Abstract
A roll stand for use in the extrusion forming of a sheet product from a flowable material having a main frame supporting first and second rolls between which there is a first gap through which at least one sheet layer passes during sheet product formation. A first adjusting mechanism moves the first roll relative to the second roll so as to vary a dimension of the first gap. The first adjusting mechanism has a first element that is moved by a first actuator that is: a) maintained on the apparatus; b) engageable by a hand of an operator; and c) manually movable through an operator's hand to thereby cause repositioning of the first roll.
