About arc high accuracy

Features of OS expander roll

OS expander roll is an expander roll that was developed about 60 years ago for use in our dyeing and organizing machines. Compared to other expander rolls, the surface of the roll is run-out polished after assembly, so it achieves a rotation accuracy of 0.02 or less, which is comparable to the run-out accuracy of straight rubber rolls.

If the arc height tolerance is large, the wrinkle removal effect may not be achieved.
