Masking device hub providing two position tape support

A portable device for use with a roll of masking material comprising a length of masking material helically wound around a masking material core and having opposite major surfaces and opposite first and second elongate edges, and a roll of tape comprising a length of tape helically wound around a tape core having a cylindrical inner surface, said tape comprising a backing having front and rear surfaces and opposite first and second elongate edges and a coating of pressure sensitive adhesive on said front surface, said portable device comprising:

• a frame including a handle adapted for manual engagement to manipulate said device;
• tape and masking material hubs mounted on said frame for rotation about spaced generally parallel axes, said tape hub including means for receiving the core of said roll of tape and for positioning the first edge of the length of tape at a predetermined tape edge position axially with respect to said first and second hubs, and said masking material hub including means for receiving the core of said roll of masking material and positioning the first edge of the length of masking material at a predetermined masking material edge position axially with respect to said tape and masking material hubs with the, width of said length of tape extending from the tape edge position past the masking material edge position and the width of the masking material extending from the masking material edge position past the tape edge position so that a portion of the length of tape along the first edge of the length of tape and a portion of the length of masking material along the first edge of the length of masking material are both positioned between said tape edge and masking material edge positions;
• and
• path defining means defining a path for said length of tape from said roll of tape and a path for said length of masking material from said roll of masking material, said paths including a tape path portion for said tape from said roll of tape to the peripheral surface of said roll of masking material and a common path portion beginning at the peripheral surface of said roll of masking material where said portion of the length of tape along the first edge of the length of tape is adhered to said portion of the length of masking material along the first edge of the length of masking material to form a composite masking sheet having opposite edges defined by the second edges of the length of tape and the length of masking material and an exposed portion of the coating of pressure sensitive adhesive along the second edge of the length of tape along one major surface of the composite masking sheet so that the exposed portion of coating of adhesive can be adhered along a surface to be masked to attach the composite masking sheet thereto;
• wherein said tape hub includes means for alternately locating the first edge of the length of tape at either of two different discrete tape edge positions to thereby afford changing the width axially of said hubs of the portion of the length of tape along the first edge of the length of tape and the portion of the length of masking material along the first edge of the length of masking material that are positioned between said tape edge and masking material edge positions.
