    Abstract: Cinta para juntas (200) para panel de yeso laminado, que comprende: una capa de sustrato (204) que presenta una forma alargada en una dirección longitudinal y un ancho estrecho en una dirección transversal para formar una banda, y una capa de recubrimiento (208) dispuesta en relación de unión sobre la capa de sustrato, caracterizada por que: la capa de sustrato está formada por fibras de sustrato (206), siendo flexible la capa de sustrato en la dirección longitudinal y también flexible en la dirección transversal que es perpendicular a la dirección longitudinal para permitir que la capa de sustrato se doble en las direcciones longitudinal y transversal; y la capa de recubrimiento está formada por fibras de recubrimiento (210), incluyendo las fibras de recubrimiento fibras con extensión transversal que se extienden en paralelo entre sí a lo largo de la dirección transversal, siendo las fibras con extensión transversal rígidas en la dirección transversal para resistir la flexión en la dirección transversal y estando configuradas para soportar fuerzas de compresión aplicadas generalmente en la dirección transversal y tensiones de corte aplicadas generalmente en la dirección transversal; donde la cinta para juntas es flexible en la dirección longitudinal, permitiendo de esta manera que la cinta para juntas se enrolle en un rollo (202), y rígida en la dirección transversal para soportar tensiones de compresión aplicadas en la dirección transversal.

    Abstract: A joint tape for drywall includes a substrate layer having an elongate shape in a lengthwise direction and being flexible in the lengthwise direction and in a transverse direction. The tape further includes a covering layer disposed in bonding relation on the substrate layer. The covering layer is rigid in the transverse direction and configured to withstand compressive forces applied generally in the transverse direction and shear stresses applied generally along the transverse direction.

    Abstract: A joint tape to be applied to wallboard is provided and includes a base substrate having opposing sides. In certain embodiments, a first adhesive layer is applied to one of the sides of the base substrate and a second adhesive layer is applied to the first adhesive layer, where the first adhesive layer is different than the second adhesive layer, in preferred embodiments the second adhesive being activatable by water. In certain other embodiments, two different adhesives are used in a single adhesive layer. In use, the joint tape is positioned over and removably secured to a joint or corner between adjacent wallboard panels using the first adhesive layer. After the joint tape is in position, joint compound is applied to the joint tape, and the water in the joint tape activates it to form a secure bond with the wallboard panels.

    Abstract: Corner beads finish a rough corner into a pleasing symmetrical transition with the respective adjoining walls, and also provide some resistance to abuse and impact on the corner. To accomplish these tasks, a suitable corner bead product should fit snugly on the wall, be easy to attach, and have material and design properties that allow it to resist at least minor impacts without severe damage or detachment from the wall. Conventional corner bead strips are either made of metal or various types of plastic, and are provided in relatively rigid lengths or in flexible rolls. Flexible corner bead strips are typically two types. In the first type, 2 metal strips approximately 0.010-0.015 inch (0.025-0.038 cm) thick are disposed parallel to each other, are laminated to a web of paper with a slight separation gap between the strips so that the strip may be flexed as desired to match the corner profile. The flex bead strips are then applied to the wall corner and secured using wallboard joint compound. Disadvantages of conventional flexible metal corner bead strips include that the metal is relatively heavy, expensive, is easily bent or kinked, and is often difficult to straighten completely when provided in rolled form. In addition, due to the gap between the adjacent strips, it is sometimes difficult to obtain a straight or plumb corner edge, and also the actual corner of the wall is only protected by paper, and as such is prone to impact damage. Conventional flexible plastic corner bead strips suffer from the same susceptibility to impact damage at the wall corner. A corner bead strip is provided for finishing a wallboard corner joint, includes a flexible plastic body having a first flange and a second flange, each flange with a corner edge and an opposite free edge. The corner edges are joined by a central flex zone formed by a plastic composition distinct from a plastic composition used for forming the flanges. A web of paper covers a surface of the body. The web of paper covers the outside surface of the corner bead strip, the opposite inside surface of said body being free of any paper covering. A corner bead strip for finishing a wallboard corner joint is provided, comprising: a flexible plastic body including a first flange and a second flange, each said flange having a corner edge and an opposite free edge, said corner edges being directly joined by a central flex zone encompassing a longitudinal axis of said strip, said flex zone being coextruded and formed by a second plastic composition in a region distinct from and more flexible than a first plastic composition in a distinct region used for forming said flanges said flex zone is made of said second plastic composition which is said first plastic composition combined with a flexibility modifier that is distinct from said first plastic composition, said first plastic composition directly contacting said wallboard corner joint, said first region provided with a “V”-shaped recess between said corner edges, said second region tapering toward each of said free edges, said flexible body being configured for being bendable about said axis to a 90-degree angle, and retaining said bent angle without relaxing back to an initial flat position; said first and second plastic compositions are taken from the group consisting of polystyrene, PVC, PET, and polycarbonate, and at least one of said compositions including said flexibility modifier; and a web of paper covering an outside surface of said body, the opposite inside surface of said body being free of said covering.

    Abstract: A formable trim strip (10) for use in connection with drywall applications, the formable trim strip comprising: a trim strip body extending along a body axis and having a top surface and a bottom surface, the trim strip body comprising a polymer material with a melting point range, preferably between about 250° F and about 400° F; and a backing paper, wherein a portion of the backing paper is secured to the bottom surface of the trim strip body without an intervening layer of adhesive material, and wherein the trim strip body is coated onto the portion of the backing paper when a temperature of the trim strip body is within the melting point range such that the bottom surface of the trim strip body contacts the portion of the backing paper, and as the trim strip body cools to a temperature below the melting point range, the portion of the backing paper bonds to the bottom surface of the trim strip body.
