Abstract: The invention relates to a flexible production line for machining undulated workpieces arranged individually or in groups on a pallet, in a plurality of successive operations (OP-20, OP-40) carried out along from pallet stores. In order to machine series' of workpieces, the entire production line is divided into a plurality of decoupling modules. A plurality of operations (OP-20, OP-40) are associated with each decoupling module. A stacker for individual pallets is associated with each decoupling module. Each decoupling module has at least one store for pallets and the decoupling modules are interconnected by transfer conveyors.
