Abstract:
A temperature condition oven for a blow-molding facility for producing containers of thermoplastic material, comprising:a conveyor chain of links having gripping devices each of which is intended to carry a blank of the container to move it around a circuit inside the oven, with the chain being driven in continuous movement along its circuit, wherein each gripping device is axially movable with respect to the link that carries it so that when it is taken from an extreme release position to an extreme gripping position it engages axially on the neck of the blank, the oven further comprising means for controlling the movements of the gripping devices between their release and gripping positions, wherein the means for controlling the movements of the gripping devices comprises at least one mechanism provided with an arm that is movable along a trajectory that is essentially parallel to the axial direction of gripping and which carries an interface device that comes into contact with the gripping device, with the interface device movably mounted on the arm in such a way as to allow non-slip contact with the gripping device while being immobilized with respect to the arm along the axial direction of gripping.
