| 摘要 |
The invention relates to a system of conveyance for a blowing installation for thermoplastic containers, comprising a series of conveyor elements (24) which are fitted with a gripper device (26, 28), whereby each gripper device can move in an axial direction in relation to the conveyor element (24) on which it is borne in order to become axially engaged on the neck (12) of the blank (10).An external radial collar (14) enables said blank (10) to rest upon a bearing surface (23). The invention is characterized in that each conveyor element (24) comprises a stabilizer (34) which can move in an axial direction from a high retracted position to a low position in order to bear upon the blank (10) so that it can be pressed against the bearing surface (23) before the gripper device (26,28) engages with the collar (12).
