Abstract: An edge blending masking tape dispenser has an upright support plate and a base with a tear off edge above the base. A roll of adhesive coated masking tape is journaled and yieldably retained upon the support plate and passes over a tape edge folding and forming die which has a cam surface so as to constrict and upwardly deflect and form the leading one edge portion of the tape. The tape further passes over and around the tape support in tension with the upwardly deflected one edge of the tape folded down upon the adhesive side thereof. This provides a non-stick free floating edge along the tape to permit feathering and blending of new paint with an existing tape finish, when the masking tape is adhered thereto.

Abstract: In a deburring apparatus having a housing with front and rear walls, a base and a power rotated deburring wheel within the housing and partly projecting through the front wall, a workpiece holder assembly is arranged forwardly of the front wall in registry with the deburring wheel. The workpiece holder assembly has an elongated feed tube guidably mounted upon the base. A feed screw assembly interconnects the base with the feed tube and is actuated from the rear of the housing. Vertical feed tube is coplanar with and at substantial right angles to the elongated feed tube and upon one end is secured thereto. A workpiece holder shaft is telescoped within the vertical feed tube and mounts a transverse workpiece support. A feed screw assembly interconnects the vertical feed tube and workpiece holder shaft and is adapted on actuation to raise and lower the workpiece holder shaft and connected workpiece support.
