Sprimag's Flat Bed Coating Machines Flat bed spraying machines are used for spray-coating of flat parts. Unlimited drying and cooling times, as well as many different coating processes are able to be achieved. The parts are transported by means of a rope or chain conveyor. Paternoster transport systems have the advantage of using a single operator for loading and unloading parts to be coated. The control system regulates servo-drive spray sliding carriages together with variable spray width, spray time and stroke speed. Modifications and storage of the above data is user friendly and can be done at any time.
