  • Patent number: 8393608
    Abstract: A substrate finishing system includes a sheet input that feeds sheets to a compiler for compiling. The sheets may be stapled at the compiler. A trail edge support of the compiler is movable from a first position to a second position. The compiler is configured to drop a sheet or set of sheets to build compiled set stacks at the first and second positions on a stacking tray positioned beneath the compiler.
    Type: Grant

  • Publication number: 20120189969
    Abstract: A belt-roll fuser system includes a belt-roll fuser module that is movable to engage and disengage to a main frame of the belt-roll fuser system. The belt-roll fuser has an internal pressure member that defines a fusing nip with an external pressure member of the main frame when the belt-roll fuser module is engaged. The belt-roll fuser module is movable by a latch, and when engaged, a nip load path crosses through a point at which the latch attaches to the belt-roll fuser module.

  • Patent number: 7631868
    Abstract: A retractable scuffer includes an arm with foldaway drive wheels connected thereto that are independently pivotable to ensure even drive force on a sheet. The drive wheels flips down in a counter clockwise direction as the scuffer arm is driven to an extended position by a lead screw mechanism. This provides a shallow angle of contact with the sheet and allows the sheet to be pulled against a registration gate by the drive wheels versus being pushed, thereby eliminating unwanted reaction forces inherent in existing systems that push a sheet against a registration gate.

  • Patent number: 7021617
    Abstract: A substrate compiling system includes an actuator, cable and tamper device. The tamper device includes a clamp assembly. The clamp assembly is retracted and extended. The clamp assembly can be used to clamp an edge of each compiled set of substrates and transfer the compiled set to a stacking tray, platform or the like. The clamp assembly may remain in an extended position until all other substrate supporting structures no longer support the substrates and an opposing unclamped edge of the compiled set engages the stacking tray below.

  • Patent number: 6856785
    Abstract: A registration system including both a primary tamping device and a secondary scuffing device. The scuffing device includes a scuffer arm, an extending/retracting device, a drive subsystem, and an engagement control device. In various exemplary embodiments, the secondary scuffing device is retracted. The scuffing device can thus be used, when required, to register a substrate in the process direction and then retracted enabling the side tampers to cross process register the substrates. In various exemplary embodiments, substrates of varying sizes and types can be registered into common sets using the systems and methods of this invention.

  • Patent number: 6728510
    Abstract: A sheet-copy documents producing machine is provided and includes (a) sheet supply and feeding means for supplying and feeding image receiving sheets along a path and through image forming stations; (b) image forming devices mounted at the image forming stations for forming desired images on the image receiving sheets resulting in sheet-copy documents of the desired images; and (c) plural sheet-copy documents finishing devices including (i) moving parts, and (ii) at least a first sheet-copy documents finishing device and a last sheet-copy documents finishing device for each receiving, finishing and stacking the sheet-copy documents into stacks for subsequent removal by an operator. Each the sheet-copy documents finishing devices, except the last sheet-copy documents finishing device, including a movable unload-while-running safety shield assembly for protecting hands of the operator from the moving parts during an unload-while-running operation of the copy sheet documents producing machine.

  • Patent number: 5098453
    Abstract: A bed of activated carbon granules is maintained tightly packed within a fuel vapor storage canister housing by a specially designed compensator. A pair of spring loaded, nested trays move axially relative to one another and push continually into the lower face of the carbon bed to keep it packed. The trays also define a continuous, self maintaining gap that is smaller than the expected carbon granule size, preventing them from falling out in spite of the swelling of the canister housing.
