Abstract

A method of cutting a fed sheet-material into a cut segment and a remaining portion by engaging a movable cutting edge with a fixed cutting edge is disclosed, wherein the remaining portion after being cut off is fed in a spacing with a predetermined amount of insertion between the fixed and movable cutting edges. The top of remaining portion can therefore be prevented from being curled down forward in the moving direction of the movable and fixed cutting edges. An apparatus for cutting a fed sheet-material into a cut segment and a remaining portion by engaging a movable cutting edge with a fixed cutting edge is also disclosed, wherein a plate member incorporated therein hinders the movement of the top of remaining portion after being cut off together with the movable cutting edge. Hence, the top of remaining portion can be prevented from being turned up by the movable cutting edge.
