Abstract
A method of controlling a device for conveying thermoplastic material preforms for use in a heat treatment oven and such a 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. In example embodiments, the holding device is adapted to be actuated relative to a preform- or vice versa-between an inactive position and an active holding position. In example embodiments, the at least one principal wheel of the conveyor device includes electric actuators that selectively drive at least in rotation the holding device in such a manner as to index said preform in a reference position.
