Abstract
Described herein is a system and method to produce a taper on a drywall board to facilitate taping and compounding where two boards abut. A groove is formed on the back side of a drywall board, resulting in a first gypsum-containing segment hingeably connected to a second gypsum-containing segment. A taper is created by rotating the segments until they meet, and then removing excess material.
Claims22
A method of tapering an end of a drywall board, the method comprising:
- providing a drywall board having a back side with a framing drywall liner, a front side with a finishing drywall liner, and an edge;
- creating a groove on the back side of the drywall board parallel to the edge, wherein the groove a) has a void therein, b) has a depth that extends to but does not sever the finishing drywall liner, and c) gives rise to a hinge that includes the finishing drywall liner, said hinge connecting a first segment of the drywall board on one side of the groove to a second segment of the drywall board on another side of the groove, such that the second segment includes the edge;
- and
- closing the void in the groove by rotating at least one of the first segment and the second segment about the hinge.

A drywall board having a tapered end proximal to an edge of the board, comprising:
- a first gypsum-containing segment;
- a second gypsum-containing segment abutting the first segment at a boundary therebetween;
- a finishing liner integrally covering an area on a front side of the first segment and a front side of the second segment;
- and
- a seam located where the first segment and the second segment abut, said seam being parallel to the edge and on a back side of the first and second segments.
