1. Apparatus for manufacturing major subassemblies of electric motors, comprising:

  • two production lines disposed side by side and separated along at least part of the length thereof by a common partition;

    either production line being capable of performing at least one operation on subassemblies being produced on the other production line;

    means for transferring at least some of the subassemblies from one to the other side of said partition for enabling said one operaton to be performed on the transferred subassemblies;

    each said production line including a coil winding station, said at least one operation comprising coil winding, and said transferring means being disposed upstream of said coil winding station;

    return transfer means, disposed downstream of said coil winding station, for transferring said transferred subassemblies back to their original production line on said one side of said partition;

    buffer storage means for storing parts of the electric motors, said buffer storage means comprising a horizontal platform for supporting said parts in layers, and means for lowering said platform as the latter is loaded and for maintaining said platform horizontal as it is lowered;

    each end of said platform being supported by a respective belt which is connected at one end to the platform, passes upwardly and over a respective wheel, and is connected at the other end to a spring;

    each said wheel being provided with teeth which mesh with teeth of the respective belt; and

    the respective wheels being spaced apart and interconnected by a chain arranged in a figure eight configuration, whereby any vertical movement of one end of said platform is accompanied by an equal vertical movement at the other end of said platform.
