Abstract: A pressure sealer machine is provided for the production of pressure sealed documents, and more specifically nested documents, that uses a number of roller cassettes disposed in side-by-side relation, in parallel to at least one drive roller, for handling forms with inserts. In the preferred embodiment, each cassette is a dual roller cassette to include infeed and outfeed rollers. The cassettes are sized relative to the wheels so that there is a lateral gap between adjacent seal wheels, so that the cassettes produce a seal pattern composed of a series of seal strips having a uniform gap therebetween. Each cassette is spring loaded at its top side and pressure is uniformly applied to the system using a pressure plate to compress all cassette springs simultaneously.

Abstract: A simplified pressure sealing apparatus for acting on business forms having pressure activated cohesive to seal the cohesive has only two or three pressure-seal rollers for effecting proper sealing. The pressure seal rollers may receive a folded business form substantially immediately from the output of a folder, or one of the pressure-seal rollers may function to both assist in folding the form, and then pressure sealing it. The form may be held in a flip plate above the nip between first and second pressure-seal rollers, or a separate set of idler nip wheels may hold the form in position once it has passed completely through the sealing nip. In either case the form may pass completely through the sealing nip yet be moved through the sealing nip in the opposite direction, and then diverted to a stack.

Abstract: A vertical pressure sealing assembly is disclosed for sealing four edges of a business form. The assembly defines a business form path in a single vertical plane. The assembly includes two sealing modules each having a frame to support upper and lower sealing wheels. The sealing wheels are aligned with the outer edges of the business form. Each sealing module includes a first and second pair of upper/lower sealing wheels on each side of the module frame. The first frame is positioned vertically above and offset from the second sealing module. The second sealing module is orthogonal to the first module. A form chute between the two sealing modules is positioned immediately below the first sealing module and adjacent the second sealing module. Conveyor belts and drive wheels are used to move the business form through the vertical pressure sealing assembly.

Abstract: A bi-directional stacking conveyor is mounted below the discharge from a main conveyor and lies substantially perpendicular to the main conveyor. An adjustable length backstop and adjustable width guide fingers are carried by the stacking conveyor to accommodate forms of different lengths and widths, the backstop and side guides holding the sheets snugly in the stack. In response to a signal from a controller, the guide fingers on a side of the stack in the direction of desired movement are displaced to an out-of-the-way position and a motor drives the stacking conveyor belt to displace the stack in a first direction.

Abstract: Specialized sheets, for example, in the construction of business forms, having patterns of pressure activated cohesive are constructed so that all the sheets can be identical yet when the sheets are in a stack blocking of the pressure activated cohesive, and subsequent feeding problems, are eliminated by making the cohesive patterns offset a dimension "d" perpendicular to the direction of feed of the forms from a feed bin through an imaging device to an output tray. Either the feed bin, or an edge guide of the output tray, can be shifted at least the dimension "d" to automatically align the pressure activated cohesive patterns on cooperating first and second sheets, and after proper alignment of the cohesive patterns the sheets may be fed through a conventional pressure sealer.

Abstract: A high capacity conveyor assembly is utilizable with pressure sealers or other business forms manufacturing or handling equipment to efficiently handle forms that may be job separated, and provides high capacity outfeed. An infeed conveyor has a first horizontal conveyance surface and feeds forms in a first direction to a pair of nip wheels, with an outfeed conveyor downstream of the wheels for also feeding forms in the first direction and having a second horizontal conveyance surface. The nip wheels are powered and include a top nip wheel and a bottom nip wheel with a nip between them, the bottom nip wheel having a top peripheral surface closer to the outfeed conveyor than is the nip. A transition element (such as a low friction shelf) has a form supporting surface lower than the bottom nip wheel top peripheral surface, and is between the nip wheels and outfeed conveyor.

Abstract: Business forms may be manually inserted into cooperation with a conveyor between a folder and a sealer by providing an outer movable cover for the conveyor, and an inner normally stationary cover underneath the outer cover. An interlock, formed by a magnet and a reed switch, is provided between the inner cover and the conveyor. A slot is formed in the inner cover, with first and second guide elements extending upwardly and downwardly, respectively, from the slot. Each of the guide elements has a plate, the first guide element having one upstanding guide edge, and the second guide element having adjustably spaced first and second S-shaped guide edges. A planar transition portion of the first guide element overlaps and is connected to the second guide element, and a planar transition portion of the second guide element is connected to the bottom of the inner cover. The second guide element plate makes an angle of between about 30.degree.-60.degree.

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.
