ABSTRACT:
A doctor blade and baseplate are adjustable to define a desired gap therebetween. The doctor blade is fixed in position, gap adjustment being effected by movement of the baseplate. Initial setting-up and levelling are effected by turnbuckles moving a supporting bar. The base plate is slidable vertically on the supporting bar via a pin-and-slot connection. Fine gap adjustment during operation is by screw jacks connected between the supporting bar and the baseplate and operated by a common driveshaft.
