ABSTRACT:
A continuously moving web passes over a fixed female die, which die is slotted to define a U-shaped cutting edge. A cylindrical punch rotates on an axis above the path of the web so that a cutting edge defined at the free end of the punch moves into the slot defined in the fixed die to cut a tab in the web. The length of the tab so cut can be varied by changing the relative speed of movement between the punch and that of the web, and the punch is mounted at an offset to its rotational axis. If such offset is positive, that is in the direction of rotation, the tab can be formed to "lead" the web. Providing the offset in the opposite or negative direction, the tab "trails" the web.
