ABSTRACT:
In a corner roller tool for rolling mud laden applied tape into a corner dry wall seam, a pair of tandem rollers are provided for rolling the creased tape into the corner seam and for squeezing out excess mud from beneath the tape. The rollers each comprise a wheel having a tread portion of generally V-shaped radial cross section. The included angle .theta. between the opposed faces of the V-shaped tread portion is approximately 90.degree. for pressing the tape into firm engagement with the side walls of the corner seam. The corner roller wheels are carried from a frame which is pivotably coupled to a elongated handle. The handle is pivotable in at least two orthogonal directions to facilitate rolling of the tape into the corner seam when the operator can not face directly into the seam. The corner roller wheel are free to move laterally on their respective axles to facilitate tracking of imperfect seams. The included angle between the tread face portions of the two wheels are preferably larger than 90.degree. for one wheel and less than 90.degree. for the other to facilitate pressing of the tape into imperfect right angle corner seams.
