Abstract
In one embodiment, a system, comprising: one or more pairs of oppositely rotatable, laterally extending rolls, wherein for each pair, at least one of the rolls is moveable relative to the other of the rolls; a hydraulic circuit, comprising: a tensioner circuit comprising: for each pair of rolls, one or more pairs of hydraulic cylinders arranged in parallel, each configured to resist movement of the at least one of the rolls at a respective end of the at least one of the rolls; an accumulator arranged in parallel to the hydraulic cylinders; and plural control valves; and a computing system configured to cause the one or more pairs of hydraulic cylinders to adjust the resistance to movement of the at least one of the rolls of the respective pair of rolls by sending signals to one or more of the plural control valves.
