A conveyor of product units has mounting brackets extending laterally from endless chains. The mounting brackets rotatably mount two spools having axes parallel to the conveying path. The mounting brackets are displaced longitudinally one from another. Consequently, a central elongate cavity is defined along the conveying path between laterally adjacent spools. Further, lateral concavities are presented between rollers on individual spools and between rollers on separate spools. Pivotally mounted off-loading elements can be articulated to lift product units positioned on the conveying system for off-loading laterally from the conveyor. A laterally articulated actuator is located below the principal conveyor. The actuator includes laterally slidable slats which frictionally engage the overlying rollers associated with each mounting bracket. Guides are then arranged to move the slats laterally with motion of the conveyor. With lateral motion of the slats, the rollers are caused to rotate. Through control of the slats, product units may be rotated by one-half, one-third or even one-quarter of a revolution. Successive movements of the slats will provide further segments to be viewed. |
