ABSTRACT:
A liquid-dispenser and surface applicator for sheet stock or other such workpieces, including an applicator member which preferably comprises at least one generally hollow elongated roller which contacts advancing workpieces and applies liquid to surfaces thereof as they pass. A cyclically repeatable liquid-dispensing apparatus meters predetermined pulsed quantities of the liquid from a source and these are coupled to a dispensing tube disposed within and extending axially along the inside of the applicator roller. The dispensing tube has a closed end which causes the pulses of liquid coupled to it to be pressurized and thus expelled as a spray in metered quantities through a series of spaced apertures in the dispensing tube. The sprayed liquid passes into the hollow interior of the roller and the outer wall of the roller is perforate in nature, whereby the sprayed liquid passes through the wall and is absorbed by a resiliently compressible, liquid-transmissible outer cover, throughout which the liquid becomes dispersed for application to the advancing workpieces by direct contact with them.
