KNIFE ASSEMBLY FOR CORRUGATED KNIFE BLADE AND CUTTING SYSTEM EQUIPPED WITH SAME

摘要

A knife assembly comprising: a corrugated knife blade, a holder, a clamp arranged for clamping the knife blade onto the holder, and a fastening mechanism for securing the knife blade between the clamp and the holder. The clamp has clamping parts along a clamping line rearward from the front edge. The clamp comprises clamping geometrical elements, corresponding to complementary contact geometrical elements of the knife blade, positioned at least in part at a different distance from said front edge than the clamping line. The clamp engages the knife blade along the clamping line and at the corresponding contact geometrical elements.

1. A knife assembly comprising:
a knife blade of which a front edge is a cutting edge, the knife blade being a corrugated knife blade comprising a corrugated part having a continuous shape defining a periodic pattern of peaks and valleys over a certain distance; a holder configured for supporting the knife blade; a clamp arranged for clamping the knife blade onto the holder; and a fastening mechanism cooperating with the holder and clamp for securing and clamping the knife blade between the clamp and the holder with the cutting edge protruding at the front side, the clamp having clamping parts along a clamping line for engaging the knife blade at a complementary contact line on the knife blade rearward from the front edge of the knife blade; characterized in that the clamp has an inwardly corrugated shape complementary to that of the knife blade and comprises one or more clamping geometrical elements corresponding to complementary contact geometrical elements of the knife blade, the clamping geometrical elements being positioned at least in part at a different distance from said front edge than said clamping line and being arranged such that in clamped state the clamp engages the knife blade at least partly along the clamping line and at the corresponding contact geometrical elements.
