Abstract
A tape and masking material composite including a sheet of masking material, and a length of pressure sensitive adhesive coated tape adhered to a first surface along a first edge of the sheet of masking material with the tape having a longitudinal pressure sensitive adhesive covered portion extending past the first edge of the sheet of masking material. The masking material has removable pressure sensitive adhesive on a second major surface opposite its first major surface at least including on and along a portion of that second surface along a second edge opposite its first edge.
Claims21
A tape and masking material composite comprising an elongate sheet of masking material having opposite first and second major surfaces and first and second opposite edges between said major surfaces, and a length of pressure sensitive adhesive coated tape adhered to said first surface along said first edge of the sheet of masking material with the tape having a longitudinal pressure sensitive adhesive covered portion extending past said first edge of the sheet of masking material, said masking material having removable pressure sensitive adhesive on said second surface at least including on a portion of said second surface along said second edge.
A combination for use to mask a surface, said combination comprising:
- a roll of material having an axis and first and second axially spaced ends, said roll of material comprising:
- a stiff cylindrical core having an inner surface defining a through opening, and having a cylindrical outer surface;
- an elongate thin sheet of flexible conformable masking material having opposite first and second major surfaces, and first and second opposite elongate edges, said masking material restricting absorption of liquids applied to said first major surface;
- and
- removable pressure sensitive adhesive on said second major surface of said sheet of masking material at least including on portions of said second surface along said first and second edges,
- said masking material being helically coiled about an outer surface of the core with the layer of adhesive adjacent the core;
- and
- a portable dispensing apparatus comprising:
- a frame including a portion of the frame adapted for manual engagement:
- means on said frame receiving said roll of masking material for rotation about the axis of the roll relative to the frame;
- and
- path defining means on said frame defining a path for said masking material being pulled from the dispensing apparatus;
- and
- a cut off blade mounted on the frame, extending generally parallel to the axis of the hub, and defining a first side of said path, said cut off blade being adapted to transversely sever the masking material when the masking material is tensioned around a cutting edge on the blade as the masking material is being pulled away from the dispenser.
A combination of:
- a roll of masking material having an axis and first and second axially spaced ends, said roll of masking material comprising:
- a stiff cylindrical core having a through opening, and a cylindrical outer surface;
- the elongate, thin, flexible, conformable masking material having opposite first and second major surfaces and opposite longitudinally extending first and second opposite edges, said masking material restricting absorption of liquids applied to said first major surface, and
- a coating of removable pressure sensitive adhesive on said second major surface of the sheet of masking material at least including on a portion of said second surface along said second edge,
- said masking material being helically coiled about an outer surface of the core with the layer of removable adhesive adjacent the core;
- a roll of pressure sensitive adhesive coated tape having longitudinally extending first and second opposite edges;
- and
- a portable dispensing apparatus comprising:
- a frame;
- a handle mounted on the frame adapted for manual engagement:
- first and second hubs mounted on said frame for rotation about spaced generally parallel axes, said first hub receiving the roll of tape and positioning a first edge of a length of the tape withdrawn from the roll at a first predetermined position axially with respect to the first and second hubs, the second hub receiving the roll of masking material and positioning a first end of the roll of masking material at a second predetermined position axially with respect to the first and second hubs with the width of the length of tape extending from the first position past the second position and the roll of masking material extending from the second position past the first position, 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 end of the roll of material both being positioned between said first and second positions, said dispenser including means defining a path for the length of tape from the roll of tape to the periphery of the roll of masking material where the portion of tape along the first edge of the length of tape is adhered to the portion of the masking material along the first end of the roll of masking material, such adhesion of the tape to the masking material along the periphery of the roll of making material forming a tape and masking material composite 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 on the length of tape along one major surface of the tape and masking material composite so that the exposed portion of the coating of adhesive can be adhered along a surface to be masked to hold the tape and masking material composite in a desired position;
- path defining means on said frame defining a path for said tape and masking material composite being pulled from the dispensing apparatus;
- and
- a cut off blade mounted on the frame, extending generally parallel to the axis of the hub, and defining a first side of said path, said cut off blade being adapted to transversely sever the tape and masking material composite when the tape and masking material composite is tensioned around a cutting edge on the blade as the tape and masking material composite is pulled away from the dispenser.
