The Use of Skewed Rolls in Calendering Operations

In many commercial operations it is desirable to produce a uniform sheet of material by passing the viscous raw ingredients through rotating cylindrical rolls. With rolls supported at the ends only there is danger of wide variations in thickness of the finished product. This may be overcome by “skewing” the rolls the amount necessary for any given thickness and material properties. This paper presents an analytical approach to determining the optimum operating position of the rolls.
