X '3 filg) The combed cylinder half-lap solves the drawbacks of conventional a] described above, and an example will be described below based on FIG. FIG. 2 is a cross-sectional view of a main part showing an example of a cylinder half-lap for use in the present invention.

The cylinder 11 cylinder half flap body 1 has the cylinder circumference equal to [
A plurality of ++W 10s having constricted portions in the direction of the portions are bored while maintaining a distance from each other. The four corners of the constriction of the tenth sign 2
1 and 22 are inclined at a certain angle (for example, 45°).

Next, it consists of a needle base 12 having a needle head 11 with a working angle α in the direction of cylinder rotation on the upper part, and a needle insertion part 13 having a constricted part. A throat plate 16 is formed by providing a slit 15 communicating with the hole 14.

The four corners of the constricted portion of the needle insertion portion 13 of the throat plate 16 are sloped so as to contact at least one corner of the iR10 of the cylinder half flap body 1, and the needle A gap is provided between the lower part of the insertion part 13 and the lower part of the insertion part 13.

Note that there is a gap 2 at the corner 22 at the front of the top (groove 10σ).
3 - this gap 1iiJ 23 can also be provided at other corners.

Needle head 1 of the throat plate adjacent to the throat plate 16 in the cylinder axial direction
1 are laminated so as to be alternately shifted in the direction of cylinder rotation and arranged in a staggered manner, and a continuous member 17 made of metal or synthetic resin is fitted and fixed in the slit 15 of the throat plate. The throat plate laminate 18 is formed as shown in FIG.

A cylinder for combing of the present invention is produced by inserting and arranging the two-part draw plate laminate into the plurality of grooves 10 in which the cylinder half-wraps are continuous.
Create a flap.

In addition, needle base F? If the rotating portion 19 is provided so that the upper part of the side 1 in the cylinder rotation direction contacts the needle plate adjacent to the cylinder rotation direction, but the lower part does not, the needle plate 18 can be easily installed in a row. ;
b.

In addition, other examples of the 41st M fa) fb) rcl Ic needle plate 16 are shown, and (a) shows that 14 holes are provided in the needle base 121, and a hole 20 is also provided in the lower part of the needle insertion portion. At first glance, several needle plates are laminated with a slit 15, and by inserting resin into the hole 14.20 of the needle plate or the hole 14.20 and the slit 15, they are fixed to form a continuous body. This constitutes a plate laminate. (b) shows that the lower part M of the slit 15 is narrower than the lower part of the slit 15, and by lowering the diameter of the body connected to the slit, the rigidity can be made stronger. (C) shows the hole 14 having a rectangular cross section, and the adhesion of the laminate is stronger.

Also, 1, the 11-zozo shape is a diagonal, a quadrilateral, etc. σ) Various σ)
It can be made into any shape.

The connecting body 17 that fits into the holes 14 and 20 and the slits 15 is made of a metal block, metal plate, synthetic resin, or a metal rod embedded in a synthetic resin, and is inserted into the hole from the longitudinal direction. Or at the right angle (・) insert the sword-#Q
This forms a laminate.

In addition, synthetic resin or adhesive may be poured, welded, or these may be used in combination with the plate.The gap 1 between the groove 10 of the half-wrap body and the throat plate laminate 18 in the downward direction is 0. .05- or less, the lateral gap may be less than a O5fi, and the part where the groove of the cylinder honey flap body and the needle i alluvial layer are kept in contact with each other is at least 3.
By holding the throat plate laminate at two positions, the insertion resistance due to the 29 dimension and processing error of the throat plate fii layer is released into the gap 23, and the throat plate laminate can be held easily and reliably.

By the way, in the above-mentioned Example t, the corners of the constriction part are all 45 degrees, but this angle is selected as appropriate), and -I: the corner part and the corner part It is possible to make the fr1 degrees of the two different degrees.

Thursday '573 l! The II-1-ma L11 shilling half-wrap has the above configuration (・), the throat plate laminate is fitted into the groove with the constriction, and there is almost no gap in the H-force direction. , or needle plate size 1? It is easy to insert the body (can be held at 6A, and the grooves are symmetrical and can be easily machined with an end mill), and precision is not required. FiK is about 11 (low, you can feel the machining error.

In addition, the needle 117 m Ffi body 1iil! The design is located approximately at the center of the throat plate, so there is no need for the needle to curve left or right, making it easy to insert into the groove of the half-wrap body, etc. (7) Excellent effects. This is an invention that has
