Abstract
A horizontal perforation forming apparatus for a rotary press includes an interaxial distance adjusting unit for adjusting a distance between axes of perforation and mating cylinders. The apparatus also includes a phase adjusting unit having a phase adjusting shaft which is axially moved to pivot the perforation cylinder. The phase adjusting shaft is moved upon pivotal movement of an operation shaft of the interaxial distance adjusting unit.
Claims10
A horizontal perforation forming apparatus for a rotary press comprising:
- a perforating cylinder having a perforation blade extending substantially parallel to a longitudinal axis of said perforation cylinder;
- a mating cylinder mounted adjacent said perforation cylinder, said mating cylinder having a perforation blade seat extending in an axial direction of said mating cylinder, said perforation blade and perforation blade seat being adapted to cooperate with and oppose each other upon rotation of said perforation and mating cylinders;
- drive gear means for driving said perforation cylinder, said mating cylinder being directly geared to said perforation cylinder so as to provide proper mating of said perforation blade with said perforation blade seat, said drive gear means having a gear shaft;
- interaxial distance adjusting means for adjusting a distance between axes of said perforation and mating cylinders;
- and
- eccentric shaft coupling means coupled with said gear shaft and said perforation cylinder, said eccentric shaft coupling means having a first support portion attached to said perforation cylinder, said eccentric shaft coupling means having a second support portion attached to said gear shaft, said second support portion being eccentrically coupled with said first support portion to produce an eccentric action therebetween, said eccentric shaft coupling means allowing said interaxial distance adjusting means to adjust said distance without producing an angular phase shift between said drive gear means and said perforation cylinder, said eccentric shaft coupling means allowing equal adjustment of said distance between axes of said perforation and mating cylinders while enabling said perforation blade and said perforation blade seat to remain substantially opposing.
