Tension Rolls, Feed Rolls, Pinch Rolls
Roll Hardness - 80-90 Shore A, 50 Shore A and softer
Surface Finish - Diced Knife Slits; Sure Grip; Longitudinal Grooves; Smooth
Wear Requirements - More Abrasion than cut resistant. Must be able to provide high coefficient of friction under wet or dry operating conditions. Able to keep product conveyed in proper alignment.
Wringer Rolls
Roll Hardness - 75-89 Shore A
Surface Finish - 36-64 RMS finish; turned or precision ground
Wear Requirements - Urethane must be compatible with solution being processed. Cut resistant with an ability to wear uniformly across roll face. Able to process varied product widths without developing a pronounced wear pattern.
Break Rolls, Shearing Rolls, Bridle Rolls
Roll Hardness - 80A-40 Shore D
Surface Finish - Standard Machine Finish; Diamond Pattern or Herringbone Pattern
Wear Requirements - Must be able to accept minor compression under load without rupture during tracking. Harder durometers able to withstand more psi than softer durometers. Able to dissipate build up in roll body in high speed applications.
Accumulator Rolls, Application Rolls
Roll Hardness - 50-75 Shore A
Surface Finish - Ground 32 RMS finish
Wear Requirements - Minimum deflection of urethane to insure uniform coating of moving substrate. Good abrasion and cut resistant qualities. Able to minimize a wear pattern on roll face even when product width varies.
Conveyor Drive Rolls, Idler Rolls, Pulleys
Roll Hardness - 80-90 Shore A
Surface Finish - Standard Machine Finish; Diamond Pattern or Herringbone Pattern
Wear Requirements - Good abrasion qualities. Able to prevent impingement of metal particles in urethane coating. Uniform wear over roll face to insure proper tracking and alignment.
