One common approach is to pre-grind a camber into the top roll to

Transferring the rubber sheet from the calender roll to
Easy read Pi tape: This tape will accurately measure the diameter of a roll to
As of May 22, he said, the Tax Commission computers were showing accepted offers of $600 million dollars off the actuals, which would have brought the final roll to
It moves on tracks to four positions, picking up film rolls from face-to-face winders, taking the roll off the shaft and transporting the roll to
a dolly or roll stand, then tilting to unload the roll.
Dimensional accuracy - using the roll to
pull compound from the preform bank past the final shaping die results in zero pressure extrusion and a dimensionally accurate product.
A new patented, copper chill roll for cast film reportedly cools so much more efficiently than conventional steel rolls that it provides dramatically higher output for the same roll diameter or allows a smaller roll to
be used for the same output.
By correctly adjusting the roll temperature and the circumferential speed of the roll to
match the extruder output and the take-off speed, even complex profiles with large thickness variations and long angled tips can be made without problems.
If enough air isn't wound into the roll to
allow for that shrinkage, the roll hardens and can crush the core.
Variable friction allows for controlling the rate of work input into the stock in the calender nip and influencing the transfer of stock from one roll to
Liquid-heated rollers consist of either a simple single shell or more commonly of a spiral-baffled, double-walled roll to
maintain more consistent thermal transfer across and around the roller.
In some cases a mechanical interlock to the roll is an adequate bond for performance, but an adhesive can be applied to the roll to
achieve a higher level of bonding between the elastomeric alloy and the roll surface.
