A set of sheets delivered seriatim from a copier/duplicator or other source are advanced along a sheet path leading from an input station to an assembly station where a booklet is formed. As a sheet is moved along the path a line of adhesive is applied to one surface of the sheet adjacent to one side edge of the sheet. In the assembly station the sheets are jogged to align the sheets of the set and then pressure is applied to the sheets over the line of adhesive. When the entire set has been bound together into a booklet, the booklet is removed from the assembly station and delivered to an output station, such as a tote tray.

A nozzle for applying an air-curable adhesive to sheets of paper normally is located in a storage position with the end of the nozzle inserted into a liquid in a sump. This prevents adhesive material in the end of the nozzle from drying out or caking and thereby clogging the end of the nozzle. When the nozzle is to be used for applying adhesive, the nozzle is lifted out of the sump, the sump is moved, and the nozzle is then moved into an operating position for applying the adhesive. Also disclosed is apparatus for automatically returning the nozzle to its storage position with the end of the nozzle in the sump at the end of a cycle of operation, or when normal operation stops because of a power failure, for example.

An adhesive applicator for applying an air-curable adhesive to sheets of paper has a nozzle that normally is located in a storage position with the end of the nozzle inserted into a liquid in a sump. This prevents adhesive material in the end of the nozzle from drying out or caking and thereby clogging the end of the nozzle. When the nozzle is to be used for applying adhesive, the nozzle is lifted out of the sump, the sump is pivoted away from the nozzle, and the nozzle is then moved into an operating position for applying the adhesive.

A journal for forming the axle of a wick roller wherein the mounting section of the journal is provided with a nose section so that any adhesive which is skived from the core of the roller as the journal is positioned therein will collect on the nose section and will not foul the central bore through the core.

An adhesive applicator has a nozzle through which adhesive can be dispensed to sheets of a set as the sheets are driven seriatim past the nozzle. Adhesive is furnished in a cartridge which is pressurized so that the adhesive is delivered from the cartridge to the nozzle under pressure. A valve controls the flow of adhesive from the nozzle, and the valve is under control of a logic and control unit. The logic and control unit receives signals from various sensors or detectors indicating, inter alia, the presence of an adhesive cartridge, the level of adhesive in the cartridge, the flow of adhesive from the nozzle, and the amount of adhesive in a collection bottle which receives surplus adhesive dispensed from the nozzle but not applied onto a sheet. The logic and control unit is capable of operating the valve that controls flow of adhesive from the nozzle so that adhesive is selectively dispensed from the nozzle to all but one sheet of a set of sheets. A purge cycle is initiated if adhesive does not flow from the nozzle when commanded to flow by the logic and control unit.

A skive plate assembly for aiding receiver sheet removal from a roller in a fuser in an electrographic process, comprises a base plate, a skive plate having a central portion, and a skive plate attachment rigidly connecting the skive plate to the base plate such that the base plate and the skive plate define an air passage slot intermittently interrupted by the skive plate attachment, the skive plate defining a terminal edge positioned to face the roller, wherein a distance between the terminal edge and the base plate decreases with distance from the skive plate central portion. According to a further aspect of the invention, the terminal edge defines a gap with the roller, wherein the gap between the terminal edge and the roller is constant along the length of the skive plate.

A mechanism for applying pressure load force in a reproduction apparatus fuser device having at least one heated fuser member and a pressure member in nip relation to permanently fix a marking particle image to a receiver member. The pressure load force applying mechanism includes a load arm assembly rotatable about a fixed pivot axis to apply a pressure force to the pressure member, and a load cam selectively rotated about a drive shaft. A cam follower member is associated with the load cam, wherein a force of the load cam is applied via the cam follower member to the load arm assembly. A spring nest is formed as a part of the load arm assembly. The spring nest supports at least a heavy spring and a light spring; wherein the cam follower member, upon movement under the influence of the load cam, compresses the nested light spring and the heavy spring at different travel positions of the cam follower for varying the pressure force on the pressure member.

A transfer apparatus includes a transfer member, for example, a transfer drum with a line of small closely spaced laser drilled vacuum holes to hold a receiving sheet to the drum surface. The transfer drum is formed by forming a layer of at least intermediate conductivity material on the surface of a core, forming at least one vacuum opening in the core and laser drilling in the layer a line of closely spaced small holes communicating with the opening. In one embodiment, a short focal length lens focuses a laser beam near the surface of the layer, which beam spreads below the surface to form a conical hole. The conical hole helps maintain the continuity of a transfer field while being free from clogging.

Color toner images are transferred in registry to a receiving sheet held on a transfer drum. To facilitate releasing the sheet with the last image the drum surface is roughened, providing at least 0.002 inches between peaks and valleys. To offset difficulties created by such roughening in initial securing of the sheet to the drum, a transfer field is not applied as the leading edge of the sheet leaves the nip. The transfer field is applied after a short portion of the sheet, for example, 0.25 inches has left the nip.
