ABSTRACT:
A roof unit for an automobile is composed of a roof panel and stiffeners welded thereto. One roof panel is unloaded from a stack of roof panels stored in a carriage, and fed to a working station. The stiffeners which are coated with a sealer are also fed to the working station. The roof panel and the stiffeners are then welded into a roof unit in the working station. An apparatus for manufacturing a roof unit includes a first feed mechanism for unloading a roof panel from a stack of roof panels and feeding the unloaded roof panel to the working station, a second feed mechanism for feeding sealed stiffeners to the working station, a third feed mechanism for feeding a jig to the working station to assemble the roof panel and the stiffener into a roof unit in the working station, and a fourth feed mechanism for feeding the roof unit from the working station. The first through fourth feed mechanisms are disposed around the working station and oriented in respective different four directions therearound.
