ABSTRACT:
Conveyor apparatus includes at least two conveyors, each comprising a pair of longitudinal conveyor members, situated in different horizontal planes on which workpiece carriers are supported for conveyance. Each workpiece carrier has at least one longer outer dimension, e.g. length, greater than the distance between the conveyor members of one of the conveyors and at least one shorter outer dimesnion, e.g. width, less than the distance between the conveyor members of at least one of the conveyors. The apparatus further includes an arrangement for transferring the workpiece carriers between the conveyors including a device for rotating or pivoting a workpiece carrier to an angular position wherein the shorter outer dimension is aligned transversely with respect to the conveyor members of the conveyor on which it is supported so that the workpiece carrier can fit between them, and a lift device for moving the workpiece carrier from the conveyor on which it is supported to the other conveyor with the workpice carrier moving between the conveyor members of the former.
