Abstract

PURPOSE: To improve accuracy of cutting by preventing bending of arbors, due to reaction from the shearing force generated by the circular cutters, through the installation of a strength back-up device consisting of back-up rollers set against each arbor of upper and lower circular cutters.
CONSTITUTION: Upper circular cutters 2 and lower circular cutters 2' are mounted on the arbor 1 and the arbor 1', respectively, at positions designated depending on the slitting width of the metal band 3. Back-up rollers 4 and 4' are set against the outer circumference of upper arbor 1 and lower arbor 1', respectively, and prevent the bending of arbors due to reaction from the shearing force generated by the circular cutters during slitting of the metal band 3. Thus, slits of improved accuracy can be obtained.
