Abstract
A masking device including a substantially rigid body, the body having an underside and adjoining first and second edges and an L-shaped adhesive portion positioned on the underside adjacent to one or more of the first and second edges and methods for making, using and removing the masking device to mask corners of flat surfaces such as windowpanes, walls, ceilings and floors.
Claims23
A masking device comprising:
- a substantially rigid body, said body having an adhesive underside and adjoining first and second edges;
- and
- a thin sheet positioned on said underside, said thin sheet including a separable L-shaped portion positioned along said first and second edges.
A deck of masking devices comprising:
- a plurality of stacked, releasably attached masking devices, wherein each of said plurality of stacked masking devices comprises a substantially rigid body, said body having an adhesive underside and adjoining first and second edges;
- and
- a thin sheet positioned on said underside, said thin sheet including a separable L-shaped portion positioned along said first and second edges.
A method of manufacturing masking cards comprising:
- coating an underside of a card with an adhesive;
- coating a top side of a thin sheet with a release agent in an L-shaped pattern;
- laminating the underside of the card to the top side of the thin sheet;
- forming a line of separation in the thin sheet along the L-shaped pattern;
- applying a pattern of tipping glue to a top of the card;
- and
- forming a plurality of the cards into a deck.
A method of masking a flat windowpane with a masking device, the window including a frame and at least one flat windowpane positioned within the frame, the windowpane having a plurality of corners comprising:
- a) removing a masking device from a deck of masking devices;
- b) removing an L-shaped portion of a thin sheet from an underside of the masking device;
- c) exposing an L-shaped adhesive pattern on the underside of the masking device;
- d) adhering the masking device underside of the masking device into one of the plurality of windowpane corners such that the L-shaped adhesive pattern is positioned in the corner;
- e) repeating steps a-d until all of the plurality of corners are masked by a masking device with gaps between each adjacent pair of masking devices;
- and
- f) applying masking tape to span the gaps such that an outside edge of the windowpane is completely masked.
A method of manufacturing masking cards comprising:
- providing a master sheet of a masking device body material;
- applying an adhesive material in a predetermined pattern to an underside of the master sheet;
- and
- subdividing the master sheet into a plurality of individual masking devices wherein the predetermine pattern provides a strip of adhesive material along two adjacent edges of each of the plurality of individual masking devices.
