Glue roller assembly

Claim 2

A glue roller and reservoir apparatus adapted for continuous circulation of adhesive comprising: a vessel having a bottom wall and upstanding marginal sidewalls, a stationary rod member upstanding from said bottom wall, a hollow sleeve telescopically disposed about said rod defining an annular passageway therebetween, the lower end of said sleeve including means fluidly connecting said vessel and said passageway, said sleeve having an aperture therein proximate the upper end of said rod, said sleeve being axially rotatable, said sleeve having a plurality of vertically spaced grooves formed to extend about its exterior surface, said grooves defining therebetween spaced ''''land'''' regions, an upstanding bar mounted alongside said sleeve, said bar having an edge facing said roller which contains a plurality of notches defining teeth therebetween, and means for urging fluid in said vessel into said annular passageway upwardly therethrough and through said aperture to drain by gravity down the exterior grooved surface of said sleeve returning to said vessel, said means comprising a shaped or contoured configuration on one of said rod member and the inner surface of said hollow sleeve whereby rotation of said sleeve in the appropriate direction coupled with the contoured configuration will cause said adhesive to move upwardly within said annular passageway to the upper end of said rod and through said aperture to the exterior grooved surface of said hollow sleeve.

Claim 3

Apparatus as claimed in claim 1, wherein said notches are deeper than said grooves.

Claim 4

Apparatus as claimed in claim 2, wherein said bar is pivotable about its vertical axis to move said teeth on said bar towards or away from said grooves.

Claim 5

Apparatus as claimed in claim 3, which includes spring means normally urging said bar to pivot as to urge said teeth into contact with the bottom of said grooves.

Claim 6

Apparatus as claimed in claim 1, which includes a blade and means for selective and adjustable transverse securement in any given position where a vertical edge of said blade overlies a portion of the depth of said notchEs whereby rotation of said glue roller carrying glue on said glue roller will cause a portion of said glue to be ''''doctored off'''' by said blade edge, thereby controlling the thickness of the glue lines on said glue roller.

Claim 7

Apparatus as claimed in claim 1, which includes means for moving an article in tangential relationship with the exterior surface of said glue roller whereby a plurality of deposits of glue are transferred from said ''''land'''' regions to said article.

Claim 8

Apparatus as claimed in claim 1, which includes at least one springlike finger member mounted with a terminal end riding in one of said grooves and being pointed in a direction opposite to the normal operational rotation of said roller.

Claim 9

The apparatus as claimed in claim 7, wherein said finger member is mounted in a support having internal heat means.

Claim 10

In a label handling apparatus comprising: a horizontal baseplate, means upstanding from said plate defining a reservoir for a plurality of labels, tickets or the like stacked on edge in mutually flush, registering relationship, said reservoir means including a gateway adapted to allow an end segment of a label proximate thereto to move out of flush abutment with the remainder of said labels, an upstanding transfer roller, adapted for rotation about its vertical axis, located proximate said gateway and spaced slightly outside said reservoir area, a glue applicator located in spaced relationship with said transfer roller on a line extending away from said gateway and means for delivering a pulse of air across said gateway and at the same time tangentially across the surface of said transfer roller, thereby urging the end segment of the closest label out of flush contact with the remainder of said labels and toward said transfer roller and thence by said transfer roller to said glue applicator; the improvement wherein said glue applicator comprises: a vessel having a bottom wall and upstanding marginal sidewalls, a stationary rod member upstanding from said bottom wall, a hollow sleeve telescopically disposed about said rod defining an annular passageway therebetween, the lower end of said sleeve including means fluidly connecting said vessel and said passageway, said sleeve having an aperture therein proximate the upper end of said rod, said sleeve being axially rotatable, said sleeve having a plurality of vertically spaced grooves formed to extend about its exterior surface, said grooves defining therebetween spaced ''''land'''' regions, an upstanding bar mounted alongside said sleeve, said bar having an edge facing said roller which contains a plurality of notches defining teeth therebetween, and means for urging fluid in said vessel into said annular passageway upwardly therethrough and through said aperture to drain by gravity down the exterior grooved surface of said sleeve returning to said vessel, said means comprising a shaped or contoured configuration on one of said rod member and the inner surface of said hollow sleeve whereby rotation of said sleeve in the appropriate direction coupled with the contoured configuration will cause said adhesive to move upwardly within said annular passageway to the upper end of said rod and through said aperture to the exterior grooved surface of said hollow sleeve.

Claim 11

In a label handling apparatus comprising: a horizontal baseplate, means upstanding from said plate defining a reservoir for a plurality of labels, tickets or the like stacked on edge in mutually flush, registering relationship, said reservoir means including a gateway adapted to allow an end segment of a label proximate thereto to move out of flush abutment with the remainder of said labels, an upstanding transfer roller, adapted for rotation about its vertical axis, located proximate said gateway and spaced slightly outside said reservoir area, a glue applicator located in spaced relationship with said transfer roller on a line extending away from said gateway and means for delivering a pulse of air across said gateway and at the same time tangentially across the surface of said transfer roller, thereby urging the end segment of the closest label out of flush contact with the remainder of said labels and toward said transfer roller and thence by said transfer roller to said glue applicator; the improvement wherein said glue applicator comprises: a vessel having a bottom wall and upstanding marginal sidewalls, a stationary rod member upstanding from said bottom wall, a hollow sleeve telescopically disposed about said rod defining an annular passageway therebetween, the lower end of said sleeve including means fluidly connecting said vessel and said passageway, said sleeve having an aperture therein proximate the upper end of said rod, said sleeve being axially rotatable, said sleeve having a plurality of vertically spaced grooves formed to extend about its exterior surface, said grooves defining therebetween spaced ''''land'''' regions, an upstanding bar mounted alongside said sleeve, said bar having an edge facing said roller which contains a plurality of notches defining teeth therebetween, and means for urging fluid in said vessel into said annular passageway upwardly therethrough and through said aperture to drain by gravity down the exterior grooved surface of said sleeve returning to said vessel, said means comprising a shaped or contoured configuration on one of said rod member and the inner surface of said hollow sleeve whereby rotation of said sleeve in the appropriate direction coupled with the contoured configuration will cause said adhesive to move upwardly within said annular passageway to the upper end of said rod and through said aperture to the exterior grooved surface of said hollow sleeve.
