The invention relates to an oven in a production facility for thermoplastic receptacles, comprising a conveyor chain which is provided with gripping devices (16), whereby each gripping device engages axially with the neck of a receptacle blank in order to transport it into the oven. The invention is characterized in that the gripping devices are displaced axially by means of a mechanism which is provided with an arm (44) which can move along a path that is substantially parallel to the axial direction (An) in which gripping takes place and which bears an interface element (40) which is designed to come into contact with the gripping device (30). The invention is further characterized in that the interface element (40) is moveably mounted on the arm (44) to enable slip-free contact with the gripping device while it is immobilized in relation to the arm according to the axial direction in which gripping occurs.
Image L'invention propose un four pour une installation de fabrication de récipients thermoplastiques, du type comportant une chaîne de transport munie de dispositifs de préhension (16) dont chacun est destiné à s'engager axialement sur le col d'une ébauche du récipient pour la transporter dans le four, caractérisé en ce que les dispositifs de préhension sont déplacés axialement par un mécanisme pourvu d'un bras (44) qui est mobile selon une trajectoire sensiblement parallèle à la direction axiale (An) de préhension et qui porte un organe d'interface (40) destiné à venir au contact du dispositif de préhension (30), et en ce que l'organe d'interface (40) est monté mobile sur le bras (44) de manière à permettre un contact sans glissement avec le dispositif de préhension tout en étant immobilisé par rapport au bras selon la direction axiale de préhension.
