Description

[Detailed Description of the Invention] The present invention relates to the configuration of metallic wire used in a carding machine.

The metallic wire 1 for the carding machine is conventionally shown in Fig. 1A.

As shown in the mouth, it was composed of a single metal, and the tooth body 2 and the base body 3 were integrally constructed.

FIG. 2 is a sectional view of the main part of the carded cotton when the metallic wire 1 is wound around the drum 4 of the carding machine.

The lateral pitch a of the metallic wire 1 is an element that plays an important role in the opening action of the carding machine, but with conventional metallic wires, it has been impossible to change the lateral pitch after forming the tooth shape. .

That is, depending on the type of fiber, spinning conditions, etc., it is necessary to use several types of metallic wires with different transverse pitches a even though they have the same tooth profile.

In addition, when alloy steel is used to maintain the wear resistance of the metallic wire, the metallic wire base 3, which does not require wear resistance, has an integral bottom shape, which is expensive, and furthermore, forming the bottom into the above shape requires processing. It was extremely difficult.

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

FIG. 3A is a side view showing one embodiment of the metallic wire of the present invention.

A base body 6 made of a square wire made of mild steel and having a groove in which a metallic wire body 5, in which flat wires made of alloy steel are arranged vertically and the upper part is punched and formed into a serrated shape, is fitted into the lower part of the metallic body.
It is fitted into the body and fixed by welding, resin coating, etc.

The longitudinal section of the metallic wire body can be a rectangular trapezoid, a right trapezoid, etc., and the thickness a of the base body can be selected as desired depending on the spinning conditions.

Additionally, wear-resistant materials that cannot be rolled into the shape of conventional metallic wires can be used for the metallic wire body.

FIG. 3 is a side view showing another embodiment of the metallic wire of the present invention.

A square wire 7 made of synthetic resin is fixed by welding, resin coating, etc. to both lower surfaces of a metallic wire body 5 in which flat wires made of hard steel are arranged vertically and the upper part is punched out and formed into a serrated shape.

Since the present invention is constructed as described above, it is possible to arbitrarily select the lateral pitch, which is important for the carding action, which further enhances the opening action in the carding machine, and also improves the abrasion resistance compared to the conventional method. It is now possible to reduce material costs, and because the edges made of square wire made of mild steel or synthetic resin are made to protrude from both sides of the metallic wire of the alloy steel flat plate, it is possible to reduce the material cost. It is an excellent invention with practical effects such as being able to be used as a wire and easily winding it onto a drum.
