ABSTRACT:
A fountain assembly for applying a fluid composition uniformly to the circumferential surface of a rotating transfer roller. The assembly has an elongated plastic frame having a concave channel formed on one side of it and a rigid metal brace on the other side. A pair of doctor blades is attached to opposite sides of said channel and positioned to contact the surface of the transfer roller. A pair of curved radial surface seals form a resilient bulkhead with the ends of said doctor blades to form a seal with the roller. The radial surface seals, doctor blades and concave channel form a closed chamber when positioned against the transfer roller. A pivot supports the fountain assembly, alternately swiveling said fountain assembly toward and away from the transfer roller. Means are provided for supplying a fluid composition into the channel. In one embodiment, air cylinders are mounted between the pivoting support and frame for adjusting the position of said fountain assembly by thrusting the frame into and out of contact with the transfer roller. In another embodiment, washing nozzles are disposed along the channel for spraying a washing solution to the channel via an internal manifold within the frame for directing a washing fluid to the nozzles and dispensing a controlled amount of a washing solution under pressure through the manifold and nozzles.
