CORRUGATED FIBRE BOARD
Corrugated paper board
3 ply (40" x 60" size) -
16,38,000 Boards per annum
Two paper reels are run together on corrugating machine. One layer of paper becomes corrugated after passing through the heated fluted rolls and the other is brought in contact with the former having been glued at the tips. These two get pasted together and are wound in rolls. The resulting roll is now known as single face or 2-ply corrugated paper. By cutting this roll with board cutter and glueing the corrugated side on pasting machine, double face or 3rd ply corrugated boards is produced by placing the 3rd ply of paper over it. This board is kept under a sheet- pressing machine for some time for setting of the wet glued sheets. Similarly, board to board can be pasted to form thicker board i.e., 5 ply, 7-ply and 9-ply, etc.
