Description

[Detailed Description of the Invention] Conventionally, connecting the terminal end of a coil winding plate and the starting end of a coil unwinding plate in a slitter line, etc. required a lot of effort, time, and skill, which significantly impeded work efficiency. This is what I used to do. Therefore, a technique has been developed in which adhesive tape is pasted on the upper surface of the abutment connection between the end and start ends, but the adhesive tape is cut in advance to the abutment width and wound onto a supply reel, and then rewound to form the abutment connection. Since it is attached only to one side, sufficient connection strength cannot be obtained, commercially available roll-up adhesive tape cannot be used, and it is attached only during the forward movement of the reciprocating motion, but not during the backward movement. There were some problems, such as not being able to do so.

The present invention aims to solve the above problems.

In the present invention, a pair of plate clamping devices are provided in the machine frame, and a tape pasting device for connecting the abutting ends of the plates is disposed between the two devices so as to be movable horizontally in the direction of the abutting ends. The application device can rotate 180 degrees around a common vertical centerline, and is composed of an adhesive tape application machine for connecting the upper and lower surfaces and a tape end cutter, and tape start end cutters are provided at both ends of the reciprocating movement of the application device.
