摘要： Apparatus for feeding sheets seriatim from a sheet supply stack. The apparatus comprises a sheet feed head assembly including a plenum, a vacuum source in flow communication with the plenum, and a mechanism, such as a feed belt, for example, associated with the plenum for urging a sheet acquired by vacuum in a sheet feeding direction away from the sheet supply stack. The sheet supply stack is supported, for example in a hopper on a support platform, so as to maintain the topmost sheet in such stack at a predetermined level in spaced relation with respect to the urging mechanism of the sheet feed head assembly. A first positive air supply directs a flow of air at the sheet supply stack to levitate the top several sheets in the supply stack to an elevation enabling the topmost sheet to be acquired by vacuum from the sheet feed head assembly plenum; and a second positive air supply directs a flow of air at an acquired sheet to assure separation of any additional sheets adhering to such topmost sheet.

摘要： A sheet feeder having a platform for supporting a stack of sheets, a feed head assembly for feeding sheets seriatim from the top of a sheet supply stack on the platform, a mechanism for moving the platform relative to the feed head assembly, and a device for controlling operation of the platform moving mechanism. The control device for the platform moving mechanism includes a sensor for detecting marginal edges of sheets in the sheet stack on the platform, and producing a signal indicative of sheet edge detection. Additionally, a sensor is provided for detecting the location of the topmost sheet on the sheet stack on the platform, and producing a signal indicative of such top sheet location detection. A signal is set representative of the top of the sheet stack being in proper operative relation to the feed head assembly, this set signal being based on the signal from the top location sensor for the particular location of the top of the stack when the marginal sheet edge detection signal is first produced. Periodically thereafter, a control signal is produced for actuating the sheet stack supporting platform moving mechanism until the signal indicative of detection of the topmost sheet from the top location sensor is substantially equal to the set signal.

摘要： A device for transporting material, in the form of discrete sheets, seriatim to a stack of discrete sheets, and subsequently seriatim away from such stack. The discrete sheet material transport device comprises a support for a stack of discrete sheets. The stack support includes a first stop for a first marginal edge of a discrete sheet, and opposed second and third stops for opposed marginal edges of a discrete sheet perpendicular to the first marginal edge of such discrete sheet. Discrete sheets are delivered seriatim to the vicinity of the stack support and are urged in a first direction into engagement with the first stop to form a stack of discrete sheets on the stack support. The discrete sheets are subsequently urged seriatim in a direction opposite the first direction to remove discrete sheets seriatim from the stack on the stack support. The second and third stops are located to accurately position the stack of discrete sheets on the stack support. Further, the second and third stops are substantially simultaneously oscillated to maintain such stack in the accurate position as such discrete sheets are urged to and from the stack on the stack support.

摘要： Apparatus for wrapping and sealing stacks of paper sheets from the output of high speed copiers and printers. The apparatus includes a paper handling assembly, a sealing assembly, rolls of a plastic film material, and a tote or hopper system. The paper handler permits single sheet feeding and inverting of sheets when desired. The sealing assembly wraps the stack of sheets with the plastic film and lowers a U-shaped sealing bar assembly around the wrapped package to seal simultaneously three sides thereof. Two of the three sides are parallel and near the edge of the plastic film, and are sealed with non-severing type seams. The third side is perpendicular to the other two sides and is sealed with a severing type seam. The severing type seam is made with a heating element on one side of the sealed plastic layers, and a non-heated cut-off wire located on the other side. The cut-off wire is also used to control the temperature in the seal area.

摘要： The adjustment method aligns printing engines in a print assembly that is capable of printing on a receiver to form one or more final prints and includes corrections for cross-track misregistration. These adjustments are made in one embodiment by aligning two or more printing engines in an x and y direction relative to a paper path cross track reference and then aligning each printing engines in a cross track direction (z direction) relative to the paper path cross track reference based on measurements in the cross track direction (z direction) relative to the paper path cross track reference.

摘要： A print engine synchronization method enables the movement of a first print engine dielectric support member (DSM) having one or more image frames as well as the movement of a second print engine DSM having one or more image frames by monitoring a first frame signal from the moving first print engine DSM and a second frame signal from the moving second print engine DSM. An offset is determined for each of corresponding pairs of frames from the one or more image frames of the first and second print engine DSM and the determined offset for each corresponding pair of frames is compared to a target offset to maintain synchronization between the first and second print engines on a frame by frame basis by adjusting a second print engine DSM velocity based on the comparison of the determined offset and the target offset.

摘要： A sheet feeder comprising a platform for stacking sheets and feed head assembly at the front of the platform for acquiring individual sheets from the stack and feeding separate sheets into a sheet handling machine. The feed head assembly is comprised of a vacuum plenum having a port plate, across which a perforated belt(s) moves in a closed loop. The port plate includes ports wherein the air flow through some of the ports is restricted by an intermediate plate positioned within the plenum which, in turn, has a restrictive passage therein through which air from the restricted ports must flow into the plenum.

摘要： A method for reducing artifacts on a toned sheet caused by buckling during fusing includes providing two compliant rollers that form a fusing nip for fusing the toned sheet. A control drives at least one of the rollers at a nominal speed to cause the rollers to rotate and there after increasing the roller speed to high speed prior to the sheet arriving at the fusing nip and after the sheet is in the nip decreasing the drive speed back to the nominal speed.

摘要： A method of increasing productivity in a reproduction apparatus includes providing a first print engine and a second print engine. The engines are coupled by an inverter so that each sheet of a plurality of receiver sheets is selectively printed in an invert mode or a non-invert mode. A difference of a travel time of a first receiver sheet in an invert path through the inverter in the invert mode as compared to a travel time of a second receiver sheet in a non-invert path through the inverter in the non-invert mode is adjusted so that the difference is an integral multiple of a period between the receiver sheets.
