Abstract
In a printed web strip cutting machine, the cutting cylinder is divided diagonally by a formed septum into two isolated chambers. The cylinder is mounted on hollow shafts connected to an exhaust system. Each hollow shaft communicates with only one of the two chambers to draw a current of air into the chamber between the spaced cutting knives. The web support beneath the cylinder has vents to provide air jets to lift the severed strip into the air current between the knives.
