Drywall tape
First Claim
1. A fire wall comprising:
- a) a supportive substructure;
b) a first sheet of drywall fastened to the supportive substructure;
b) a second sheet of drywall fastened to the supportive substructure adjacent to the first sheet to define a seam therebetween; and
c) a strip of drywall tape affixed to the first sheet and the second sheet to bridge the seam, wherein the drywall tape has a pressure-sensitive adhesive which joins a first paper layer to the drywall sheets and an adhesive joins a second layer of paper to the first layer of paper with a reinforcing layer therebetween, and wherein the second layer of paper has a release layer thereon.

Abstract
To assist in rapid taping of seams between adjacent drywall units, a tape is provided in rolls. The tape has a first layer of flexible paper material with an inwardly facing pressure-sensitive adhesive coating thereon. A second layer of reinforcing woven fiber material overlies the first layer. A third layer of flexible material overlies the woven fiber material to encapsulate the fiber material between the first layer and the second layer. The third layer has an outwardly facing release coating such that the first layer adhesive will releasably engage the third layer for manual separation of the tape when rolled upon itself. The adhesive is formulated to maintain adhesion even when wetted by an overlying layer of drywall mud. Furthermore, the release coating on the third layer accepts and allows the adherence of drywall mud. The tape may be used in fire wall applications. Perforations may be provided in the tape to facilitate adhesion.

4. A wallboard assembly comprising:
-
a) a first sheet of drywall; b) a second sheet of drywall positioned adjacent to the first sheet to define a seam therebetween; c) a strip of drywall tape affixed to the first sheet and the second sheet to bridge the seam, wherein the drywall tape has a pressure-sensitive adhesive which joins a first paper layer to the drywall sheets and an adhesive joins a second layer of paper to the first layer of paper with a reinforcing web of fiber strands therebetween, wherein portions of the strip define a plurality of perforations which extend through the drywall tape; and d) a coating of mud which extends over the strip of drywall tape and extends through the perforations to contact the first sheet of drywall and the second sheet of drywall.

5. A wall comprising:
-
a) a supportive substructure; b) a first sheet of drywall fastened to the supportive substructure; c) a second sheet of drywall fastened to the supportive substructure and positioned adjacent to the first sheet to define a seam therebetween; and d) a means for bridging the seam between the first sheet of drywall and the second sheet of drywall, wherein the seam bridging means has a means for adhering to the first sheet and the second sheet in response to the application of pressure, and a paper layer is connected to the means for adhering, and a means for releasing an adhesively attached tape is connected to the first paper layer and a means for reinforcing the tape is positioned between the means for adhering and the means for releasing.
