Abstract:
An adjustable cutting bar for use on a rotary press folding machine, comprising:a one-piece rotatable shaft supported on a frame;a first cutting blade secured to a first carrier bar assembly, the first carrier bar assembly being mounted to the shaft by a first pair of end brackets encircling the shaft, the first pair of end brackets being keyed to the shaft for common rotation therewith;a second cutting blade secured to a second carrier bar assembly, the second carrier bar assembly being rotatably mounted to the shaft by a second pair of end brackets encircling the shaft, the second pair of end brackets rotatable about a circumference of the shaft to thereby permit rotational adjustment of the second carrier bar assembly about an axis of the shaft in a circumferential direction, thereby permitting the circumferential position of the second cutting blade relative to the first cutting blade to be adjusted; anda drive system operatively connected to the first and second carrier bar assemblies for rotating the first and second carrier bar assemblies and their attached cutting blades at a common peripheral speed, the drive system including an axially moveable drive shaft, the circumferential position of the first carrier bar assembly and its attached cutting blade being adjusted relative to the second carrier bar assembly and its attached cutting blade in response to axial movement of the drive shaft.
