<p>A device for automatically adjusting conditioner metering roll liquid film thickness. The device comprising a transfer roll (102,103) that mates with a back-up roll (104,105) to form a nip (106,107) through which a sheet passes for wetting a side of it. A metering roll (108,109) mates with the transfer roll (102,103) and has a portion thereof positioned in a liquid filled sump (110) for liquid to be added to an outside surface thereof. An optical sensor (140) is positioned to detect light reflected from the liquid on the outside surface of the metering roll (108,109) and gives off a signal that is received by a controller (90) that actuates a stepper motor (112,113) to move the metering roll (108,109) in a predetermined direction until the correct liquid thickness is obtained on the surface of the metering roll (108,109). <IMAGE></p> |
