Abstract: A method for assembling body parts wherein at least two originally separate elements are brought to an assembly station, where they are held stationary with respect to one another and with reference to the assembly station. Supports, uniquely adapted to handle a plurality of models of parts grip the elements and are used to bring the elements to the assembly station and are thereafter transported to further assembly stations for the addition of additional elements as appropriate. The elements are joined together, for example, by welding.

Abstract: Pallet conveyor intersection apparatus having a central portion and plural conveyor portions connected to the central portion. Each of the conveyor portions has a pallet way along which pallets can be driven. The pallet ways of at least two of the conveyor portions are disposed at different levels, and the central portion is configured so that it can vertically displace a pallet, situated on the central portion, between levels corresponding to the different levels of the pallet ways of the conveyor portions. A pallet to be used in this system has a peripheral coupling which may be oriented facing at least one of the conveyor portions. The pallet's coupling can be engaged with or disengaged from a complementary coupling associated with the facing conveyor portion by vertically displacing the pallet.
