Patent ID: 7634958

Claim:
A cutter for cutting elongate material into sections as the elongate material is fed past a cutting plane, said cutter comprising: a shaft rotatably supported by bearings and coupled to a shaft motor; an arm supported on said shaft and extending radially outward relative to said shaft, said arm being fixed to said shaft and rotatable therewith, said shaft motor rotating said shaft and thereby rotating said arm; a blade mounted on said arm and rotatable independently of said arm; a blade motor coupled to said blade and adapted to rotate said blade, wherein said shaft motor rotates said arm repetitively through 360 degrees such that said blade mounted on said arm passes through the elongate material to cut a length of material therefrom, said blade cutting a length of material from the elongate material once during each rotation of 360 degrees; and a controller controlling the shaft motor and thereby controlling the speed of rotation of the arm through the 360 degrees of repetitive rotation.
