ABSTRACT:
A fibrous ply forming apparatus unit or module, which can be assembled with at least one additional essentially identical fibrous ply forming apparatus to form a multiply paperboard making machine, comprising four horizontally positioned spaced-apart rolls equally spaced from a vertical plane normal to the axes of the rolls, with said rolls being a tail roll, head roll, foot roll and guide roll, parallel to each other, a fibrous ply forming endless fabric belt wound over the four rolls, a low-vacuum box beneath a run of the fabric belt extending from the tail roll to the head roll for dewatering a forming fibrous ply deposited on said fabric run, and a high-vacuum box behind a run of the fabric belt extending from the head roll to the foot roll.
A method of manufacturing multiply paperboard by consecutively forming a series of separate paper plies on individual moving fabrics, mating second formed paper ply to one side of a first formed paper ply, mating a third formed paper ply to the other side of the first formed paper ply, sequentially mating any additional consecutively formed paper plies first to the second ply and then to the third ply and continuing such alternating side mating of any additional plies to be deposited, and as the second and each subsequent ply is mated to the board being manufactured, causing water in the newly added ply to flow from it to and out of the one or more plies constituting the partially formed paperboard.
