ABSTRACT:
A mounting arrangement is provided for rollers in a pressure sealer wherein a folded business form is fed along a processing path between at least one pair of cooperating, rotating, first and second rollers. A support structure is provided for holding the rollers with the first roller in a fixed location while accommodating movement of a second roller along a plane in either of two opposite directions toward and away from the first roller. Each roller has a pressure-applying, cylindrical surface. Each roller has two spaced-apart bearing structures for engaging the support structure to accommodate rotation of a respective one of the rollers and for engaging one of the bearing structures of the other rollers to define a predetermined minimum spacing between the cylindrical surfaces of the first and second rollers. At least one spring is provided for urging the bearing structures of the second roller toward the bearing structures of the first roller. At least one adjusting bar is pivotally mounted on the support structure for bearing a load imposed by the spring. A cam is provided for engaging the adjustment bar and urging the adjustment bar to compress the spring. An operating lever extends from the cam and can be pivoted to rotate the cam to effect a reduction or increase in the compression of the spring.
