ABSTRACT:
A method of restacking pulp slabs from a slab press allows smaller stacks to be conveyed on to a bale press without reducing the production rate of the slab press. A first stack having a predetermined number of slabs is conveyed to a transfer station, a top slab from the first stack is clamped and raised and the first stack with the remaining slabs is conveyed on for further pressing and packaging, a second stack of slabs is conveyed to the transfer station, the top slab from the first stack is lowered onto the second stack and then the top slab from the first stack and the top slab from the second stack are raised together, the second stack with the remaining slabs are conveyed on for further pressing and packaging, and then the top slab from the first stack and the top slab from the second stack are lowered to form a third stack which is conveyed on for further pressing and packaging.
