摘要

The rotary shears crop rolled wire, mould at high speed, and has two counter rotating blade heads. The top head (4) is rigidly coupled to the shaft (7) inside a hollow shaft (11). The head shaft piston rod (8) of a double-acting hydraulic ram (9), protruding inside the hollow shaft. The parting mechanism, comprising the head, its shaft, and the piston rod, is movable in the axial direction. ADVANTAGE - Faster working rate and improved reliability.
