ABSTRACT:
A method for monitoring deviations in the dimensions of profile strips during production is disclosed, as is an apparatus suitable for carrying out the method. The profile strip is formed from one or more rubber or thermoplastic material mixtures which are fed from one or more extrusion devices through nozzles into a common nozzle in an extrusion head. Pressure and temperature measuring means measure the extrusion pressure and temperature of each mixture. The profile strip thus produced then passes over weighing device which measures its weight per unit length. The measured value is transmitted to a regulating or control device and compared with a desired weight per unit length. When a deviation is ascertained, the regulation or control device which is also operatively connected to the pressure and temperature means and to adjustable drives for each extrusion device, compared the measured extrusion pressure and temperature values with desired values and adjusts the drive of one or more of the extrusion devices to cause the measured pressure and temperature values, and hence the measured weight per unit length, to be restored to their desired values.
