Abstract
A rotary cutter separates a molten plastic pellet from a nozzle and deposits the molten plastic pellet into a mold of a mold cavity. The cutter blade includes a cutter blade and a cutter shaft rotatable about an axis of the shaft. The cutter blade is mounted to extend radially from an end of the shaft, the shaft positionable adjacent the nozzle such that the rotary path of the cutter blade closely conforms to a facing surface of the nozzle. An air conduit extends through the cutter shaft to the cutter blade. An air orifice in communication with the air conduit is oriented to direct a stream of air radially along the cutter blade to displace a molten plastic pellet from the cutter blade with a stream of pressurized air. The delivery of pressurized air is precisely timed to displace the pellet from the cutter blade and into the mold cavity.
