Abstract: Pipes are moved transversely from one roller track to another one through two, bidirectional devices which in one example have a stationary and an up and down reciprocating member with shoes constructed to provide alternatingly downwardly inclined surfaces. Up and down movement results from pneumatic operation of an inflatable tube. The opposite direction of movement is provided for by a second up and down moving member with oppositely oriented roll-off surfaces.
