Abstract
Abstract A tape applicator for selectively advancing one, two or more strips of tape from rolls mounted thereto and having a cutter assembly which can selectively cut one, two or more of the tape strips being applied. The tape advancement initiation device includes first and second rollers which are selectively brought into abutting engagement so as to grip a strip of tape depending therebetween and at least one of the rollers is selectively rotated to advance the tape gripped between the rollers. The rollers defining the tape advancement initiation device are preferably separated into at least first and second roller sections which are selectively independently rotatable to selectively independently advance select tape strips mounted to the apparatus. Similarly, the cutter assembly provided to cut the tape through foot pedal actuation is preferably divided into at least first and second sections which are independently selectively operable by respective foot pedal actuators so as to selectively independently cut a particular strip of tape being applied by the apparatus.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
221 words
An apparatus for applying tape to a paved surface comprising: a main frame having at least first and second wheel means for advancing said main frame along a paved surface to be marked; means for rotatably carrying at least one roll of tape to be applied; a tape applying roller mounted for pressing tape dispensed from said at least one roll of tape against the paved surface; means for selectively advancing tape from at least one of said at least one roll of tape towards the paved surface, said tape advancing means including first and second rollers, at least one of said rollers being mounted for selective movement into engagement with the other of said rollers and means for rotating at least one of said rollers at least when said rollers are in engagement whereby a strip of tape depending between said rollers will be advanced by rotation of said at least one roller, said means for rotating at least one of said rollers comprising a ratchet and pawl assembly operatively coupled to a shaft of said roller so as to selectively rotate said roller about the longitudinal axis thereof in one direction while prohibiting rotation in the opposite direction; and means for cutting a strip of tape extending at least between said tape advancing means and said tape applying roller.
Claim 2
Independent Claim
221 words
An apparatus for applying tape to a paved surface comprising: a main frame having at least first and second wheel means for advancing said main frame along a paved surface to be marked; means for rotatably carrying at least one roll of tape to be applied; a tape applying roller mounted for pressing tape dispensed from said at least one roll of tape against the paved surface; means for selectively advancing tape from at least one of said at least one roll of tape towards the paved surface, said tape advancing means including first and second rollers, at least one of said rollers being mounted for selective movement into engagement with the other of said rollers and means for rotating at least one of said rollers at least when said rollers are in engagement whereby a strip of tape depending between said rollers will be advanced by rotation of said at least one roller, said means for rotating at least one of said rollers comprising a ratchet and pawl assembly operatively coupled to a shaft of said roller so as to selectively rotate said roller about the longitudinal axis thereof in one direction while prohibiting rotation in the opposite direction; and means for cutting a strip of tape extending at least between said tape advancing means and said tape applying roller.
Claim 3
Dependent Claim
72 words
An apparatus as in claim 1, wherein said at least one of said rollers which is rotated includes at least first and second roller sections selectively independently rotatable by a respective ratchet and pawl assembly and wherein first and second control arms are provided for selectively operating each said ratchet and pawl assembly whereby one portion of said advancing means will advance tape independently of the remaining portion of the advancing means.
Claim 4
Dependent Claim
50 words
An apparatus as in claim 1, wherein one of said rollers is slidable longitudinally relative to said main frame by means of a spring biased rod coupled to a longitudinal shaft of said one of said rollers so as to selectively move into engagement with the other of said rollers.
Claim 5
Dependent Claim
58 words
An apparatus as in claim 3, wherein said ratchet and pawl assembly is operatively coupled to said spring biased rod such that operation of said ratchet and pawl assembly to rotate said at least one of said rollers causes said spring biased rod to urge said at least one of said rollers into engagement with the other roller.
Claim 6
Dependent Claim
72 words
An apparatus as in claim 3, wherein said at least one of said rollers which is rotated includes at least first and second roller sections selectively independently rotatable by a respective ratchet and pawl assembly and wherein first and second control arms are provided for selectively operating each said ratchet and pawl assembly whereby one portion of said advancing means will advance tape independently of the remaining portion of the advancing means.
Claim 7
Dependent Claim
47 words
An apparatus as in claim 1, wherein said cutting means comprises a plurality of blade members mounted for sliding movement along a portion of the longitudinal axis of said apparatus so as to engage and cut tape extending between said advancing means and said tape applying roller.
Claim 8
Dependent Claim
45 words
An apparatus as in claim 6, wherein said cutting means includes first and second cutting blade assemblies, selectively independently operable by means of a respective pedal, each said pedal being spring mounted to said main frame so as to be biased into an inoperative position.
