Abstract
Slitting apparatus for trimming the edges of a web of corrugated board and longitudinally cutting the web into a plurality of narrow webs is constructed with selectively operable fluid operated means that clamps the working heads in adjusted positions along the length of their respective drive shafts. The fluid operated means includes a plurality of spring steel pressure bars extending parallel to the length of each shaft and disposed within different grooves thereof, with each pressure bar being operatively positioned to clamp a plurality of heads in operating positions by engaging keys secured to these heads. The keys extend beyond the faces of the heads and for each of the heads include notches that provide clearance for the extending portions of the keys secured to adjacent heads. The drive shafts are parallel to each other, and one of these shafts is longitudinally movable after the heads are locked in place so that the knives mounted thereon positively mate with or engage cooperating knives on the other shaft.
