ABSTRACT:
A cutter drum for a web-cutting machine has a body having a cylindrical outer surface centered on an axis and formed with at least one seat having a radially outwardly directed floor face extending axially and helically of the axis and a tangentially directed rear face extending generally radially of the axis. A helically nonstraight blade lies flat on the floor face and has a front cutting edge lying radially outside the surface and a rear side confronting and spaced from the rear face of the seat. Blade bolts extending generally radially of the axis through the blade are seated in the body and secure the blade to the floor face with a possibility, when the blade bolts are not tightened, of limited movement of the blade on the floor face. A plurality of axially spaced spacer blocks each have a rear edge bearing against the rear face of the seat and a front edge bearing against the rear side of the blade. Respective block bolts extend through the blocks into the body and secure the blocks in the seat to the body.
