摘要

A knife drum for a cross cutting machine comprises a drum having an axial groove and a knife inserted in the groove with one side abutting one side of the groove. The space formed between the knife and the other side of the groove defines a downwardly tapering groove wherein a plurality of round chocks are mounted and which are selectively positioned in the radial direction. The chocks have an arcuate cross section with the largest diameter greater than the smallest width of the tapered groove, whereby in response to the radial positioning thereof, the knife is alternatively clamped between the chocks and one side of the groove or released.
