Abstract:
A block of a solid lubricant material, such as PTFE, is biased continuously or intermittently against the cutting edge of a rotary slitting blade for corrugated paperboard. The solid lubricant block prevents the build up of starch adhesive and biasing movement compensates for wear of the block and wear of the cutting blade edge.
