DEFINITION

Classification: 401/64

(under subclass 63) Implement in which the advancing means includes a member with a helical camming surface and in which the carrier# and the plunger are each provided with a cam follower element individually directly engageable with the camming surface so that each is axially displaceable relative to the member upon relative rotation between the member and each of such plunger and carrier elements and the plunger is axially displaceable relative to the carrier.

(1) Note. Ejection of the piece of material occurs when the axial movement of the carrier ceases as a result of its disengagement from the camming surface while the plunger continues to be cammingly advanced through the carrier.
