1. An apparatus for manufacturing an insulating pipe section, wherein the apparatus comprises:
a rotatable longitudinal mandrel configured for receiving and winding uncured mineral wool around the mandrel to manufacture an insulating pipe section;
a belt;
at least two longitudinal jaws engaging the belt, wherein the two jaws are configured to move between an open position and a closed position where the jaws are configured for substantially surrounding the mandrel with the belt; and
a mandrel controlling element configured for actively controlling a transverse movement of the mandrel.
