ABSTRACT:
A portable perimeter pressure sealer for sealing pressure sensitive adhesive strips along perimeter edges of a business form includes two pair of sealer wheels, the upper wheel of each pair being angularly movable relative to the lower wheel of each pair to insure uniform application of sealing pressure to a form passing therebetween. The upper wheels have peripheral pressure sealing surfaces which are biased into non-parallel relationship when no form is present between the respective sealer wheel pairs, but which are forced into a parallel relationship upon introduction of a form between the nips of the respective roll pairs.
