Pressure roll assembly

Check all of the pressure rollers for wear and be certain there is no axial play in the rolls, especially the split rolls located adjacent to the blade. Then examine the roll yoke hinge pins and the bore in the pressure roll housing. If the hinge pin or bore is worn, the pressure roll housing must be dismantled, the holes bored over size and then bushed to match new pins. If the machine is a model 33, 55 or 75, the cast rolls rotate on hollow, ground, perforated shafts that wick oil for lubrication. Due to their age, these older pressure roll assemblies are generally worn to the point where extensive repair is required to make a “glue line cut”. All other models of machines use sealed ball bearings in their feed rolls.
