Abstract
Abstract A pavement-marking tape applicator comprises a carrier which has at least one wheel and an application roller and moves along a paved surface on which a pavement-marking tape is to be applied. A roll of pavement-marking tape is unwindably supported on the carrier. A pair of free end position adjusting rollers are mounted on the carrier for holding the unwound tape at such a position that the tape hangs in front of the application roller. The free end position adjusting rollers are capable of finely adjusting the free end position of the tape. A drive mechanism for manually or electrically rotating these free end position adjusting rollers is provided. In one aspect of the invention the pavement-marking tape applicator comprises a cutter mounted on the carrier for cutting the tape after completion of application of the tape on the paved surface. This cutter comprises a transversely extending rail, a disc-like rotary blade supported on a support member which is slidable on the rail, stationary blade which cuts the tape in association with the rotary blade and an actuating mechanism for actuating the rotary blade support member for sliding movement along the rail.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
A pavement-marking tape applicator comprising: a carrier having at least one wheel and an application roller for engaging a pavement-marking tape and applying the same on a paved surface while rolling on the paved surface; means for supporting a roll of the pavement-marking tape unwindably on said carrier; a pair of free end position adjusting rollers mounted on said carrier for holding the tape unwound from the roll between them for hanging the tape in front of said application roller in the advancing direction of said carrier and adjusting a free end position of the tape; and drive means mounted on said carrier and operated by an operator for rotating one of said free end position adjusting rollers independently from rotation of said application roller and selectively in forward or reverse direction during adjusting of the free end position of the tape.
Claim 2
Dependent Claim
142 words
A pavement-marking tape applicator comprising: a carrier having at least one wheel and an application roller for engaging a pavement-marking tape and applying the same on a paved surface while rolling on the paved surface; means for supporting a roll of the pavement-marking tape unwindably on said carrier; a pair of free end position adjusting rollers mounted on said carrier for holding the tape unwound from the roll between them for hanging the tape in front of said application roller in the advancing direction of said carrier and adjusting a free end position of the tape; and drive means mounted on said carrier and operated by an operator for rotating one of said free end position adjusting rollers independently from rotation of said application roller and selectively in forward or reverse direction during adjusting of the free end position of the tape.
