ABSTRACT:
Herein disclosed is an apparatus for changing the rotary position of a slotter member and for changing the relative position between fixed and movable knives mounted on the slotter member. The apparatus comprises a first rotatable shaft having at least one of the slotter members secured thereto; the slotter member having a fixed knife secured thereto and a movable knife mounted thereon; a driving apparatus; a first phase changing mechanism connected between the first shaft and the driving apparatus for rotating the slotter member; a second rotatable shaft spaced from the first shaft; a linking mechanism connected between the second shaft and the movable knife on the slotter member; a second phase changing mechanism connected between the first shaft and the second shaft for rotating the movable knife through the linking apparatus; and a selectively operable remote control apparatus for operating the first phase changing mechanism to selectively change the rotary position of the slotter member forward and backward with respect to the driving apparatus, the second phase changing mechanism and the linking mechanism maintaining the relative position of the fixed and movable knives during operation of the first phase changing mechanism, and for operating the second phase changing mechanism independently of the driving apparatus to selectively change the position of the movable knife forward and backward relative to the position of the fixed knife.
