Abstract
A production line comprises production devices arranged in a line for machining a workpiece by conveyance of the workpiece successively to the production devices. Each of the production devices has a machine for machining the workpiece, an individual base for supporting the machine, a mounting unit that removably integrally mounts the machine on a surface of the individual base, and a positioning/moving unit that positions the machine on the surface of the individual base and that facilitates sliding movement of the machine along the surface of the individual base to permit the machine to be slidingly drawn of f of the surface of the individual base when the machine is not mounted on the surface of the individual base by the mounting unit. The line unit also comprises a maintenance stand onto which the machine slidingly drawn off of the surface of the individual base is placed for transportation away from the production line and/or for undergoing a maintenance operation.
