An apparatus for the conditioning of plastics material pre-forms with a tempering space for receiving a plurality of plastics material pre-forms, with a supply device a removal device, and a conveying device which conveys the plastics material pre-forms from the supply device to the removal device in such a way that each plastics material pre-form remains in the tempering space for a preset duration of the dwell period. The temperature of the plastics material pre-forms upon leaving the removal device is substantially constant irrespective of a duration of the dwell period of the plastics material pre-forms in the tempering space and the conveying device is designed in such a way that each plastics material perform remains in the tempering space for a period of time of at least five minutes.

Apparatus and method of producing plastics material containers

A device () and a method for determining the friction between plastic hollow bodies () with the same material composition. For this purpose, at least one plastic hollow body (S) is rigidly clamped in parallel to its longitudinal axis (LS) by means of bilateral clamping jaws (). A linearly moveable plastic hollow body (B) lies on the plastic hollow body (S). The linearly and not in parallel to the longitudinal axis moveable plastic hollow body (B) is impinged with a force (F). The moveable plastic hollow body (B) presses with the force (F) onto the rigidly clamped plastic hollow body (S). The neck area () of the moveable plastic hollow body (B) is connected with a force measurement unit ().
