    摘要： A powdered composition capable of being worked on heating is prepared from a PVC, or PVC copolymer, base, an/ impact resistant/ antishock additive, stabilisers and lubricants, by first mixing the additives at a temperature of 40* to 120*C. The mixture is allowed to cool and then dispersed in the PVC base by mixing in the cold. The mixture becomes homogeneous during the heating prior to working.

    摘要： An apparatus for mass producing hollow objects, such as bottles, wherein the objects are formed from molds which are moved along a predetermined path and are injected with a hot plastically deformable material, such as plastic, at a first station along said path. Gas is thereafter blown into the mold thereby forming a hollow object therein. When the object in each mold cools down enough so that it may be removed without self-deformation, it is so removed at a second station along the path. The object is then held apart from, and preferably in tracking relation with, the mold wherein it is further cooled to a lower finishing temperature as the mold continues to move along its path. The object is then released at a third station along said path. By removing each object from a mold before it has cooled to said finishing temperature, such object may be cooled faster and the mold may be refilled more frequently during each operation thereby increasing the output of hollow objects.

    摘要翻译： 一种用于大规模生产中空物品（例如瓶子）的装置，其中物体由沿着所述路径的第一站沿着预定路径移动并且沿着所述路径注入热塑性变形材料（例如塑料）的模具形成。 然后将气体吹入模具中，从而在其中形成中空物体。 当每个模具中的物体冷却下来，使得其可以在没有自变形的情况下被去除，所以在沿着路径的第二站处被去除。 然后将物体与模具分开并且优选地与模具跟踪，其中当模具继续沿其路径移动时，其进一步冷却至较低的完成温度。 然后，物体沿着所述路径在第三站处被释放。 通过在模具冷却至所述最终温度之前将模具中的每一个物体从模具中移出，可以更快地冷却该物体，并且可以在每个操作期间更频繁地再填充模具，从而增加中空物体的输出。
