All the operations are executed by the operator seated in front of the machine. The operator passes the cover material into the gluing unit where it receives an even coating of hot gelatin glue.

Utilizing foot switches, the operator controls the air suction plate for perfect registering of the cover material. By the use of suction bars, the Active Dual Plus model automatically places the board pieces accurately on to the cover material.

Turning in of the cover material on all four edges takes place in only two passes of the case by the operator. This process is enhanced by the use of brushes and pressing rollers: an added benefit is that the Active Dual Plus model can also handle cases with a central window cut-out for photo album production. At this point the working process is completed and the final product is delivered to the rear of the machine on an inclined delivery table.
