ABSTRACT:
An apparatus for applying parallel spaced-apart creases on paper to be used as cover sheets in the manufacture of gypsum board, the parallel spaced-apart creases forming the corners of the wallboard and the distance between creases defining the thickness thereof, the apparatus being adjustable to control the depth of the creases applied so that substantially no paper material is removed during the creasing process, and the creases applied are of sufficient depth to permit sharp corners to be readily formed.
