Abstract:
1. A conveyor comprising a stationary track part, at least one stationary electric stator part that may be activated selectively to produce a travelling magnetic field and is arranged along the stationary track part, a sorter movably arranged to be driven along the stationary track part by means of drive means, and a plurality of article-supporting units arranged on the sorter, each unit having a flexible member defining an article-supporting surface and being arranged movably in a direction substantially perpendicularly to the direction of motion of the sorter, and a rotor susceptible to said travelling magnetic field and arranged to apply a driving force to the flexible member when co-operating with the at least one stationary electric stator part, wherein each article-supporting unit comprises a drive roller which over a part of its circumference is in driving contact with the flexible member, and a transmission means for transmitting driving force from the rotor to the drive roller.
