摘要
An apparatus for monitoring the production of elongate profiles which are formed from one or more mixtures of rubber or thermoplastics material in an extrusion head which is fed by one or more extrusion devices. The profile passes through a cooling zone in which longitudinal shrinkage of the profile occurs. The actual shrinkage is monitored and compared with desired shrinkage by a control device which controls the drive means for the extrusion devices. The profile also passes over a weighing device which determines the weight per unit length thereof, with the weighing device also being operatively connected to the regulating or control means. If a deviation from the desired shrinkage in the zone or station is ascertained, the regulating device sets a new, corrected, desired weight per unit length value to be achieved at the weighing device. To achieve this desired weight per unit length, the drives for the extrusion devices are each adjusted by a uniform amount by the regulating or control device. By achieving the desired weight value, the desired amount of shrinkage in the cooling path or station is achieved.
