Abstract
Abstract The invention is for an applicator, such as a glue applicator, which is adapted to place a line or bead of adhesive or the like against a workpiece. There are adjustment means to vary the application height of the line of bead. The adjustment means comprise an adjustable extension bearing in the form of the screw and a screw-receiving portion so that when the screw is screwed into the screw-receiving portion to different depth there will be a corresponding adjustment of the portion of the line of bead of adhesive as applied.
