  • Method of preforming a one-piece wall covering
    Patent number: 4187273
    Abstract: A single sheet of standard grade plastic laminate material is bent at two locations to form it into a side wall and two end walls corresponding to the side wall and two end walls of a bathtub recess. Following forming, one end wall portion of the wall covering is loosely folded over the opposite end wall portion. Then, the partially folded wall covering is pushed endwise into a rectangular cardboard box having a normal thickness which is substantially smaller than the initial depth of the partially folded wall covering. The box with the partially folded wall covering inside is moved through a rectangular opening provided in a rigid mandril, sized to be substantially equal to the normal outside dimension of the box. The mandril forces the outwardly bulging side walls of the box inwardly and reshapes both the side walls of the box and the side and end walls of the partially folded wall covering therein.
