Abstract:
System of conveyance for a blowing installation for thermoplastic containers, of the type that comprises a series of conveyor elements (24) fitted with at least one gripper device (26, 28) conceived to carry a blank (10) of the container in order to make it circulate along a path inside the installation, of the type in which each gripper device (26, 28) moves in an axial direction in relation to the conveyor element (24) that carries it so that when it is brought from a cleared high position to a low gripped position, it engages in an axial direction with the neck (12) of the blank (10), where the blank (10) then rests by an external radial collar (14) on a bearing surface (23),characterized by the fact that each conveyor element (24) comprises a stabilizer (34) that moves in an axial direction from a high retracted position to a low position to come and rest on the blank (10) in order to press it against the bearing surface (23) before the gripper device (26, 28) engages with the neck (12).
