Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method of manufacturing a tape electric wire.

(Prior art) The conventional method for making tape electric wires is the Japanese Patent Publication No. 55-493.
The one described in Publication No. 61 is well known.

This is a method in which two square holes are provided at arbitrary locations in the longitudinal direction from both sides of multiple conductors arranged in parallel in the longitudinal direction.
This method is characterized by the process of sending out a sheet of insulating film and pasting the insulating film so that each square hole is aligned.

After this, the square hole is cut at the center, and the ears at both ends in the width direction are cut off to form the insulating part 14 as shown in FIG.
It is lifted up so that the conductor W is exposed from both ends.

(Problem to be solved by the invention) However, when using this method, the insulating tape on both sides of the conductor is separate, so there is a drawback that the square holes are misaligned. There is a drawback that the deviation in direction gradually increases, and a situation may occur in which the square holes no longer match.

(Means for Solving the Problems) This invention was made to eliminate the above-mentioned drawbacks, and in order to completely eliminate the mismatch of square holes, one insulating film is folded to form two films. The feature is that a square hole is bored there, and specifically, it includes a step of making a perforation at the center position in the width direction while feeding out a tape-shaped insulating film in the longitudinal direction, and a step of making a perforation at the center position in the width direction of the insulating film at the perforation. A step of folding the insulating film in half and stacking it up, and drilling square holes at desired intervals in the longitudinal direction, and expanding the insulating film again into a single sheet and placing a predetermined number of conductors on one half of the film parallel to each other in the longitudinal direction. The process of tacking along with the
The present invention provides a method for manufacturing a tape electric wire, which is characterized by a step of folding and fusing the other half of the insulating film onto the half to which the conductor is temporarily attached.

(Function) Since one insulating film is folded from the center in the width direction to form two layers, and the square hole is drilled in the two layers of insulation film, the deviation in the longitudinal direction of the square hole is will never occur.

(Example) The invention will now be described in detail with reference to FIG.

If the width including the ears of the tape electric wire that is the product is a, then
An insulating film 1 having twice the width 2a is sent out by a delivery roll 2, and a perforation m provided at the center position in the width direction is provided by a roller 3 to form a perforation m extending in the longitudinal direction.

A pair of folding rolls 4 having an axis perpendicular to the axis of the delivery roll 2 are provided downstream of the roller 3, and in this folding roll 4, the insulating film 1 is folded at the perforation m. Can be folded into sheets.

A pair of presser rolls 6 whose axial directions are parallel to the folding roll 4 are provided downstream of the folding roll 4 and appropriately spaced apart from each other. In this case, the insulating film 1 travels while being held in a folded state.

However, a perforation device 5 is provided between the folding roll 4 and the presser roll 6, and this makes rectangular square holes 7 of an appropriate size at an appropriate pitch interval in the two-ply insulating film 1. drilled.

The drilling device 5 includes, for example, a hole punch 5 as shown in the figure.
Similar to 1, female molds 52 are arranged oppositely on both sides of the insulating film 1, and the reciprocating device 53 advances downstream at the same speed as the insulating film 1, and quickly returns after drilling is completed. This is a configuration that provides movement.

The punching device 5 is not of the punching type as shown, but may be of another type, such as a rotary cutter.

Downstream of the holding roll 6, the axial direction is the delivery roll 2.
A pair of pinch rolls 8 identical to those shown in FIG.

The plurality of conductors W are sent out from the conductor sending device 9,
Immediately downstream of the pinch rolls 8, it is attached onto one of the folded halves IA, and then tacked by the rolls 10.

Next, the creasing roller 11 is applied to the perforations m of the insulating film 1 to make it easier to fold, and then the Ikekata half-fold half IB is folded into the same IA by the overlap fusing roll 12 whose axis is parallel to the axis of the presser roll 6. Fold over and fuse.

After that, the insulating film 1 is cut along the cutting lines AB and CD passing through the center of the square hole 7 and orthogonal to the longitudinal direction of the insulating film 1, and the ears 13 and 13 on both side edges are cut off. Electric wires can be replaced.

(Effects of the Invention) According to this invention, one insulating film is folded from the center in the width direction to form two layers, and the square hole is bored in the two layers of the insulating film. , there is an effect that no displacement occurs in the longitudinal direction of the square hole.
