The apparatus comprises a plurality of driven transport wheels (2) each suspended for rotation about a centerline (3) thereof and for pivotal movement about a steering axis (4) directed perpendicularly to the transport surface (1), and a string (5) passing over a driving and a driven sheave (6 and 2, 7, respectively). The driven sheave (2, 7) is pivotable along with the associated transport wheel (2). According to the invention, the string (5), between the driving and the driven sheaves (6 and 2, 7, respectively), passes closely to the associated steering axis (4) over divert rollers (8).

A conveying apparatus for displacing articles having at least one substantially flat side along a transport surface in different directions, said apparatus comprising: a plurality of driven transport wheels each suspended for rotation about a centerline thereof and for pivotal movement about an associated steering axis directed perpendicularly to the transport surface; and at least one string passing over a driving sheave and driven sheaves and, between said driving sheave and each of the driven sheaves, at least two divert rollers from which the string extends to the same driven sheave, each of said driven sheaves and said at least two divert rollers each being associated with one of the transport wheels, the driven sheaves each being pivotable along with the associated transport wheel about the associated steering axis; wherein the string passes over each of the divert rollers in an area close to the steering axis of the transport wheel associated with said divert rollers.
