PURPOSE: To compensate for excess supply of damping water effectively by providing an attachment with two distributing rollers such that both distributing rollers can be driven in the peripheral direction through a damping roller by friction. CONSTITUTION: The frame 1 of an attachment has a vertical mounting plate 14 receiving first and second distributing rollers 18, 19 on the opposite sides and both rollers 18, 19 can be driven through a damping roller 7 by friction. Both rollers 18, 19 are mounted radially of the roller 7 for resilient movement under action of a spring 29 and contact pressure between the roller 7 and both rollers 18, 19 is produced by the weight of the frame 1. A constant pressing force thereby exists constantly and since the frame 1 is received by a mounting lever 3 through a coupling member 10 movably in the radial direction relative to a water distribution cylinder 6, it can be connected or disconnected. Drive mechanisms 22, 23 producing a reciprocal movement in the axial direction are arranged for the frame 1 so that the frame 1 can reciprocate sideways along with the rollers 18, 19. |
