Abstract
An oven for thermal treating a web includes: an over chamber; a web transport for transporting a web through the oven chamber; a heater for heating the web in the oven chamber; an exhaust system connected to the oven chamber; a model-based controller for controlling the web temperature profile; and an air delivery system. The model-based controller includes: (i) a plurality of sensor inputs; (ii) a plurality of control signal outputs; (iii) a multi-variable controller with first principles guidelines and oven and process boundaries for a first specific oven; (iv) a desire process profile; and (v) a translator module for permitting the desire process profile to be transferred to at least a second specific oven.
