ABSTRACT:
An apparatus controls the pressure of a doctoring means against an applicator surface to compensate for charges in the ambient temperature. The apparatus comprises a set of jaws which bring the doctoring means to pressure contact with the applicator surface upon closing and a means for limiting the closing of the jaws at lower temperatures to provide doctoring under reduced pressure at lower temperatures.
