The chosen system utilized a heavy-duty "clam shell" grab supported
from an automated overhead crane, accumulating powered roller conveyors
and an "upender". In response to an operator signal, the slit rolls
were precisely grabbed from one of two positions at the slitter.
The crane was then programmed to lift the rolls and follow a set
route to an awaiting pallet on the powered roller conveyor. A rotating
shuttle conveyor was used to send rolls to one of two lines. One
line would first upend the rolls to change the orientation and the
other would leave them in their original orientation based on the
shipping instructions.
