Description

[Detailed Description of the Invention] Conventionally, a needle element with one end pointed is fixed to the inner surface of a metal strip with a spot weld with the tip of the needle element facing downward, thereby producing a large number of needle elements. The needle body is constructed by fixing the needle bodies to a metal strip and bending the intermediate portions of these needle bodies into a V-shape so that the tip side half of each needle body faces outward and diagonally upward. However, the manufacturing method of the squid square needle, in which the needle body is attached to the squid horn by irremovably winding a metal strip around a rod-shaped attachment part provided on the squid horn, was developed in 1973.
This is known from Publication No. 5030, etc., but since these needle bodies are attached one by one to a metal strip by brazing or the like, the manufacturing work is complicated and has the disadvantage of inefficiency. Ta.

The present invention provides a method for producing squid horn of this type, which includes:
The purpose of this method is to remove such defects by folding a wire with sharp ends in two to form a U-shape, and then folding the middle of the two sides of the two-fold body into a U-shape. A series of two needle bodies are formed by bending the needle bodies, and one point on each of the two vertical sides of this needle body is connected to two points on the inner surface of the metal strip with the tip of the needle body pointing in the radial direction. The needle body is formed by fixing it with a spot weld in the facing state, and the metal strip of this needle body is irremovably wound around the rod-shaped attachment part provided in the squid corner, and the needle body is attached to the squid corner. The gist of this is that

In the illustrated embodiment, a wire with sharp ends is folded in half to form a U-shape, and the middle of the two sides of this bifold body 1' is further bent into a V-shape to form two wires in a row. constitutes a needle element body 1, and this needle element body 1
One point on each of the two sides of the vertical part 2 is fixed to two points on the inner surface of the metal strip 3 by a spot weld 5 with the needle tip 4 of the needle body 1 facing in the radial direction, thereby forming a large number of needles. A needle body 6 is constructed by fixing the element body 1 to a metal strip 3 at intervals, and the metal strip 3 of this needle body 6 is irremovably wound around a rod-shaped attachment part 8 provided on a squid horn 7. This is completed by attaching the same needle body 6 to the squid horn 7.

As described above, the present invention has both ends sharp and the middle of the two sides of this bifold body is further bent in a V-shape to form a series of two needle bodies, and the needle bodies are perpendicular to each other. The needle body is constructed by attaching one point on each of the two sides of the metal strip to two points on the inner surface of the metal strip using a spot weld with the needle tip of the needle element facing in the radial direction. The two needle bodies can be fixed to the metal strip at once, making it extremely efficient to attach the same needle body to the metal strip.In addition, this needle body has a U-shape. Since it is composed of two pieces in series, it is sufficient to fix it to the metal strip by spot welding two points facing each other to two points on the inner surface of the same metal strip. Two-point nails cannot be attached to a metal strip with solid strength unless the long base end of the one-nail type is fixed to the metal strip by brazing or the like. Each fishhook can be firmly attached to the metal strip by this simple process, and these not only have the effect of reliably achieving the above-mentioned object of the present invention, but also have the effect that the metal of the needle body can be firmly attached. Since the needle body is attached to the squid corner by irremovably wrapping the strip around the rod-shaped attachment part provided at the squid corner, even if there is variation in the thickness of the rod-shaped attachment part, the variation will not be caused by the variation. The winding diameter of the metal strip can be changed, and the needle body can be fixed to the rod-shaped attachment part for one-size-fits-all use.
