摘要:
The invention concerns a mold-carrier unit for a thermoplastic container blowing machine. The mold-carrier unit is designed to equip a machine for making containers obtained by blow-molding, and optionally by elongation, based on a thermoplastic preform. The unit comprises at least one rotatable mobile panel (3, 5), bearing articulating lugs on a first edge and bearing locking lugs (17, 15) on a second edge, the mobile panel including at least one rib (31, 33, 39; 41, 45, 49) enabling at least one locking lug to be connected with at least one articulating lug such that the rib reinforces the rigidity of the mold-carrier unit.

The invention relates to a station for the stretching/blowing of preforms having an upward-facing open end. The inventive station (100) comprises a bracket (4000) that supports a blow mould, a stretch rod (2700) and means for controlling the movements of the stretch rod (2700). The aforementioned control means comprise: (i) an actuator, and (ii) a roller (4700) and a speed control cam (200), said roller (4700) coming into contact with the speed control cam (200) as the stretch rod (2700) enters the blow mould, thereby controlling the speed with which the stretch rod (2700) enters the blow mould. The invention is characterised in that the speed control cam (200) is disposed below the base (800) of the blow mould.

The invention concerns a transfer line for a preform heating device. Such a heating device is designed for a container blowing machine, each container being formed from a preform. The transfer line is designed for a preform heating device (31) of the type wherein a preform supporting means is mounted on an articulated line with means for driving in rotation the preform when it is being transported in the heating device. The means for driving the preform in rotation comprises a shaft (77) secured to one element (75) of the articulated line (60) and which bears a pinion gear (62) urged to roll along a raceway (63, 65) integral with a frame (79) when said articulated line is driven by motoring means.
