Roller assembly for feeding stacked sheet material

Roller assembly for feeding stacked sheet material

A roller assembly (12, 14) for conveying stacked sheet material along a feed path. The roller assembly (12, 14) includes a first roller (24) adapted for rotation within a housing, a second roller (26) pivotally mounting about an axis (34A) to the housing and opposing the first roller (24) to define...

description A roller assembly (12, 14) for conveying stacked sheet material along a feed path. The roller assembly (12, 14) includes a first roller (24) adapted for rotation within a housing, a second roller (26) pivotally mounting about an axis (34A) to the housing and opposing the first roller (24) to define a roller nip, a spring biasing mechanism (40) operative to bias the second roller (24) about the pivot axis (34A) toward the first roller (24) to effect optimum frictional engagement of the roller nip with the face surfaces of the stacked sheet material and a transmission assembly (50) operative to (i) transfer rotational motion of the first roller (24) to the second roller (26), (ii) drive the first (24) and second (26) rollers in opposing directions to convey the stacked sheet material along the feed path, and (iii) facilitate pivot motion of the second roller (26) about the pivot axis (34A) to vary the spacing of the roller nip and accommodate stacks of sheet material which vary in thickness.
