Abstract
A roller nip assembly has a drive axle (with driver rollers) and a drive unit connected to a first end of the drive axle. The drive unit rotates the drive axle. In addition, a slotted mount is connected to a second end of the drive axle (opposite the first end). Additionally, an idler frame (with idler rollers) is positioned adjacent the drive axle. Further, a bias member is connected to the drive axle. The bias member moves the drive axle in the slotted mount to bias the drive rollers toward the idler rollers. The idler frame also includes a pivot structure. The bias member causes the drive axle to pivot. The pivot structure pivots the idler frame to compensate for the pivoting motion of the drive axle and to maintain pressure between the idler rollers and the drive rollers as the drive axle pivots.
