Abstract
Apparatus is described for adjusting backlash clearances between the flutes of two meshing corrugating rolls, while the rolls are rotating, permitting minimization of noise levels. The corrugating rolls are driven through a pair of meshing helical gears, one of which is free to move axially on its drive shaft. A mechanism moves the helical gear axially, resulting in a slight rotation of the corrugating roll drive shaft, relative to the other corrugating roll. The preferred mechanism is mounted about the drive shaft of the movable helical gear. A hand wheel adjuster is threaded onto a sleeve fixed to a frame or other support and contacts the rotating helical gear through a bearing mounted on a second sleeve fixed to the gear. Rotation of the hand wheel adjuster causes the adjusting axial movement of the helical gear system.
