ABSTRACT:
A blade mounting arrangement for mounting a cutoff blade in a roll of a shear cut type, cut-off system includes an elastomeric member interposed between the cutoff blade and a mounting surface of the roll. The elastomeric member is configured and arranged to provide varying resistance to compressive loading, the resistance varying along a portion of elastomeric member. In one embodiment, the elastomeric member includes a first resistance portion which engages the cutoff blade near a fixed inner edge portion of the blade, and a second resistance portion which underlies the cutoff blade near its free edge portion. The second resistance portion is thinner than the first resistance portion providing a gap between the free edge portion of the cutoff blade and the second portion, the free edge portion of the cutoff blade engaging the second resistance portion only when the cutoff blade is subjected to a load force that is greater than a predetermined value. The elastomeric member includes a third portion disposed intermediate the first and second portions and joining the first portion to the second portion but configured so as to be maintained out of engagement with the cutoff blade both for non-loaded loaded conditions for the free edge portion of the cutoff blade.
