ABSTRACT:
A doctor blade holder has two holder parts (4, 5) to clamp a doctor blade (3) with a straight edge therebetween. The holder parts define opposed holder surfaces (6, 7), which, at least in part, form surfaces of an elliptical cylinder which has a cross-sectional form in the shape of an ellipse (Z) which has a longitudinal axis (B--B) which intersects the longitudinal axis (A--A) of the cylinder by an angle of inclination (.alpha.) which, customarily, is in the order of between 0.1.degree. to 1.degree., but may be substantially larger. The minor half-axis of the ellipse (Z) is equal to the radius (r) of the printing machine cylinder (1) and the major half-axis of the ellipse (Z) is longer than the length (1) of the printing machine cylinder against which the doctor blade edge is engaged.
