An apparatus for forming a sheet of material from a supply of the material includes a pair of rotatable rolls that define a gap which forms the material into a sheet. The size of the roll gap is maintained constant during the sheeting operation despite forces exerted on the apparatus caused by inconsistencies in the material being sheeted. The apparatus has a force-applying mechanism which applies a selected amount of force against one of the rolls to bias the one roll toward the other roll, the amount of force being sufficient to overcome any force exerted on the apparatus by the material during sheeting, which forces would otherwise result in variations in the size of the roll gap and the thickness of the resulting product. The one roll is movably mounted in scissor-like fashion and is acted on by the force-applying mechanism in a direction which biases the one roll against the other roll.
