Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a longitudinal tape spreading device in a take-up and rotation type cable twisting line.

As shown in FIG. 3 (top view) and FIG. 4 (side view), the conventional tape longitudinal attachment device is composed of a tape feeding device 13, a tape guide 14, an overlap die 15, and a forming tube 16. , the center line of the cable core 11 and the tape 12
Match the center line of the overlap die 1
5, the cable core 11 is wrapped with tape 12, and forming tube 16 is used to form the cable core 11 vertically.

Such tape longitudinal spreading devices are also used in take-up and rotation type cable twisting lines. However, in winding and rotation type cable twisting, the cable core 11 advances while twisting and rotating, so wrinkles are likely to occur at the ends of the tape 12. To prevent wrinkles, use overlapping dice 1.
5 and forming tube 16 must be selected strictly according to the outer diameter and type of cable core 11, and a large number of these must be prepared, which increases equipment costs and requires a lot of time and time for replacement. Requires manpower.

The present invention has been made based on the above, and aims to provide a tape longitudinal spreading device that can prevent the occurrence of wrinkles at tape ends even with extremely simple equipment.

The tape longitudinal attachment device of the present invention has a tape feeding device placed on a base, and the tape feeding device is rotatable in a plane parallel to the base surface and moves in a direction perpendicular to the cable core traveling direction in the plane. This feature is characterized in that it is configured to be possible.

An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 is a perspective explanatory view schematically showing the entire tape longitudinal application device, in which 1 is a cable core, 2 is a tape, 3 is a tape pad, 4 is a bottom plate 5 and a back plate 6.
7 is a base, and 8 is a tape guide.

The cable core 1 advances in the direction of arrow A in the figure, but since it is of a winding and rotating type, it advances while twisting and rotating in the direction of arrow B.

Therefore, the tape 2 fed out from the tape pad 3 is attached vertically at a predetermined winding angle according to the twist of the cable core 1. In this case, the tape feeding device 4 is rotatable in a plane parallel to the plane of the base 7, as shown by arrow C, and perpendicular to the cable traveling direction in a plane parallel to the plane of base 7, as indicated by arrow D. It is configured to be movable in the direction. Therefore, the optimal wrapping angle of the tape 2 around the cable core 1 can be easily obtained, and the tape 2 can be attached vertically while preventing wrinkles from forming at the ends.

FIG. 2 is an explanatory plan view of the tape feeding device 4 placed on the base 7. As shown in FIG.

The bottom plate 5 of the tape feeding device 4 is provided with arc-shaped elongated holes 9 at three locations, and the base 7 is provided with linear elongated holes at positions corresponding to the elongated holes 9 as shown by broken lines. 10 are provided. Therefore, the tape feeding device 4 is rotatable in a plane parallel to the base 7 surface, and linearly movable in a direction perpendicular to the traveling direction of the cable core 1.
After adjustment is made to obtain the optimum wrapping angle, bolts or the like can be inserted into the elongated holes 9 and 10 to fix the two.

As explained above, the tape longitudinal attachment device of the present invention is provided with a tape feeding device that is rotatable in a plane parallel to the base plane and movable in a direction perpendicular to the cable traveling direction in the plane. , vertically attached molding is possible even with the optimal wrapping angle of the tape around the cable core. Therefore, even with an extremely simple device, it is possible to vertically apply the tape while preventing wrinkles from forming at the edges.
