ABSTRACT:
Apparatus for severing sections from a web of material advanced by a feed roller comprises helical cutting blades on cylinders interconnected by helical gears. The feed roller can be coupled to and uncoupled from a drive by a dog clutch and the cutting cylinders are positively connected to the drive. Means are provided for axially displacing one of the cutting cylinders when the feed roller is being uncoupled from the drive, whereby to separate the cutting blades, and for returning the cylinder to bring the blades back into cutting relationship when the feed roller is being coupled to the drive.
