Abstract

Abstract A device which applies a strip of masking tape to a pipe, particulary to the inside pipe surface. A frame carries a pair of rollers which roll along the inside pipe surface. The tape is mounted on a reel and is unwound in a strip which is pressed against the inside pipe surface by the rollers. An outer guide roller is carried on a hand lever assembly and is biased against the outside surface of the pipe in order to maintain the inner rollers against the inside pipe surface. The hand lever may be pulled away from the pipe to disengage the outer roller therefrom for removal of the applicator device from the pipe.
