Abstract
An improved drywall tape is comprised of an elongated ribbon of porous paper tranversely corrugated throughout its length and having a fexible, elongated plastic bead secured to the ribbon of paper and extending longitudinally along the length of the paper. The plastic bead provides a distinct, protected corner to finished drywall, and the corrugations in the tape strengthen the tape to make it stiffer and harder when it dries and easier to work with during installation.
Claims2
