During such positioning of the slotter knife, it is held stationary while the annular support head is rotated. This slotter knife is releasably mounted on its head and a means is provided to selectively release the lock when it is desired to reposition the knife. The knives on one slotter shaft cut a slot on the leading edge of a first blank and the trailing edge of a following blank. The knives on the other slotter shaft cut the slot on the trailing edge of the first blank and the leading edge of the following blank.
