摘要： A continuous strip coating machine has top (18) and bottom (13) applicator rolls and a backup roll (12) adjacent the top applicator roll (18). A lift roll (38) to lift the strip (10) and thus vary the angle of wrap of strip (10) about the bottom applicator roll (13) is provided. The use of lift roll (38) in turn varies the pressure between strip (10) and roll (13) and thus the thickness of the coating applied to the strip bottom. Thickness may be measured indirectly by measuring the pressure of the strip (10) on the roll (13). Thickness may also be measured directly. Oscillations of the strip (10) in a drying oven (14) may also be sensed and compensated for. Feedback control is used with thickness measuring techniques to control coating thickness by varying angle of wrap, relative speed between the roll (13) and strip (10), and/or nip pressure between roll (13) and transfer roll (28) that transfers coating material to the roll (13).
