In recent years, carding machines have become significantly faster and more efficient, allowing more fiber to pass through per unit time, and increasing the opening force of the cylinder wire between the cylinder tops, which is the main part of the carding process. For this reason, metallic wires are being developed that have a working angle and a number of needle heads that will not cause clogging with seed and leaf debris. Conventional top clothing, which is compatible with the strong opening force of the cylinder wire, has a flat or elliptical cross-section, and has a large radius at the front and rear ends in the direction of carding, and has a needle head. Even if the number is increased, the small fibers being combed are not sufficiently captured at the tip of the needle tip, and many small fibers pass through without receiving sufficient combing action, which causes neps. .

In addition, in order to improve the above-mentioned drawbacks and obtain top clothing with excellent fiber opening force, as shown in Japanese Patent Publication No. 54-26610, the cross-sectional shape of the clothing wire is changed from the tip to the back in the direction of action of the needles. 0.1~ for the sharp edge part
It has been proposed to form a rhombic wire with a radius R of 0.01 mm and four flat or concave surfaces.

Top clothing needle-planted with such diamond-shaped clothing wire has a greater fiber gripping force than conventional track wire or elliptical wire, and when the fibers are subjected to combing action, they can be sufficiently stretched and separated. It became.

However, when this needlework wire with a diamond-shaped cross section is planted on the base fabric, as shown in Fig. 4, the needlework wire 1
Since the acute angle part of the diamond-shaped cross section of No. 2 is placed in contact with the back surface 11 of the base fabric, the seating of the needle is unstable, and as a result, it is easy to cause needles to be raised and random stitches, and the performance of the top clothing is significantly reduced. Therefore, it cannot withstand use,
There is a problem that the lifespan is shortened.

The present invention solves the above-mentioned problems by changing the cross-sectional shape of the clothing wire, which affects the performance of top clothing, by incorporating the advantages of the conventional flat, elliptical and rhombic shapes, thereby improving the opening property and dust removal ability. The purpose of the present invention is to provide top clothing with further improved properties.

In the present invention, the radius of curvature R1 of the tip and rear ends of the needle in the long axis (action) direction is small and sharp, 0.03 to 0.07 mm, and both ends in the short axis direction form planes parallel to each other. Both ends (four places) of the surfaces are connected by a curve R2 whose radius of curvature is larger than R1, and the four surfaces connecting both ends of R1 and R2 are connected by a straight line indicated by a dotted line or by a curve R3 having a bulge on the outside. The present invention was solved by providing a top clothing in which a clothing wire formed in a substantially hexagonal cross-sectional shape is needle-planted in an elastic base fabric having a rubber layer as a base layer.

The cross-sectional shape of the needle is designed to best stabilize the base fabric during top bar clipping, making it difficult for needles to be raised, random needles, and the accompanying roughness of the needles (uneven needle heights) to occur. Furthermore, by making the radius of curvature of the leading and trailing ends as small as possible in the action direction (long axis) of the needle, the grip of the fibers is ensured, and the efficiency of fiber opening and dust removal is improved.

Furthermore, as shown in Fig. 3, the tip 7 of the doglegged needle
The needle shape is 8, the side surface is polished 9, and the diameter P of the needle tip at a distance (m) of approximately 0.5 mm directly below the tip is 0.1.
The needle tip is ~0.2mm sharp and sharp, and the hardness of the tip is increased to 760~900Hv by heat treatment, and the softening point is set as much as possible approximately 2~5mm from the tip of the needle above the waist 10 of the needle. I set it to a position between the needles and brought it close to the needle tip.

In addition, if the radius of curvature R 1 of the tip and rear ends in the direction of action of the needle is less than 0.03 mm, the tip part where the fibers receive the combing action will be sharp, which will cause a large bending stress on the fibers and prevent them from passing through the card. Residual stress remains even after the sliver is formed, causing the fibers to become curled, and furthermore, the tensile force of the carding action is added to the bending stress, resulting in fiber breakage, which is undesirable.

Also, if the radius of curvature R1 exceeds 0.07 mm, high speed
Under high production conditions, small fibers are not sufficiently captured at the tip of the needle tip, and a large number of small fibers pass through without being sufficiently carded, which is undesirable because it causes neps.

In addition, both ends of the needle in the short axis direction are parallel to each other, so that the needle is set in a range that best fits the base fabric during top bar clipping, provides stability, and prevents needle raising due to rattling.

In addition, both ends following the parallel planes are connected by a smooth curve R2, and the four sides connecting R1 and R2 are connected by a straight line or a curve R3 with a bulge on the outside to form a cross-sectional shape, so there is resistance in the direction of action of the needle. The combing performance is further improved because of the streamlined shape.

By having the above-mentioned structure, the present invention can sufficiently withstand the strong bending stress generated between the cloths of the carding machine, grip the fiber group to be combed at the tip of the needle in the action direction, spread it, and cut it. It is formed with a radius of curvature R1 that does not cause
Since the surface is formed as a straight line or a curved line R3 with an outward bulge, the fibers interacting with the metallic clothing on the cylinder gripped at the tip can move along the sharp straight line or smooth streamlined outer periphery without generating large bending stress. As a result, fibers are opened and fibers do not break.

In addition, the U-shaped needle sits well and stably on the base fabric, and there is no wobble that can cause needle raising or random needles, which prevents shortening of life caused by needle raising or needle touching accidents. Lifespan is extended.
