Abstract

PURPOSE:To increase the production speed of linear member considerably while maintaining the quality of taping by winding a plurality of tapes sequentially in longitudinal direction of linear member with same winding angle. CONSTITUTION:Two sheets of tapes 1a, 1b having same construction are arranged alternatively over the outercircumference of a linear member 2 with same winding angle theta, and wound while butting the edges. In other word, each tape 1a, 1b is wound spirally with same taping pitch P1 and arranged in a gap G1 formed by said tapes 1a, 1b. Here, each tape 1a, 1b is wound simultaneously into said shape. While said tape 1a, 1b is wound simultaneously into said shape. Each tape 1a, 1b has predetermined tape width W1 and when winding over a linear member 2 having the outer diameter D, predetermined width WA1 is formed longitudinally over the linear member 2. Consequently, the production speed of the linear member 2 can be improved considerably while maintaining the quality of taping.

Description

DETAILED DESCRIPTION OF THE INVENTION [Background and Objectives of the Invention] The present invention relates to a tape winding method for winding a tape around a linear material.

Conventionally, when a tape winding layer is formed by winding a long tape around a wire material, as shown in FIG. θ, and is helically butt-wound, slightly overlap-wound, or gap-wound around the wire material 2. FIG. 1 illustrates the case of gap winding.

The manufacturing speed (■) of the linear material 2 on which the tape winding layer is formed in the shape of any of the above examples is determined by the taping pitch P and the rotation speed M of the tape winding machine (taping head), and is determined by the following (1).
) is expressed by the formula.

V=PxM (m/min) (1) Furthermore,
The taping pitch P depends on the tape width W used, and the number of revolutions M of the taping head depends on the mechanical strength of the tape and the taping head, respectively.

Under such conditions, in order to further improve the manufacturing speed (1) of the wire material, either the taping pitch P should be set large, or the number of revolutions M of the taping head should be increased. When the taping pitch P is set large, it is necessary to use a wide tape, but a wide tape affects the bending resistance of the linear material. In addition,
The maximum tape width that can be used for wrapping is limited by the tape wrapping machine. On the other hand, the number of rotations M of the taping head
is particularly limited by the mechanical strength of the device, and in order to increase this it is necessary to introduce a new device, which requires a large amount of expense.

For the above reasons, it was impossible to dramatically increase the manufacturing speed of the wire material using the existing equipment and maintaining the quality of the tape-wrapped layer after wrapping. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a tape winding method that eliminates the drawbacks of the prior art described above and can significantly improve the manufacturing speed of a linear material on which a tape winding layer is formed.

[Summary of the invention]

That is, the above object of the present invention is to provide a tape winding method for a wire material by spirally winding the tape around the outer peripheral surface of the wire material. This is achieved by a tape winding method for a wire material, which is characterized in that the wire material is repeatedly arranged and wound in the longitudinal direction of the wire material at an angle.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained in detail with reference to FIG. Note that 1. The same reference numerals are used for the same components as in the conventional example shown in FIG.

In FIG. 2, two tapes la and lb having the same configuration are alternately arranged on the outer peripheral surface of the wire material 2 with the same winding angle θ,
It is butt-wound with the edges touching each other. That is,
The first and second tapes Ia and lb are spirally wound with the same taping pitch P1, and are located between the gaps G1 formed by the respective tapes. Furthermore, both tapes la,
lb is wound in the above-mentioned shape by simultaneous winding operation. Both tesos la and lb each have a tape width W1, and when wound around a wire material 2 having an outer diameter, a constant width WA in the longitudinal direction of the wire material 2 (hereinafter, in this specification, This width is called the effective width.)

If the maximum usable tape width according to the prior art is W, the taping pitch when using that tape is J), and the effective width is WA, then the tape width W1 that can be used in the present invention is:
The maximum value is WA, = WA, and the above (2
) is the optimal tape width. In addition, the taping pitch pl is P1 = WA work X 2 + G X 2 (
3). However, in the above equation (3), the gap G f
d is calculated as zero since this example is butt wound.

When the tape-wrapped layer is formed as described above [7], the manufacturing speed of the linear material according to the present invention (1) is as follows: v, = P, X M (4 ). (M: Number of rotations of the taping hen l?) Here,
If the number of tapes to be wound at the same time is N, the taping pitch p is expressed as P, = NXP (5). Therefore, the manufacturing speed of the linear material according to the present invention ■1 can be calculated from equation (4). , V,=NxPxM=NxV (6)
The number of tapes that can be wound at the same time can be doubled.

Although the present invention has described the case of butt winding in the above embodiments, one roll of O-ζ-run or &-j-run of several percent to several tens of percent of the tape width used is It can also be applied to gap winding. Also, the number of tapes to be wound simultaneously is not just two,
It is possible to install three or more.

〔Effect of the invention〕

As described and traced above, according to the tape winding method according to the present invention, a plurality of tapes can be used simultaneously (7.
The winding speed can be greatly improved. Also,
In implementing the present invention, the cost of modifying existing equipment is as follows:
Approximately 1/30% lower than when introducing a new tape winding device
It is 10 or less.
