ABSTRACT:
A sheeter head having a pair of counterrotating internally-driven sheeter rollers is disclosed. The sheeting rollers each include an independent internal drive motor and gear box affixed to a nonrotating shaft, along with a nonrotating idle shaft on an opposite end of the roller. The speeds of the drive motors are controlled by an external device such as an inverter speed control. The nonrotating shafts, in conjunction with the absence of any external drive mechanism, allow for sanitary operation, easy clean-up, and a simple and efficient adjustment mechanism for varying a pinch point between the rollers. The preferred adjustment mechanism includes a fixed front roller and horizontal slide plates connected to the axles of a back roller, the slide plate having pegs which slide in associated grooves. One of the grooves is preferably wider than the other to help prevent binding during an adjustment operation. The preferred sheeter head further includes a releasable connecting assembly so that the sheeter head may be decoupled from a discharger conveyor.
