DEVICE AND METHOD FOR DETERMINING THE FRICTION BETWEEN PLASTIC HOLLOW BODIES OF THE SAME MATERIAL COMPOSITION

摘要

A device (1) and a method for determining the friction between plastic hollow bodies (2) with the same material composition. For this purpose, at least one plastic hollow body (2S) is rigidly clamped in parallel to its longitudinal axis (LS) by means of bilateral clamping jaws (4). A linearly moveable plastic hollow body (2B) lies on the plastic hollow body (2S). The linearly and not in parallel to the longitudinal axis moveable plastic hollow body (2B) is impinged with a force (FG). The moveable plastic hollow body (2B) presses with the force (FG) onto the rigidly clamped plastic hollow body (2S). The neck area (3) of the moveable plastic hollow body (2B) is connected with a force measurement unit (6).
