ABSTRACT:
Lateral escape of ink from between the end face (A) of a duct roller (1) and the side wall (3) retaining the duct roller is prevented by extending the length of the duct blade (11) beyond the axial extent of the duct roller and placing an end wall portion (4) in the end wall which is resiliently pressed against the end face (A) of the duct roller and, further, resiliently engaged with the top face of the duct blade (11) to form a tight seal and prevent escape of ink laterally from between the duct blade (11) and the duct roller (1). The resilient portion is plate-like, and the sealing strip preferably is a generally T-shaped element, in which the leg portion of the T is clamped to both the resilient portion (4) of the end wall and the fixed portion (3) thereof, while permitting relative movement of the two elements.
