Claims20
An apparatus for cutting and dividing a continuous stream of printed product, said apparatus comprising:
- a first rotatable cylinder and a second rotatable cylinder, each having means for cutting said continuous stream of printed product into a given length, and each cylinder being disposed to draw said continuous stream of printed product therebetween in use, both said cylinders having at least one cutting blade and at least one rubber strip disposed in each of said cylinders;
- means for aligning each cutting blade of each of said cylinders with a corresponding rubber strip of the other of said cylinders during rotation of said cylinders for cutting said printed product;
- diverter means disposed in each said cylinder for directing leading edges of printed product being cut;
- said diverter means in said first cylinder being disposed to direct leading edges of a first cut portion of said printed product in a first printed product path;
- and
- said diverter means in said second cylinder being disposed to direct leading edges of a second cut portion of said printed product in a second printed product path.

An apparatus for cutting and dividing a continuous stream of printed product, said apparatus comprising:
- a first rotatable cylinder and a second rotatable cylinder, each having means for cutting said continuous stream of printed product into a given length and each cylinder being disposed with respect to the other to move said continuous stream of printed product therebetween in use;
- diverter means disposed in each said cylinder for directing leading edges of printed product being cut by said cutting means;
- means for driving said diverter means in each cylinder opposite the direction of rotatability in use of the cylinder in which each said diverter means is disposed;
- said diverter means in said first cylinder being disposed to direct leading edges of a first cut portion of said printed product into a first printed product path;
- and
- said diverter means in said second cylinder being disposed to direct leading edges of a second cut portion of said printed product into a second printed product path.
