The performance of Rubber Expander Rollers depend upon:
Lead-in Lead-out distance
Position of Bow(adjustable)
3:1 lead-in : lead-out ration is considered to be best. However, lead out distance preferably should not be more than 3 times of expander roller diameter. Bow roller positioned perpendicular to the web direction gives best result.
