ABSTRACT:
A method of conditioning a fiberboard mat having upper and lower surfaces for molding it into a three dimensional object by making a first series of internally directed discontinuous incisions in the fiberboard mat upper and lower surfaces; making a second series of internally directed discontinuous incisions in areas of the fiber board mat upper and lower surfaces which contain the first series of incisions; and, desirably, with incisions of the second series being angled with respect to incisions of the first series.
