Abstract

Abstract An applicator for dispensing a tape coated with an adhesive compound onto a dry wall, particularly along the abutting margins of the dry wall panels, the applicator including a housing containing a reel from which the tape is dispensed, and a chamber through which the tape passes, the chamber having a distributor nozzle which applies a dry wall compound to the tape. The housing carries a set of applicator wheels over which the tape passes; the applicator wheels press the tape flat against the abutting margins of coplanar panels. The adhesive property of the dry wall compound is utilized to draw the tape through the applicator housing. A V-shaped pressing wheel is movable into engagement with the tape for the purpose of applying the tape to angularly disposed panels. The housing carries a tape cutter disposed adjacent the applicator wheels. A valve is provided to control the supply of the compound. Manual controls for the V-shaped pressing wheel and tape cutter are provided adjacent the valve for ready manipulation of the applicator.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 171 words
In a tape applying device, a housing comprising laterally spaced side walls and support means between said side walls for rotatably mounting a roll of tape; a top wall extending between said side walls; a partition wall extending between said side walls below said top wall to define a tape coating chamber, the partition wall having forward and rear end edges spaced from said top wall; a discharge tube extending laterally through said chamber above a portion of said partition wall, said tube having a longitudinal slot therein adjacent the bottom thereof; means for feeding adhesive into said tube; and means for guiding tape from a roll of tape on said support means to extend along a path between the rear end of said partition wall and said top wall, slidably against the bottom of said discharge tube adjacent said slot, then outwardly of said chamber between the forward end of said partition wall and said top wall to a roller on said device for pressing said tape against a surface.
Claim 2
Dependent Claim 171 words
In a tape applying device, a housing comprising laterally spaced side walls and support means between said side walls for rotatably mounting a roll of tape; a top wall extending between said side walls; a partition wall extending between said side walls below said top wall to define a tape coating chamber, the partition wall having forward and rear end edges spaced from said top wall; a discharge tube extending laterally through said chamber above a portion of said partition wall, said tube having a longitudinal slot therein adjacent the bottom thereof; means for feeding adhesive into said tube; and means for guiding tape from a roll of tape on said support means to extend along a path between the rear end of said partition wall and said top wall, slidably against the bottom of said discharge tube adjacent said slot, then outwardly of said chamber between the forward end of said partition wall and said top wall to a roller on said device for pressing said tape against a surface.
Claim 3
Dependent Claim 32 words
A device as defined in claim 1 wherein said top wall is hinged to one of said side walls whereby it may be selectively moved to provide access to said coating chamber.
Claim 4
Dependent Claim 36 words
A device as defined in claim 1 including at least one rod extending between said side walls, the rear end portion of said partition wall being looped over said rod and providing a tape guiding surface.
Claim 5
Dependent Claim 37 words
A device as defined in claim 1 wherein a portion of one of said side walls adjacent said support means is hingedly mounted to provide access to said support means for mounting a roll of tape thereon.
Claim 6
Dependent Claim 31 words
A tape applying means, as defined in claim 1, wherein: a. a tape cutter means is carried by the forward end of the housing to sever the tape at preselected points.
Claim 7
Dependent Claim 32 words
A tape applying means, as defined in claim 5, wherein: a. a manually operable means is mounted on the housing for moving the extended end of the tape over the roller means.
