    摘要: The invention relates to a device for transporting a hollow body provided with a neck, for a hollow body made of a thermoplastic material. The device comprises at least one mounting translatably mobile along a predetermined path, at least one shaft rotatably mounted in the mounting mobile about a predetermined axis, and a member for gripping the hollow body by a neck which is supported by the rotary shaft. The transport device further comprises means for angular indexing of the rotary shaft in a single predetermined indexed angular position in relation to the mounting.

    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 proposes a method for positioning protective screening ramps of a station for heating preforms, on the occasion of a change of format, the heating station comprising:—members for transporting preforms;—at least one pair of parallel longitudinal screening ramps for protecting necks against heat, which ramps are parted in order to leave a slot through which the preforms progress;—a motorized device for moving the ramps transversely. The method includes a preliminary calibration step which consists in arranging at least two calibration elements between the two protective screening ramps occupying an initial position, and manually causing the protective screening ramps to move into a calibrated position in which they are each in simultaneous contact with the two calibration elements.
