Abstract: An improved sheet accumulator for stacking serially fed sheets transported on a paper path includes a guide deck. Above the guide deck, a plurality of parallel belts are positioned to provide a driving force for sheets on the deck. Within the accumulator, a ramp apparatus is positioned across the paper path whereby sheets driven by the belts on an upstream portion of the accumulator deck are driven over the ramp apparatus and deposited in an accumulating region of the accumulator deck on a downstream side of the ramp apparatus. Sheets are stopped by an accumulator stop mechanism located at a downstream end of the accumulating region that prevents movement of sheets by the belts while sheets for an accumulation are being collected. When an accumulation is completed, the accumulator stop mechanism allows sheets to be transported from the accumulating region.

Abstract: An improved apparatus and method for cutting and processing sheets from a web of printed material comprising first and second side-by-side portions of sheets along a length of the web. A first transport is arranged to transport the web in a first horizontal direction. A web splitter splits portions of the web as they are transported on the first transport. An extended path transport, in line with the first transport, transports the second portion of the web in an extended path. A direct path transport, in line with the first transport, transports the first portion of the web on a more direct path. As a result of these different paths sheets within the first and second web portions are re-sequenced in a manner suitable for processing by downstream modules, such as a right angle turn module.

Abstract: An apparatus for inverting the spatial orientation of sheet material from a desired input to a desired output orientation. The apparatus includes a cage assembly, a torque drive mechanism operative to rotate the cage assembly about a rotational axis and a sheet conveyance mechanism mounting to the cage assembly for conveying sheet material along the rotational axis of the cage assembly. The torque drive mechanism is adapted to assume input and output positions about the rotational axis wherein each position corresponds to the desired input and output orientations of the sheet material. The sheet conveyance mechanism is, further, adapted to: (i) receive sheet material when the cage assembly is in the input position, (ii) eject sheet material when the cage assembly is in the output position and (iii) retard the movement of the sheet material in response to rotation of the cage assembly by the torque drive mechanism.

Abstract: The present disclosure provides an improved system and method that reduces fulgurites and their effects in a fuse. The fuse element can be at least partially coated with a high temperature elastomeric compound, such as a silicone, that can substantially withstand the heat of the current sufficient to “blow” the fuse and associated arcing, if any, and not allow the local melting of the sand to form the fulgurite. Thus, the elastomeric compound shields the sand from the arcing. The arcing can be suppressed faster by not allowing fulgurites to form near the arc to provide a channel for the arc. The arc can be suppressed quicker with less heat without the channel. In general, if a fulgurite is formed, it is formed near the beginning of the elastomeric coating that is distal from another part of the exposed fuse such that arcing, if any, is reduced.

Abstract: An inserter input system including a web feeder providing a web of printed material to be split by a web slitting knife along the web's direction of travel. The split web is then cut transverse to the direction of travel by a rotary cutter operating at a first velocity, resulting in side-by-side individual sheets. Downstream of the rotary cutter, a right angle turn mechanism receives each of the side-by-side sheets and reorients them by ninety degrees. Further the right angle turn reorients the sheets into a serial shingled arrangement. A high speed separation nip pulls individual shingled sheets out from the shingled arrangement. The speed of the separation nip is such that a predetermined gap between the previously shingled sheets is formed.

Abstract: A method and system are disclosed for delivering and feeding a stack of paper to a high-speed sheet feeder. A sheet handling cart is removably connectable to a docking station attached to the high-speed sheet feeder. The sheet handling cart comprises a paper trough which is liftable from the rest of the cart. The paper trough has a trough bottom which longitudinally forms an elongated opening narrower than the bottom of the paper trough, the elongated opening being dimensioned to accommodate a conveyor belt that will protrude upward through the rectangular opening, after the paper trough is lifted from the rest of the cart, in order to advance the stack of paper toward the high-speed sheet feeder.

Abstract: A method and system for sheet accumulating wherein a web of material is cut into groups of cut sheets and a right-angle transport device is used to collate the cut sheets into packets. Because the cut sheets in each packet are moved into and out of the right-angle transport device in separate paths with different pathlengths, the cut sheets overlap with each other by an overlapped amount as they exit the right-angle transport device. A path deflector having a curved path is used in at least one of the paths in order to reduce the pathlength difference, thereby increasing the overlapped amount.

Abstract: A flexible buffer transport system for staging accumulated documents for transfer to a synchronous downstream transport. Control of movement of accumulations in the buffer being independent of the length of the documents. The system includes a plurality of roller nips in series. The roller nips are spaced a uniform distance apart. Each of the roller nips are driven by an independently controllable motor in communication with a controller. Position sensors also communicate with the controller. The sensors sense positions of lead and trail edges of accumulations of documents within the buffer transport system. For each sampling period in the operating cycle and for each roller nip, the controller determines motion control. First, the controller determines which nips should be slaved together based on which are needed to control a particular accumulation of documents under its control.

Abstract: A buffer transport system for staging accumulated documents produced by an input module of an inserter system. The system including a plurality of roller nips in series. Each of the roller nips are driven by an independently controllable motor in communication with a controller. The series of roller nips form stopping stations along the length of the buffer transport. Each of the stopping stations has a uniform length and is comprised of two or more of the roller nips. The roller nips in any given stopping station are electronically geared together under the control of the controller. The controller controls stopping stations to transfer accumulated documents within the stopping stations to a next downstream stopping station when it is sensed that the next downstream stopping station is open. If the next downstream station from a given station is not open, then the controller does not instructs the station to transfer documents downstream.

Abstract: A buckle chute having a deflector disposed in front thereof to allow a sheet of document to enter the buckle chute channel or to deflect the sheet away from the channel. The deflector is pivotally linked to two actuator arms on the left and right sides of the buckle chute. Each actuator arm is pivotally linked to a bell crank, which is also pivotally linked to a linking member. The linking members are further connected to a lever such that they can be moved in opposite directions from left to right or from right to left so as to cause the bell cranks to rotate in opposite directions. As such, the actuator arms are simultaneously moved toward or away from the front side to control the deflector position.

Abstract: The present invention concerns a document processing and collating machine having a feeding path leading to at least one document conveying devices having one or more document accumulating bins for receiving a series of documents that are fed downstream in spaced apart collations with documents in shingled relationship. The document accumulator bins have an intermediate conveying and diverting apparatus which is momentarily engaged to cause a leading end of a shingled collation of documents to be diverted into a document accumulating bin where the documents are registered at their common leading end at a nip of a set of downstream conveying rollers that are stopped during the registration process.

Abstract: A buckle chute having a stop to cause a sheet of document entering the buckle chute to buckle for making a folded edge. The ends of stop are threadably engaged with two lead screws, which are mechanically linked together by a chain, so that the lead screws can be simultaneously turned in order to adjust the position of both ends of the stop. Each end of the stops has a split nut with grooves for engaging with the threads of the lead screws. The split nut can be disengaged from the threads so that the position of one or both ends of the stop can be adjusted.
