Chamber doctor blade assembly

摘要

A chamber doctor blade assembly includes axially spaced lateral cheeks that seal the ends of the ink reservoir. Each of these lateral cheeks has a sealing face that conforms to the curvature of the screen roller with which the chamber doctor blade is used. These sealing faces are provided with lubricant reservoirs. The lateral faces also have leading edges bent or flared out to form strippers which remove excess beads of ink from the screen roller.
