Abstract

The roll interference adjustment mechanism shown provides a very simple means of precisely adjusting the amount of interference of two driven rolls, such as the separator and restraint rolls of a roller paper separator. The idler mechanism provides the means for powering the roll while also allowing it to overrun or idle.

Roll Interference Adjustment Mechanism and Restraint Roll Idler Mechanism

The roll interference adjustment mechanism shown provides a very simple means of precisely adjusting the amount of interference of two driven rolls, such as the separator and restraint rolls of a roller paper separator. The idler mechanism provides the means for powering the roll while also allowing it to overrun or idle.

The compensator 1 fits over the restraint shaft 2. The worm 3 locates into two projections 4 at the base of the main housing. The worm 3 mates with a helical gear section projecting from the compensator 1. As the worm 3 is rotated it rotates the compensator 1 about the restraint shaft 2. Since the axis of the hole in the compensator 1 is eccentric to the main axis of the compensator, this rotation of the compensator raises and lowers its main axis.

The axis of the restraint roll 5, which rotates in the O.D. of the compensator 1, is coincident with the main axis of the compensator. Therefore, it also is raised or lowered allowing an easy, precise adjustment of the roll-to-roll interference between the separator and restraint roll 5.

A wave washer is sandwiched between the face of the worm 3 and one of the housing projections 4. This provides the locking effect necessary to prevent the worm 3 from rotating between adjustments, but is easily overcome when adjusting so as not to require loosening or tightening of a special lock before and after adjustment.
