Abstract

PURPOSE: To enable production of blanks from a coil in an blanking operation using 2 sets of press by inputting ≥2 kinds of signal for feed length to a feeding device of coil which gives a necessary feeding to each press.
CONSTITUTION: A coil material 5 is intermittently fed from an uncoiler 1 through a coil feeding device 2 to at least two presses A, B. In this case, a twin power press 3 has the first press A and second press B, wherein the press A performs notching process on the material 5, and the press B cutting process on it. Denoting (a) mm to a pitch between notches 6 on the material 5 and Lmm to a distance between a working place Q1 of the press A and Q2 of the press B, L-a×n=b is obtained, where (b) denotes a distance in mm between the working place Q2 of the press B and a center of the notch 6. The presses A and B have 180° phase difference, so that a blank 9 is produced by feedings of (a) mm and (b) mm alternately performed by the feeding device 2.
