Vibrator for pipes produced in molds has ring-shaped body, with top and bottom belt as annular discs joined by arms

摘要

The production machine for socket pipes consists of a hollow mold (2) with longitudinal axis pointing in the direction of gravity along which lies an underneath socket mold section (8). At least one vibrator (15) and ring shaped body (14) transmit vibrations into the socket mold section. The ring-shaped body and vibrator form a structural unit with through-passage of diameter greater than the minimum internal width of the socket mold section. The ring-shaped body has a top (16) and bottom (17) belt in the form of annular discs joined by arms (18,19).
