ABSTRACT:
Apparatus for applying liquid to a workpiece surface by contact, including at least one freely rotatable roller having a cylindrical outer wall whose surface is arranged to contact workpieces or workstock, including elongated sheet stock, and to be rotatably moved thereby while transferring liquid to the surface of the workstock or workpiece by contact. The apparatus includes a source or supply of the liquid to be applied and a controllable liquid-dispensing device connected between the source and the roller for conveying desired quantities of liquid from the source to the roller, and also includes means for controlling the liquid-dispensing apparatus in response to roller rotation such that predetermined quantities of liquid are provided from the source in direct relation to the roller movement caused by the advancing workpieces or workstock. In a preferred embodiment, the roller is generally hollow and includes a series of internal spray orifices which discharge the liquid conveyed to the roller from the source outwardly into the interior of the roller, for contact with the inside periphery of the cylindrical roller wall. The roller wall is perforate in nature and has sufficient liquid-carrying capability to transfer the liquid from its inside periphery to its outside periphery while also dispersing it around and along the roller surface for transfer to the advancing workpieces as the roller rotates in contact therewith.
