Abstract
A tool for finishing joints in wall board employs a generally cylindrical roller for applying pressure to imbed the tape in adhesive supported on a handle for applying pressure to the roller by a yoke rotatably supporting the roller in spaced locations along the roller axis. An adhesive trowel member is also supported on the yoke and provides an opening through which the roller projects. The trowel is positioned generally tangent to but slightly below the roller surface so that the trowel presents a curved surface of much greater radius than the roller and acts to redistribute the adhesive. A box scrapper also supported from the yoke about an axis parallel to the roller axis has a base and sidewalls, except on that side adjacent the roller. That particular side is left open to accumulate adhesive scrapped off the wall. The sidewalls are made to terminate in a common plane permitting flat contact with the wall and together act as a scrapper to collect adhesive in the box. A separate scrapper actuating means adjacent to the handle is connected to the box scrapper and enables the scrapper to be manually moved into place against the wall trailing the roller as the roller moves along a joint.
