Determination of the camber in a calender roll for polymer reworking

A procedure is proposed for determination of the deflection of calender rolls for polymer reworking with consideration of the mutual effect of thrust forces in the inter-roll gap, and the size of the gap, as well as the transverse stiffness of a roll. It is demonstrated that the deflection calculated on the basis of the proposed procedure is 25–30% smaller than deflection determined from the traditional computational procedure; it is expedient to consider this in determining the camber of a roll to compensate for its deflection during operation of the calender.
