LinerGuard is described as a unique design feature for cutting dies that reduces, and in most cases eliminates, cracking along scores on corrugated board, even with dry and recycled liner.
According to Jim Smithwick, VP of Engineering and Manufacturing, and the inventor of LinerGuard, “The system addresses the liner cracking problems associated with the conventional method of rubbering along creasing rule. With LinerGuard special elastomer is installed with a gap between itself and the creasing rule. A retaining system is installed along the elastomer on the opposite side. This prevents the elastomer, when compressed, from displacing in a direction away from the crease. LinerGuard directs the energy of the compressed elastomer towards the crease, thereby reducing tearing of the liner. It can be used with score, perf, and bundle breaker rule.”
