Abstract
PURPOSE:To eliminate the correcting work of a laminated core due to the deviation in the thicknesses of an iron strip plate at both ends at the laminating time by comparing the thicknesses of the plate at both ends with the predetermined thickness and controlling two pairs of uneven rollers displaced at their pitches to form uneven grooves on th strip plate. CONSTITUTION:An iron strip plate 1 is drawn from a roll 2, the thicknesses of both ends of the plate 1 are measured via thickness measuring units 4, and are compared with the predetermined thickness. Two pairs of uneven surface forming units 5 provided in the next stage are controlled in accordance with the deviation. The forming units 5 have two upper and lower forming rollers 5a, 5c and 5f, 5d dispsed to interpose the plate 1 therebetween in such a manner that the uneven groove pitches of the rewpective roller pairs are displaced by 1/2. The two pairs of the rollers are alternately engaged with the plate 1 in response to th deviation in the thicknesses of the plate at every predetermined pitches P1 to form uneven grooves on the plate to correct the thickness of the plate, while the plate is punched in a core shape by a punching mold 8, and the plates thus punched are laminated.
