摘要： An auxiliary device and a method for finishing and calibrating preforms that are removed from a multiple tool in an unstable shape, the calibration process being performed with compressed air immediately after removing and withdrawing the preforms from the multiple tool. Nipples that can be inserted into the preforms are provided with expandable press rings or sealing rings in order to seal the interior of the blow-molded part of the preforms. The compressed air is introduced via the nipples, the sealing process being performed by radially expanding the press rings or sealing rings in analogy to the closing process of thermoses, thus protecting the preforms from adverse forces. The sealing point can be randomly selected in the transition zone from the threaded part to the blow-molded part of the preforms. The interior of the blow-molded part is optimally sealed without affecting the form stability and dimensional stability of the preforms.

摘要翻译： 一种用于精加工和校准从不同形状的多个工具中移除的预成型件的辅助装置和方法，在从多个工具中取出和取出预制件之后，立即用压缩空气进行校准过程。 可插入预成型件的接头设置有可膨胀的压环或密封环，以密封预成型件的吹塑成型部分的内部。 压缩空气通过接头引入，密封过程通过类似于热电偶的闭合过程径向膨胀压环或密封环来进行，从而保护预制件免受不利的影响。 密封点可以在从预成型件的螺纹部分到吹塑成型部分的过渡区域中随机选择。 吹塑部件的内部是最佳密封的，而不影响预制件的形状稳定性和尺寸稳定性。

摘要： A method and an apparatus for rapid and efficient heating of polymer pellets in preparation for processing in a plastifier. For introduction of heat energy, a gas, preferably dried air, is introduced into the polymer pellets flow so as not to be in direct countercurrent thereto. The gas is preferably introduced in its still hottest state in a targeted fashion, for the purpose of rapid energy input, at a freely selectable location. This preferably takes place at the material output of the booster hopper. The gas is preferably conducted by way of cascades, which can be of a variable design, and flows through the bulk material at least twice. The speed of the flow can be influenced.
