1. A joint tape for drywall, comprising:
- a substrate layer having an elongate shape in a lengthwise direction, the substrate layer being flexible in the lengthwise and in a transverse directions; and
a covering layer disposed in bonding relation on the substrate layer, the covering layer being 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 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.

10. A drywall joint between two adjacent drywall panels, comprising:
-
a layer of joint compound disposed along generally abutting edges of the two adjacent drywall panels; a joint tape embedded within the layer of joint compound, the joint tape comprising; a substrate layer having an elongate shape in a lengthwise direction along the generally abutting edges, the substrate layer being flexible in the lengthwise direction and in a transverse direction, which is perpendicular to the lengthwise direction; and a covering layer disposed in bonding relation on the substrate layer, the covering layer being rigid in the transverse direction and configured to withstand compressive forces applied generally in the transverse direction tending to push the two adjacent drywall panels towards each other, and shear stresses applied generally along the transverse direction tending to slide the two drywall panels relative to one another along the abutting edges thereof. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for manufacturing joint tape for use in drywall joints, comprising:
-
providing a substrate layer that is flexible in a lengthwise direction and in a transverse direction; providing a covering layer that is flexible in the lengthwise direction but is rigid in the transverse direction; depositing the substrate and covering layers in overlapping relation to create a joint tape preform; and bonding the substrate layer to the covering layer in the joint tape preform to create a joint tape that is flexible in the lengthwise direction but rigid in the transverse direction. - View Dependent Claims (20)
