A system and method for pressure sealin, business forms provide for maximum utilization of floor space and ease of control by an operator. First and second pressure sealing devices (11, 12), each having upper and lower sets of rollers (18, 20; 18', 20') forming nips for sealing business forms (55) only along strips of pressure sensitive adhesive, are mounted one above the other. A common drive (28) is provided for the drive rollers of each set, for each sealing device. Tape conveyors (37, 44, 49) assist in conveying the forms through the first sealer, around a horizontal axis large diameter drum (42), and from the large diameter drum through a second sealer, the forms moving in the opposite direction to the one they moved in through the first sealer when going through the second sealer. A rotator (14) is provided between the drum and the second sealer for changing the orientation of the forms about 90<o>. The forms are fed to the first sealer by an infeed conveyor/deshingler (15), and are removed from the second sealer by an outfeed conveyor/stacker (16). <IMAGE> |
