Abstract
A drywall finishing system where a continuously extruded, elongated semi-rigid member with an inner and outer layer of fibrous material has a groove running end-to-end allowing the piece to assume any angle to match a drywall seam. The groove is held at a fixed angle near 89 degrees (or any other fixed angle) by a break-apart bead running in the groove. The break-apart bead can be glue or extruded plastic or other means that holds the flanges at a rigid angle. If the seam is a right angle, the piece is used without breaking the bead. If the seam is any other angle, the break-apart bead is snapped or cut apart allowing the flanges to assume any angle.
Claims13
A separable flexible drywall trim piece comprising:
- a elongated semi-rigid member bonded to an inner layer of fibrous material and an outer layer of fibrous material, said outer layer receiving paint or texture directly, said semi-rigid member forming a left and a right flange;
- a groove running the length of said elongated semi-rigid member, said groove forming a hinge between said left flange and said right flange allowing said flanges to flex to any angle;
- a break-apart bead running the length of said groove, said bead holding the angle between said flanges fixed at a predetermined angle, said bead being broken by snapping said flanges apart allowing said flanges to assume any angle.
An apparatus for finishing drywall seams of the type where wet drywall mud is first placed on both sides of a seam and the apparatus is pushed into the wet mud, the mud holding the apparatus in place while the edges are feathered into the surrounding drywall with mud, the apparatus not receiving mud on a front surface, but rather receiving paint or texture directly on said front surface, said apparatus comprising, in combination:
- an elongated, continuously extruded semi-rigid support member with an inner and outer paper layer, the outer paper layer being prepared to directly receive paint or texture;
- a groove running end-to-end acting as a hinge allowing the apparatus to match any wall angle;
- a break-apart bead running end-to-end in said groove, said break-apart bead holding said apparatus at a fixed, manufactured angle of around 89 degrees;
- said break-apart bead being snapped apart if necessary so said apparatus matches angles other than a right angle.
A drywall finishing apparatus comprising:
- a continuously extruded elongated semi-rigid member with two flanges, each of said flanges having an inner and an outer layer of fibrous material;
- a groove running end-to-end along a centerline forming a hinge allowing said flanges to assume any angle;
- a means for holding said flanges at a rigid angle of around 89 degrees running end-to-end along said groove, said means for holding said flanges being snapped apart if necessary allowing said flanges to assume any angle.
