Abstract
The transport device for conveying products has several symmetrically configured, movable carriages having inverted U-shape, each carriage having permanent magnets, also has an endless guide rail for guiding the carriages and a linear-motor drive device to drive the carriages. Each symmetric half of each carriage has three running rollers projecting inwardly from sidepieces of the carriage. The three running rollers of the first half rest on first and second guide surfaces on a first side wall of the guide rail, and the three running rollers of the second half rest on first and second guide surfaces on the second side wall of the guide rail. Each guide surface is arranged at an acute angle to a longitudinal center plane of the transport device, and the two guide surfaces of each side wall are at an angle of 80° to 100° to each other.
