1. A device for conveying thermoplastic material preforms for use in a heat treatment oven, said preform comprising a central elongate axis, said device for conveying preforms including at least one principal wheel and one auxiliary wheel at least one of which is driven in rotation to move at least one transport device to which are connected in movement holding device each configured to cooperate with a preform, said holding device being adapted to be actuated relative to a preform—or vice versa—between an inactive position and an active holding position, wherein said principal wheel of the conveyor device includes electric actuators that selectively drive at least in rotation said holding device about the central elongate axis thereof in such a manner as to directly and rotationally index said preform in a reference position.
