ABSTRACT:
In a screen process printing machine, one edge of the doctor blade is firmly held in position against a supporting member. A rigid U-section supporting bar which is secured to the supporting member at one or two points bears on the top face of the active edge of the doctor blade, thus ensuring that the active edge is applied against a rotary cylindrical screen under uniform pressure.
