A position determination device (7, 8a, 8b, 8c) enables the momentaneous position of each workpiece (1a, 1b, 1c) to be determined. A control system (5) is used to apply a control signal to the corresponding voltage regulating unit (4a, 4b, 4c) in such a way as to maintain each workpiece (1a, 1b, 1c) at a desired voltage in each position of the course thereof through the bath of enamel.
The invention relates to a transport system (10) for simultaneously transporting workpieces (28) and assemblers on a production line (12) comprising at least one rectilinear production section (18, 20) for several guided motor vehicles (22), each of which is provided with a mounting platform (24) which extends along the entire vehicle length and on which the assemblers can move, wherein said vehicles can form a train (30) during the displacement thereof along the production line (12). Each mounting platform is provided with its own drive (42). Said drives are controllable in such a way that the vehicles are driven in the form of a train (30) during the displacement thereof along the production section (18, 20). A method for simultaneously transporting workpieces (28) and assemblers along the production line (12) provided with at least one rectilinear production section (18, 20). The inventive method consists in driving the vehicles (22) in the form of a train by means of the drives (42) mounted on the vehicles (22) during the displacement thereof along the production section (18, 20).
