A bundle builder and lifter assembly has a pair of parallel cross beams, and an actuator assembly for actuating the builder and lifter assembly. A pair of lift arms are moved along the parallel cross beams and each has a vertical portion and a horizontal portion forming a finger. The lift arms are also raised and lowered. A conveyor roller assembly is positioned above the lift arms and cross beams, where stacks of material are moved on the rollers of the conveyor assembly. The stacks of material are placed in a stack by the lift arms forming a bundle, which is then removed from the conveyor roller assembly.
