Drywall tape, method of making and method of using the same

Abstract

A tape includes a paper substrate, and a coating of resin-remoistening adhesive on one surface of the paper substrate. The paper substrate defines a plurality of holes or interstices patterned longitudinally in a single line along or near a center line of the paper substrate. The tape is used for taping gaps, seams or joints between wallboard or drywall members, for example, for sealing a dry wall joint. Methods of making the tape and using the tape are also provided.

What is claimed is: 
     
         1 . A tape for sealing a dry wall joint, comprising:
 a paper substrate; and   a coating of resin-remoistening adhesive on one surface of the paper substrate;   wherein the paper substrate defines a plurality of holes or interstices patterned longitudinally in a single line along or near a center line of the paper substrate.   
     
     
         2 . The tape of  claim 1 , wherein the plurality of holes or interstices are spaced evenly apart along the centerline of the paper substrate. 
     
     
         3 . The tape of  claim 1 , wherein each of the plurality of holes or interstices is in a shape being round, oval, oblong or any combination thereof. 
     
     
         4 . The tape of  claim 1 , wherein each of the plurality of holes or interstices has a diameter or length in the range of from 3.175 mm to 22.225 mm. 
     
     
         5 . The tape of  claim 1 , wherein the plurality of holes or interstices are spaced by about 6.35 mm or about 3.175 mm. 
     
     
         6 . The tape of  claim 1 , wherein the plurality of holes or interstices are spaced by 3.175 mm while a space of 6.35 mm in length is interposed between two holes or interstices in every 20.32 cm of the tape in length. 
     
     
         7 . The tape of  claim 1 , wherein the paper substrate has a base weight in the range from 2.44 Kg/m 2  to 3.25 Kg/m 2 . 
     
     
         8 . The tape of  claim 1 , wherein the paper substrate has a dry tensile strength of at least 9.5 Kg of force per centimeter in a longitudinal direction, and at least 4.5 Kg of force per centimeter in a cross direction. 
     
     
         9 . The tape of  claim 1 , wherein the paper substrate has a width of about 2.54 cm. 
     
     
         10 . The tape of  claim 1 , wherein the coating of resin-remoistening adhesive is activatable with water or a wetting gel. 
     
     
         11 . The tape of  claim 1 , further comprising a longitudinal line of crease along the centerline of the tape. 
     
     
         12 . A tape product, comprising:
 a core; and   a tape for sealing a dry wall joint wound in a roll around the core, the tape comprising:
 a paper substrate; and 
 a coating of resin-remoistening adhesive on one surface of the paper substrate; 
 wherein the paper substrate defines a plurality of holes or interstices patterned longitudinally in a single line along or near a center line of the paper substrate. 
   
     
     
         13 . The tape product of  claim 12 , wherein the tape has a length in the range of from 7.62 m to 152.4 m, and the core has a diameter in the range from 6.35 cm to 7.62 cm. 
     
     
         14 . The tape product of  claim 12 , wherein each of the plurality of holes or interstices in the tape has a diameter or length in the range of from 3.175 mm to 22.225 mm. 
     
     
         15 . The tape product of  claim 12 , wherein the paper substrate has a width of about 2.54 cm, and the plurality of holes or interstices in the tape are spaced by about 6.35 mm or about 3.175 mm. 
     
     
         16 . The tape product of  claim 12 , wherein the coating of resin-remoistening adhesive is activatable with water or a wetting gel. 
     
     
         17 . A method of using the tape of  claim 1 , comprising:
 moistening the coating of resin-remoistening adhesive on one side of the tape;   applying the tape to a joint between two drywall panels, wherein the one side of tape with the coating of resin-remoistening adhesive faces the two drywall panels, and the plurality of holes or interstices are aligned longitudinally along about the center line of the joint; and   applying a joint compound for a first time, wherein the joint compound enters into the joint through the plurality of holes or interstices.   
     
     
         18 . The method of  claim 17 , further comprising:
 drying the joint compound after applying a joint compound for a first time.   
     
     
         19 . The method of  claim 17 , further comprising:
 applying the joint compound for a second time.   
     
     
         20 . The method of  claim 17 , wherein the coating is moistened and the tape is applied using a machine.
