This continuous take-up tool such as a crimp terminal is a long take-up tool such as a continuous continuous crimp terminal configured by a pair of left and right collar bodies and a take-up tube provided between the collar bodies. The inner liner of the corrugated cardboard collar formed of the liner and the corrugated flute has a groove width that matches the diameter of the paper tube take-up cylinder, and has a depth that does not reach the intermediate liner, and a wavy shape that crushes the inner surface of the groove. An annular groove provided with elasticity by the flute and the inner surface liner is provided, and a winding cylinder having adhesive on both ends is fitted into the annular groove so that the groove bottom of the annular groove is formed by the elastic restoring force. This is a structure in which the end portion of the take-up cylinder is pressed and adhered.

This winding tool is made of corrugated cardboard in which an inner liner is formed with an annular groove having a groove width corresponding to the wall thickness of the winding tube, and a winding tube having an end coated with an adhesive. Is used to form a take-up tool having an H-shaped cross section, which is fitted into the annular concave grooves of the collar plate corresponding to both ends of the take-up cylinder. The long continuous crimp terminal etc. produced by the above is wound to prevent collapse of the crimp terminal wound by the left and right collar bodies, but this winding tool is provided with an inner surface liner and The elastic restoring action of the wavy flute and the fitting in the groove and the joining with the adhesive provide a firm attachment of the collar body.

[0004]

However, both ends of the winding cylinder in the above-mentioned winding tool are simply vertical cut ends, and after applying the adhesive to the ends as they are, they are fitted into the annular groove. Since it is only bonded and bonded, the application area of the adhesive to the take-up cylinder that uses a relatively thin paper tube is narrow, and the amount of application is small, so a take-up tool with a stronger adhesion of the collar body is obtained. However, since the vertical cut end portion cannot be easily fitted into the annular groove, the efficiency of the assembling work cannot be improved.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned conventional problems, and an object of the present invention is to dispose paper on the inside of a corrugated board made of corrugated cardboard, which is formed by inner and outer double-sided liners, intermediate liners and corrugated flutes. A tube receiving portion having a diameter matching that of the tubular winding tube is provided, and a corrugated cut end portion is formed in the tube receiving portion. The purpose of the present invention is to provide a winding tool such as a continuous crimping terminal for increasing the amount of adhesive to be adhered to the corrugated cut end to strengthen the adhesion of the collar body and to easily fit it into the tube receiving part. .

[0006]

Means for a winding tool such as a continuous crimp terminal according to the present invention for achieving the above-mentioned object is provided by a pair of left and right collar plates and a winding means provided between the collar plates. In a winding tool such as a long continuous crimping terminal composed of a tube, inside the corrugated board made of corrugated cardboard formed by the inner and outer double-sided liner, the intermediate liner and the wavy flute, the diameter of the paper tube Adopting a matching tube receiving portion, forming a corrugated cut end portion on the cylindrical receiving portion, and fitting a winding cylinder with an adhesive to the corrugated cut end portion to form an adhesive in the winding cylinder. It is characterized in that the amount of adhesion to the corrugated cut end is increased.

Further, according to the present invention, the tube receiving portion has a groove structure, the groove width is adapted to the wall thickness of the take-up tube, the groove cut end is corrugated, and the depth is such that it does not reach the intermediate liner. An annular groove provided with elasticity by a wavy flute to be crushed and an inner surface liner is provided on the inner surface, and a winding cylinder having adhesive at both ends is fitted into the annular groove, and the groove bottom of the annular groove is formed by the elastic material. There is also a case where the return force of (1) causes the end portion of the take-up cylinder to be pressed against and adhered.

Further, the cylinder receiving portion is a plate-shaped plate body, and the peripheral end of the plate body is attached to the inner surface of the collar plate as a corrugated cut end portion, and the winding cylinder is fitted and adhered to the cylinder receiving portion to form the wave. In some cases, the adhesion of the adhesive to the cut edge of the shape may be increased.

[0009]

When the winding tool such as the continuous crimping terminal according to the present invention is used, a continuous long crimping terminal or the like is wound around the winding tube portion between the two collar plates, and the left and right collar plates are used. To prevent collapse of wound crimp terminals, etc., this winding tool is made of corrugated cardboard with a tube receiving part on the inner liner that matches the diameter of the winding tube, and adhesive is applied to the ends. A winding tool is formed by using a winding tube such as a paper tube. The tube receiving portion is used as a corrugated cut end portion, and the amount of adhesive applied to the corrugated cut end portion is increased to form a collar plate. It is possible to increase the amount of winding of the member to be wound by mounting firmly.
