リンダとトップ間を通過する単位時間当りの繊維の通過
量が多くなってきた。このため、シリンダのメタリック
ワイヤにおいては開繊力を向上させるため、働き角や針
頭数を変えたメタリックワイヤが種々開発されている。In recent years, carding machines have been remarkably speeded up and produced with high productivity, and the amount of fibers passing through between the cylinder and the top per unit time has increased. Therefore, in the metallic wire of the cylinder, various metallic wires having different working angles and the number of needle heads have been developed in order to improve the opening force.
従来、上記メタリックワイヤと組み合せて用いられる

トップ針布（18）が提案されている（特公昭54−26610
号公報，特公昭54−28491号公報）。Conventionally, as a top clothing used in combination with the metallic wire, as shown in FIGS. 6 (a) and 6 (b), the radius of curvature of the front and rear ends is 0.1 to 0.16 mm, and the short axis and the long axis are A top cloth (16) in which a needle cloth wire (14) having a substantially elliptical cross-sectional shape with a ratio of 1: 1.40 to 1.50 is planted on a base cloth (15) for a needle cloth, and FIG. 7 (a). , (B), an acute angle portion is formed at the tip and the rear end with respect to the action direction of the needle, and the needle cloth wire (17) having a substantially rhombic cross-sectional shape in which the four surfaces are flat or concave is attached to the needle cloth. A top needle cloth (18), which is a needle for the base cloth (15), has been proposed (Japanese Patent Publication No. 54-26610).
(Japanese Patent Publication No. 54-28491).

となっていた。However, the needle laying wire (1
In the top needle cloth (16) using 4), the tip and the back end in the carding action direction are formed with large radii of curvature, so that the small lump fibers to be combed can be captured by the tip of the needle tip. It became insufficient, and a large amount of small lump-shaped fibers passing between the cylinder and the top without being sufficiently subjected to the combing action, which was a cause of nep generation.
また、略菱形断面形状を有する針布線（17）を用いた
トップ針布（18）では、基布（15）に植針された針布線
（17）の座りが不安定となり、起針、乱針を生じ易く、
トップ針布（18）の性能が著しく低下するという問題点
があった。Further, in the top clothing (18) using the clothing wire (17) having a substantially rhombic cross-sectional shape, the seating wire (17) planted in the base cloth (15) becomes unstable in seating, and , Prone to random needles,
There is a problem that the performance of the top clothing (18) is significantly reduced.

したトップ針布（21）が考えられている。Therefore, in order to eliminate the above problem, as shown in FIGS. 8 (a) and 8 (b), the working direction of the needle, that is,
The radius of curvature R 1 at the front and rear ends in the major axis direction and the radius of curvature R 2 at the corners at both ends in the minor axis direction are in the relationship of R 1 <R 2 , and each of the above radiuses of curvature R 1 , R 2 A needle cloth wire (19) having a rhombic and elliptical composite cross-sectional shape in which four sides connecting the ends are connected to each other by a curved line with an outward bulge is planted on a base cloth (20) for a needle cloth. ) Is considered.

る。In the above top cloth (21), since the rhombus shape remains in the cross-sectional shape of the needle, the seating of the needle cloth wire planted on the base cloth becomes unstable and raises like the case of using the rhombus wire. Needles and random needles are likely to occur, and the quality of the sliver may deteriorate.
また、複合断面形状を有しているため、断面積が大き
くなり、磨針による針頭面積の変化が大きく、針布の寿
命が短かくなるという問題点がある。Further, since it has a complex cross-sectional shape, there is a problem that the cross-sectional area becomes large, the change in needle head area due to the brush needle is large, and the life of the clothing is short.
