ABSTRACT:
A joint-taping tool for wallboard (drywall), wherein there is almost no possibility that the cable will break after the piston reaches the top of its stroke, and wherein the operator is immediately and unquestionably informed when adhesive flow ceases. Furthermore, mechanism is provided by which--with minimized action on the part of the operator--the rollers are prevented from spinning and "throwing" adhesive (cement) during filling of the barrel.
The tool will not only apply tape and adhesive simultaneously, but is rapidly convertible to deposit adhesive over previously-applied tape. This same conversion spacing option makes it possible to eliminate tape jams quickly and easily. In addition, means are provided for thoroughly cleaning the tool at the end of each day.
