Abstract
A method of monitoring the production of extruded composite profiles by an extrusion head fed by a plurality of worm extruders in which, immediately after the profile has been extruded, it is monitored by spacing measurement devices which determine the spacing between the devices and the profile. The measured spacing is then transmitted to a regulator or governor and compared with a pre-selected value. The governor or regulator controls the worm speed of the individual extruders and, if the measured value differs from the pre-selected value, alters the worm speed of one or more of the individual extruders until the measured value is the same as the pre-selected value.
