Abstract
Abstract A drywall joint filler for joining together two conventional drywall building panels formed as an extending flexible strip of plastic or the like having a central spline which extends into the space between the panels to properly locate the joint and which tapers to a feather edge as it extends away from the spline. The spline is preferably provided with whiskers or spurs to provide additional holding forces. The joint is preferably adhered to the abutting panels by double-coated adhesive paper strips.
