ABSTRACT:
When manually propelled along a joint toward a barrier, as when manually propelled upward along a joint between wall panels this system covers the joint with heat-sealable metallic tape, heating the tape with an electric sole-plate, and by means of locking the tape-feed stops itself, preventing further propulsion, at exactly the right distance from the ceiling so that the tape when plunger-cut using a provision of the system will just extend to the ceiling and no more; cutting the tape releases the system so that it can be advanced by the ceiling to complete laying the terminal or cut end of the tape; this operation applies as well to traversing a ceiling joint or crack and laying tape right up to a wall; special collapsing sensor arm provisions and spool locking provisions co-act to produce the automatic measuring and tape laying; a graduated adjustment provides for calibration of the system.
