    摘要: As described herein, there is provided safety apparatus for continuous rotary blow molding machines of the type wherein the extruder operates independently of the machine to continuously extrude plastic tube through its die head during the interruption of operation by the blow molding machine. The safety apparatus includes a blow tube mounted on the extruder for directing air under pressure against the plastic tube to deflect the tube away from the molds of the molding machine upon interruption of the operation of the blow molding machine. A conveyor, operative at the same time as the blow tube and extending in a direction coincident with the direction of pressurized air, receives the diverted plastic tube and carries the plastic tube to a receptacle. The blow tube and conveyor remain operative at least until the machine is restarted. In order to permit the plastic tube to resume its normal direction of discharge into the molds, there is also provided a cutting device for cutting the plastic tube right at the die head of the extruder a predetermined time after the machine is restarted. Finally, a safety gate, providing access to the molds of the machine when open, includes safety switches which disable the machine when the gate is open.

    摘要翻译: 如本文所述,提供了用于连续旋转吹塑机的安全装置,其中挤出机独立于机器运行,以在吹塑机的操作中断期间通过其模头连续挤出塑料管。 安全装置包括安装在挤出机上的吹管,用于将压力的空气引导到塑料管上,以在吹塑机的操作中断时使管远离模制机的模具。 与吹塑管同时工作并沿与加压空气的方向一致的方向延伸的输送机接收转向的塑料管并将塑料管运送到容器。 吹塑管和输送机至少保持工作直到机器重新起动。 为了允许塑料管恢复其正常的排出方向进入模具,还提供了一种切割装置,用于在机器重新启动之后的预定时间内在挤出机的模头处直接切割塑料管。 最后,安全门在打开时提供对机器的模具的访问,包括当门打开时禁用机器的安全开关。

    摘要: A plastics material bottle is collapsible by applying axial compression, the bottle comprising a cylindrical body having a polygonal cross-section, e.g. a section that is substantially square or rectangular with rounded corners (18), the body being formed with transverse fluting grooves (14) which include fold starters (16) situated in the immediate vicinity of the above-mentioned rounded corners (18). The invention is particularly applicable to bottles for containing beverages such as mineral water, for example.
