Abstract
Abstract A tape dispenser applicator including a body having spacers located a substantial distance above the lower end of the body for spacing the dispensing plane of the side edges of the tape from an adjacent side wall. The spacers permit free rotation of the spool from which the tape is dispensed. A pressure pad is also provided for applying a bonding pressure to the tape immediately behind the first applicator roller to ensure that the tape is firmly secured prior to cutting of the end of the tape. A cutter blade assembly is also provided in advance of the body for cutting the tape in response to movement of the body towards an abutting end wall. The cutter assembly includes a cutter bar disposed on one side of the path of the tape and a cutter blade disposed on the other side of the path of the tape, the cutter bar and cutter blade cooperate with one another to cut the tape in use. The location of the cutter blade assembly with respect to the first applicator roller is such that when the tape is cut, a sufficient length of tape projects beyond the first applicator roller to permit the tape to extend to the wall which caused the cutting action to take place. In addition, a small rotary brush assembly is provided in advance of the first applicator roller to clean the ledge on which the tape is applied immediately before the application of the tape.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
213 words
A tape dispenser applicator for dispensing and applying a tape to a ledge projecting outwardly from a substantially planar surface comprising: a. a body having an upper end and a lower end, b. a body having means for mounting a tape spool for unwinding rotation thereon with an edge of the spool disposed in an exposed outwardly directed first plane at one side of said body, c. said body having applicator roller means for guiding and unwinding a tape in an application path with the outer edge of the unwinding tape disposed in said first plane, said applicator guide roller means including at least one applicator roller located at the lower end of said body for receiving and unwinding tape and applying the tape to a ledge in use, d. spacer means located a substantial distance above the lower end of said body for spacing said first plane outwardly from said planar surface whereby said tape is free to unwind without frictional interference from said planar surface, and e. pressure plate means mounted on said body rearwardly of said applicator roller for movement with respect to said body toward and away from said ledge to apply a pressure to a portion of an unwinding tape downstream of and adjacent said first applicator roller.
Claim 2
Dependent Claim
213 words
A tape dispenser applicator for dispensing and applying a tape to a ledge projecting outwardly from a substantially planar surface comprising: a. a body having an upper end and a lower end, b. a body having means for mounting a tape spool for unwinding rotation thereon with an edge of the spool disposed in an exposed outwardly directed first plane at one side of said body, c. said body having applicator roller means for guiding and unwinding a tape in an application path with the outer edge of the unwinding tape disposed in said first plane, said applicator guide roller means including at least one applicator roller located at the lower end of said body for receiving and unwinding tape and applying the tape to a ledge in use, d. spacer means located a substantial distance above the lower end of said body for spacing said first plane outwardly from said planar surface whereby said tape is free to unwind without frictional interference from said planar surface, and e. pressure plate means mounted on said body rearwardly of said applicator roller for movement with respect to said body toward and away from said ledge to apply a pressure to a portion of an unwinding tape downstream of and adjacent said first applicator roller.
Claim 3
Dependent Claim
64 words
A tape dispenser applicator as claimed in claim 1 wherein said applicator guide roller means includes a second applicator roller at the lower end of said body rearwardly of said first applicator roller for receiving and guiding an unwinding tape in an application plane extending between said rollers, said pressure pad means being mounted on said body intermediate said first and second roller means.
Claim 4
Dependent Claim
61 words
A tape dispenser applicator as claimed in claim 2 including handle means mounted on said body and pressure pad actuator lever means pivotally mounted on said body and having a manually engageable free end disposed adjacent said handle means whereby said pressure pad may be activated by hand of the operator used to engage the handle for movement of the device.
Claim 5
Dependent Claim
65 words
A tape dispenser applicator as claimed in claim 1 including cutter means projecting forwardly from said body and operable in response to engagement with a wall obstructing forward movement of the body to cut the tape being dispensed upstream of said applicator roller means a distance equal to the distance between the lower face of the applicator roller means and the obstructing wall in use.
Claim 6
Dependent Claim
102 words
