Abstract
A drywall sheet with a gypsum core sheathed in front and rear paper layers, an edge of the sheet being tapered towards the rear, the taper being formed by a flap of a marginal area of the front paper and a thin layer of gypsum attached to an inner side of the front paper margin being folded into a space resulting from a slot cut in the sheet edge to a depth generally equal to the width of the flap, the flap being held in place by a continuous layer of a hot melt adhesive occupying a space of the slot not occupied by the flap and having an elasticity that imparts fastener penetration resistance to the associated edge from a front face of the sheet.
