Open the CIPO recordAbstract From the Canadian patent
A continuous form mailer set assembly is provided in which the interior plies of each mailer set are extended into both line hole stubs. The interior plies associated with each mailer set are completely separate one from another and there is no continuous stub on either side of the interior plies. Thus, only the two outside plies are glued together where the form is folded and this eliminates the tenting problem. Both sides of all of the interior plies have slots punched through them and the glue lines are put down so that when the form is assembled the glue bleeds through the corresponding holes of the interior plies to maintain their registration.
