Abstract

PURPOSE:To improve joining strength, and to simplify the device and apparatus, by overlaying one coil strip upon another coil strip, by forming a punched hole in this overlapping part, and by extruding one coil strip in the overlapping part on one side of this punched hole. CONSTITUTION:A coil strip 2a is uncoiled by the feed roll; when its tail end passes over above the first sensor 35, it is detected by the sensor 35 which stops the coil strip 2a so as to lay its tail end above the feed-in end of the jointer 14. Next, another coil strip 2b is uncoiled by the feed roll; when the top end of the coil strip 2b passes over above the second sensor 36, it is detected by the sensor 36 which stops the coil strip 2b at a position that its top end is overlapping upon the tail end of the coil strip 2a. Then, the cylinder 21 of the jointer 14 is operated to protrude the piston rod 22 in order to form punched holes 17, 18 in the overlapping part of the coil strips 2a, 2b and at the same time, in order to extrude the overlapping part 39 on one side of the punched holes 17, 18. Hereby, mutually overlapping tongues 40, 41 are formed, and the coil strips 2a, 2b are firmly jointed.
