Abstract
PURPOSE: To decrease the amount of production of defectives and improve the yield of products by advancing a metal strip coil, process by process, between the presses provided with male dies and female dies of process sequence, at the time of tabbing said coil.
CONSTITUTION: A metal strip coil 20 is inserted between presses consisting of securing bases 1, 11 secured with plural male dies 2aW2f, female dies 12aW12f taking charge of partial working of tabbing. First, long holes 21, 21', circular recesses 22, 22', and small holes 23, 24, 23', 24' are formed by pressing. Next, the securing bases 1, 11 are opened, and the metal strip 20 is advanced by one process. Again the upper, lower securing bases 1, 11 are closed and the coil is tabbed successively by the male, female dies 2b, 12b,.... In this case, two adjoining tabs are formed by approaching the recess of one tab to one side in the lengthwise direction of the metal strip coil and approaching the recess of the other tab to the other side in the lengthwise direction of the coil.
