(back to Polyurethane Fabrication Page)Tension Rolls, Feed Rolls, Pinch RollsRoll Hardness - 80-90 Shore A, 50 Shore A and softerSurface 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 RollsRoll Hardness - 75-89 Shore ASurface 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 RollsRoll Hardness - 80A-40 Shore DSurface Finish - Standard Machime 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 sofer durometers. Able to dissipate build up in roll body in high speed applications. Accumulator Rolls, Application RollsRoll Hardness - 50-75 Shore ASurface 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, PulleysRoll Hardness - 80-90 Shore ASurface 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. |
