摘要： The invention concerns 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, said holding device being adapted to be actuated relative to a preform—or vice versa—between an inactive position and an active holding position, said principal wheel of the conveyor device including electric actuators that selectively drive at least in rotation said holding device in such a manner as to index said preform in a reference position.

摘要： The invention concerns a device for handling preforms for heating units. The device includes a mandrel that defines a rotation axis of the preforms; a tip mounted at an end of the mandrel and having a part penetrating into the neck of the preforms; a rubbing contact rigidly connected to the tip; and a heatsink rigidly connected to the mandrel and intended to come into contact with the tip. The tip also includes a cooling part axially in line with the penetrating part. The cooling part includes at least one thermal exchange raised portion in contact with the surrounding air. Furthermore, the tip is mounted such that it can be mobile on the mandrel.

摘要： A thermal conditioning device for thermally conditioning preforms, comprising a heating module provided with an enclosure with a transport volume for said preforms; a heating means and a cooling means that are oriented toward the volume; a control means for controlling said heating and cooling means; said cooling means comprising a circulating means for circulating a flow of air with a nominal flow rate determined by said control means; a channel between said circulating means and said enclosure and leading toward said volume; wherein it comprises, along said channel, a measuring means for measuring the actual flow rate and an adjusting means for adjusting said nominal flow rate with respect to said actual flow rate, by controlling the control means. The invention also relates to a corresponding thermal conditioning method.

摘要： A heating unit for heating preforms made of plastics material and having a flange separating a body and neck. The heating unit comprising a plurality of supports, each bearing a gripping member for gripping the preforms. The supports are movable in the heating unit such that each gripping member moves along a conveying path of the preforms. The heating unit also comprises a plurality of shells secured to the supports, where each shell is connected to one or more supports by an actuating member. The actuating member is mounted on said support to pivot about an axis situated at a distance from the conveying path of the preforms. The heating unit further comprising means for pivoting the actuating member to drive the shell from an open position to a protection position when the support to which said shell is connected is passing from an admission/releasing zone to a holding zone.

摘要： The invention relates to a unit for molding containers, which comprises two mold supports, a device for locking the mold supports in the closed position, and a bistable device which comprises a fixed element and a mobile element able to move between two stable extreme positions. The mobile element comprises a mobile magnetic dipole, and the fixed element comprises a fixed magnetic dipole, the fixed magnetic dipole applying a magnetic force from a distance to the mobile magnetic dipole in order to force the mobile element toward one or other of its two stable extreme positions.
