Abstract: There is disclosed a strip applicator for dispensing and applying a strip from a roll thereof for covering joints or the like in wallboard or ceiling boards. The applicator has a main frame, a spaced-apart upper handle member and a spaced-apart lower roll mounting member, each being positioned in a spaced-apart planar relationship. The frame has first means for mounting the handle member in a first plane displaced from the frame member, and second means for mounting the roll mounting member in a plane displaced from and opposite to the plane of the handle member. Strip guiding means are mounted by the frame in operative relationship to the second mounting means, the strip guiding means are adapted to receive a strip from a roll thereof mounted on the lower roll mounting member and to guide the strip from the lower roll mounting member to and past the frame member whereafter the strip is adapted to be placed into juxtaposition with a joint between adjacent boards by the applicator roller.
