ABSTRACT:
The machine of the invention comprises a pair of rolls on powered shafts with the ends of the rolls being fixed to the shafts and the central portions of the rolls floating on the shafts. When a mailing form piece and a wafer seal are moved in between the rolls, the powered roll ends engage only the form and pull it through the floating sleeves which sleeves are stopped from rotating when engaged by the seal to retard the movement of the seal and form a tight fit between the seal and the form.
