Abstract
Concerns mailing systems that automatically assemble mailings consisting of several brochures. The main component of the mailing (e.g. a book or a magazine) enters the conveyor belt (lug chain) at the loader module. Several supplements are added to the main product by a feeder module consisting of sheet-feeders. Sheet-feeders basically grab a brochure from a stack and put it on the conveyor belt (the master in this case). The main product, together with the supplements, form a package that is wrapped in plastic foil by a packaging module. The foil is supplied by a reel stand. Incorrect packages are removed at the rejection module. Finally, the product is released after which an address is printed on it, using a label or directly, via an inkjet printer. After this the product is put on a stack. The paper describes the control of the system, which involves synchronization between one master (the conveyor belt) and many slaves.
