Conveyor unit and air supply unit adjustment
1. Adjusting the conveyor unit
Each mechanism of the conveyor unit is arranged along the conveyor rails
and operates by air pressure or a servo motor. These conveyor units are
preadjusted at the factory prior to shipping. If for some reasons adjustment
becomes necessary, refer to the description in this section.
