Abstract
Abstract An applicator assembly for applying a liquid substance to at least one face of sheet material moving along a predetermined path comprising a housing defining a reservoir for the liquid substance, means for maintaining a predetermined level of the liquid substance in the reservoir, a roll member having at least one circumferentially extending pad mounted on its outer surface, means for rotatably mounting the roll member in said housing comprising vertical trackways in opposed end walls of said housing which in the operative position limit lateral movement of said roll assembly, and a doctor blade made of resilient material mounted along one edge of the housing having a plurality of longitudinally spaced openings therein adapted to engage and wipe said pads whereby a uniform predetermined quantity of liquid substance is applied to the sheet material irrespective of rotational speed of the roll member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
168 words
An applicator assembly for applying a liquid substance to at least one face of sheet material moving along a predetermined path comprising a housing defining a reservoir for the liquid substance, means for maintaining a predetermined level of the liquid substance in the reservoir, a roll member having at least one circumferentially extending pad mounted on its outer surface, means for rotatably mounting the roll member in said housing comprising vertical trackways in opposed end walls of said housing which in the operative position limit lateral movement of said roll assembly, means normally urging said roll member in a direction toward said one face of said sheet material to maintain a predetermined pressure applying relation therewith, and a doctor blade made of resilient material mounted along one edge of the housing having a plurality of longitudinally spaced openings therein adapted to engage and wipe said pads whereby a uniform predetermined quantity of liquid substance is applied to the sheet material irrespective of rotational speed of the roll member.
Claim 2
Dependent Claim
168 words
An applicator assembly for applying a liquid substance to at least one face of sheet material moving along a predetermined path comprising a housing defining a reservoir for the liquid substance, means for maintaining a predetermined level of the liquid substance in the reservoir, a roll member having at least one circumferentially extending pad mounted on its outer surface, means for rotatably mounting the roll member in said housing comprising vertical trackways in opposed end walls of said housing which in the operative position limit lateral movement of said roll assembly, means normally urging said roll member in a direction toward said one face of said sheet material to maintain a predetermined pressure applying relation therewith, and a doctor blade made of resilient material mounted along one edge of the housing having a plurality of longitudinally spaced openings therein adapted to engage and wipe said pads whereby a uniform predetermined quantity of liquid substance is applied to the sheet material irrespective of rotational speed of the roll member.
Claim 3
Dependent Claim
38 words
An applicator assembly as claimed in claim 1 wherein said roll member is completely enclosed so that it is adapted to float in said liquid substance and providing said means for urging said roll member in said direction.
Claim 4
Dependent Claim
22 words
An applicator assembly as claimed in clAim 1 wherein said pad is made of a closed cell neoprene which is nitrogen filled.
Claim 5
Dependent Claim
62 words
An applicator assembly as claimed in claim 1 wherein each of said trackways at opposite ends of said housing is defined by a pair of spaced apart post members mounted on the inner end wall, said trackway at the upper end of said housing being closed by a block member to limit the upward movement of said roll assembly in the trackways.
Claim 6
Dependent Claim
79 words
An applicator assembly as claimed in claim 4 wherein said roll member is hollow and mounts stub shafts at opposite axial ends and wherein the lower terminal edge of said post members are outwardly tapered, the tapered edge of each post being located a predetermined distance from the bottom and side wall of the housing so as to engage the stub shaft when the hollow roll member is submerged at the lower portion of said housing for storage purposes.
Claim 7
Dependent Claim
22 words
An applicator assembly as claimed in claim 4 including means for urging said roll member in a direction toward said block member.
Claim 8
Dependent Claim
38 words
An applicator assembly as claimed in claim 1 including means for continuously supplying the liquid substance to said reservoir and including a gravity discharge port for automatically maintaining a predetermined level of said liquid substance in said reservoir.
Claim 9
Dependent Claim
65 words
An applicator assembly as claimed in claim 1 including a second transfer roll member rotatably mounted in said housing at least partially submerged in said liquid substance, and biasing means urging said transfer roll member toward said applicator roll to effect transfer of liquid substance from said transfer roll to said applicator pad and providing said means for urging said roll member in said direction.
Claim 10
Dependent Claim
25 words
An applicator assembly as claimed in claim 8 including a release plate detachably secured to said housing to maintain the roll members in said trackway.
Claim 11
Dependent Claim
20 words
An applicator assembly as claimed in claim 9 wherein said release plate mounts a stop member aligned with said trackway.
