ABSTRACT:
A conveyor for the nonforced displacement of a multiplicity of workpiece-supporting carriages along a transport path whereby the carriages can be selectively stopped and, after unloading, are returned to the starting end of the conveyor. Flanking this path there are provided upwardly-open upper channels and laterally open lower channels, each upper and lower channel on a respective side of the path receiving a roller conveyor chain so that rollers of the conveyor are supported upon the bottoms of each channel. The chain has central rollers which support the carriage along the upper stretch of the chain while the lateral rollers engage the bottom of the upper channel. On the return stretch, the central rollers support the chain on the lower channel while at least one of the lateral rollers supports the returning carriage through brackets which reach around the channels and form guides for laterally positioning the carriage with respect to both upper and lower channels. The space between the chains is free from cross bars or the like.
