ABSTRACT:
A pressure sealer for sealing pressure sensitive adhesive strips on business forms or the like is simple and straight forward, for use primarily in manual operations. First and second driven rollers convey business forms during sealing, and are driven by a single motor driven gear meshing with Delrin gears integral with the rollers. Pressure applying rollers are mounted above and in alignment with first and second rollers, and are biased by an adjustable spring mechanism to provide the necessary pressure to effect sealing. The spring force applying mechanism can also be disabled so that no force is applied to allow ready inspection and/or replacement of the components, by utilizing a particular procedure including replacing one bolt with a longer thinner bolt. Pinching of the operator's fingers is prevented by a flap disposed in association with a lead-in platform for the forms, just prior to the rollers. The second roller in the direction of form conveyance may a slightly larger diameter than the first roller to effect pull-up of a document feeding from the first roller to the second roller.
