Abstract

In position the blade (131) is held against the flat surface of a semicircular packing sleeve (10) by a plunger (5) spring loaded to move away from the blade. The head of the plunger rests against the cam-shaped surface (14) of a clamping ring held in the blade loaded position by a torsion spring. Rotating the ring releases the plunger enabling the blade to be removed and replaced. To locate the blade the packing sleeve has slots formed between it and the reciprocating drive sleeve (11).
