## Abstract

The present specification describes and claims a method and apparatus for cutting elongate material into predetermined lengths. The apparatus comprises a cutting assembly including a cutter wheel having a number of spaced apart knife edges projecting radially outwardly in the region of its periphery. Winding means are provided for winding successive layers of material to be cut in contact with the knife and a pressure wheel forces the material onto the knife edges as the cutter wheel rotates. Press nip rollers are arranged to feed the material to the cutter wheel and both the cutter wheel and the press nip rollers are driven by the same motor.

## Claims

### Claim 1

An apparatus for cutting elongate material into predetermined lengths comprising a cutting assembly including a number of spaced apart knife edges secured to a mounting member, winding means for winding successive layers of material to be cut in contact with the knife edges, means for forcing the material onto the knife edges to thereby sever the material, press nip rollers arranged to feed the material to the cutting assembly, common motor means having an operative connection with both the winding means and the press nip rollers, and variable transmission means in said operative connection for varying the relative speeds of the winding means and the press nip rollers,

### Claim 2 (depends on 1)

An apparatus according to claim 1, wherein the variable transmission is provided between the common motor means and the press nip rollers.

### Claim 3 (depends on 1)

An apparatus according to claim 1, wherein the common motor means is an electric motor.

### Claim 4 (depends on 1)

An apparatus according to claim 1, wherein the cutting assembly includes a cutter wheel having a number of spaced apart knives located in the region of its periphery, the knife edges projecting radially outwardly of the wheel which is rotatable by means of said common motor means.

### Claim 5 (depends on 4)

An apparatus according to claim 4, wherein a pressure roller is arranged to engage material wound onto the cutter wheel and forms said means for pressing the material against said knife edges.
