| 摘要 |
The invention concerns a device for implementing a blow moulding method providing a better distribution of operating power, comprising several modules (11, 12, 13) connected by a continuously driven conveyor belt (14). Each module comprises a furnace (17) heating preforms, a transfer wheel (18), means (19) transferring preforms from the conveyor belt onto the transfer wheel, a press (20) moulding objects from the preforms and a member unloading (21) the moulded objects. Preforms are brought in the proximity of all the modules by means of the conveyor belt, then two preforms are brought on each transfer wheel module. In order to stagger the high power-consuming steps, such as opening the press and blowing the objects from the heated preforms, the method consists in modifying the travel distance between the preform loading point and the transfer means and/or between the transfer means and the press opening point or both distances from one of the modules to the other simultaneously.
