ABSTRACT:
A tape is adhered to a corner-defining nonstraight edge of a generally planar workpiece with an apparatus comprising a stationary workpiece station, clamps for retaining the workpiece in the station, a roller engageable with the workpiece and rotatable on the carriage about an axis generally perpendicular to the workpiece plane, and a supply of the tape and an adhesive on the carriage. The roller and workpiece are relatively displaced to roll the roller around the workpiece edge and over the corner thereof while pressing the tape with the roller against the workpiece edge and corner. The tape feed is automatically monitored to determine which portion of the tape will be pressed over the edge corner and a notch is cut in the tape at the portion to be pressed to the corner. Then this notched portion of the tape is pressed over the corner without overlapping the tape.
