ABSTRACT:
A pack former includes a staging land for initially receiving a plurality of rolls in a row. A platen adjoins the staging land, and is sized in width to engage the row in an integer multiple of the rolls to set a pack width. An actuator reciprocates the platen over the staging land to push the row onto a conveyor belt. Disposed atop the conveyor belt are front and back guides spaced laterally apart to correspond with the pack width. A stop gate is disposed atop the conveyor belt to define a packing zone for collecting a plurality of rolls being transported by the conveyor belt, with the packing zone being sized in length to set a pack depth in integer multiples of the rolls. An actuator reciprocates the gate between open and closed positions to marshal the rolls in the packing zone in a specific width and depth configuration for subsequent transport atop the conveyor belt.
