ABSTRACT:
The invention relates to an improved method and apparatus for producing paper board structures wherein two corrugated mediums are bonded together at their flute tips. End gears (16a, 16b, 15a, 15b) are provided, at least, on the ends of the corrugating rolls (4,6), which are non-meshing with each other and which assist in aligning the corrugated mediums in tip to tip arrangement and provide precise tip to tip bonding of the mediums. The end gears may be abutting or non abutting and may be provided on both ends of the corrugating rolls, which assist in aligning the mediums to obtain precise tip to tip bonding.
