ABSTRACT:
A method and apparatus for pinch perforating multi-ply web material to increase the perforation ply bond and/or perforation ply bond retention by pinching the multiple plies of web material together and then perforating the material using an anvil and perforator blade design provided on a perforating apparatus. Specifically, the apparatus comprises a roll mounted contoured perforator blade which cooperates with a beveled anvil to produce perforation ply bonds perpendicular to the length of the multiple plies of web material. The desired anvil/perforator blade interface angle between 0.degree. and 20.degree. is provided by beveling the anvil. A 15.degree. beveled anvil is preferred to provide a 5.degree. anvil/perforator blade interface angle. By pinching and bonding the leading edges and other predetermined points of the multi-ply tissue paper together before cutting, the likelihood of ply separation, missing plies and ply mismatch is greatly reduced.
