Open loop heating controller and method for corrugators

摘要: An open-loop method and apparatus for controlling the heating of webs utilized in a corrugating machine production double-face corrugated paperboard as function at least one factor corrugator machine. A rotatably journaled roll receives web contact with circumferential area between is varied by control circuit. The circuit varies positioning positionable means relative to response senses generates signal related sensed factor. generated periodically sampled stored first time. compared time subsequent drive value difference signals applied driving means.
