Abstract: A cutting wheel assembly for cutting elongated articles having a cylindrical housing which defines a longitudinal cavity and a circular outer periphery. A plurality of cutting blade support rings are rotatably mounted about the outer periphery of the housing. A plurality of cutting blades are mounted for radial movement on each ring and disposed at angularly spaced increments about the housing, wherein each blade is moveable between a first, non-cutting position and a second, cutting position. A manifold and valve assembly is mounted in the cavity and proximate the blades for selectively directing a pulse of fluid against individual blades at preselected angular positions to urge the blades outwardly from the non-cutting position to the cutting position. A plurality of camming components are positioned about the periphery of the housing and secured against rotation adjacent the rings.

Abstract: A cutting wheel assembly for cutting elongated articles includes a substantially cylindrical housing which defines a longitudinally disposed cavity and a substantially circular outer periphery. A plurality of cutting device support rings are rotatably mounted about the outer periphery of the cylindrical housing. A plurality of cutting devices are mounted for radial movement on each cutting device support ring, and disposed at angularly spaced increments about the cylindrical housing, and wherein each cutting device is radially moveable between a first retracted non-cutting position, and a second extended cutting position. A manifold and valve assembly is mounted in the longitudinally disposed cavity and proximate the cutting devices for selectively directing a pulse of fluid against individual cutting devices at a preselected angular position to urge the respective cutting devices substantially radially outwardly from the retracted non-cutting position to the extended cutting position.
