ABSTRACT:
In a machine for corrugating a continuous length of strip stock fed between a pair of corrugation rollers, apparatus controls height of corrugations formed by the rollers by selectively varying tension on the strip stock fed between the rollers. Such apparatus includes a sensor for measuring actual height of corrugations formed by the rollers, and a clutch for applying tension to the strip stock upstream of the rollers, with the height of corrugations varying as a direct function of tension applied to the strip stock. A tension sensor is positioned between the clutch and the forming rollers for measuring tension applied to the strip stock and controlling the clutch accordingly.
