ABSTRACT:
An improved method and apparatus is described for controlling an average dimensional characteristic of an article being extruded. This dimensional characteristic is determined from a predetermined volume of material supplied, from a measured dimensional characteristic and from a known cross sectional configuration. When the measured dimensional characteristic varies from a predetermined value, the volume of the stock material supplied is altered to restore the measured dimensional characteristic to the predetermined value.
