OFFLINE ROLL TO ROLL WEB COATING

Abstract: a coating system for coating a web of paper includes spaced apart support rollers, a guide roller, a tension roller, a motor, a dispenser, and a control system. the support rollers support respective spools of paper. the guide roller is configured for guiding the paper along a path between the spools of paper. the tension roller is positioned along the path and is configured to engage the paper. the motor is operable to rotate the support rollers and/or the tension roller. the dispenser is fixed proximal to the path and is operable to guide liquid coating onto the paper located on the path. the control system is in communication with the motor and is configured to direct the motor to cause the paper to shift in either direction along the path between the spools.
