Abstract
A dual nip release mechanism includes: a rigid actuator body including a tail portion with a handle and a pivotally-mounted head portion having a nose member extending therefrom; a rocker arm pivotally mounted about a rocker arm shaft, the rocker arm having a proximal end for engagement with part of the nose member and a distal end engaged with a first shaft; and legs hingedly connected to the tail portion, each leg having a foot engaged with a second shaft and a heel for camming engagement with a fixed plate. During use, actuation of the handle causes simultaneous movement of the first and second shafts from a nip closed position to a nip open position via pivoting of the rocker arm and simultaneous camming engagement of the heel with the fixed plate.
