A printing system includes at least one main printer arranged to print images onto main sequence sheets that are passed sequentially through the main printer; an inserter arranged to insert individual sheets as insert sheets into a stream of main sequence sheets that have left the main printer, thereby to form a mixed sheet sequence; and a conveyer arranged to convey the sheets of the mixed sheet sequence one by one towards an output unit. An insert sheet printer is connected to the inserter for printing the insert sheets and forwarding them to the inserter.

A sheet processing apparatus includes a sheet conveyance passage, a sheet circulation passage, a first conveyor, a second conveyor, a third conveyor, and circuitry. In the sheet circulation passage, a sheet is circulated to be overlaid with a following sheet in the sheet conveyance passage. The circuitry circulates the sheet in the sheet circulation passage to overlay the sheet with the following sheet conveyed after the sheet in the first sheet conveyance passage, at an upstream position of the first sheet conveyance passage, and adjusts a sheet conveyance speed of the third conveyor to circulate the sheet, based on a reduction amount that is obtained when a preceding amount of a leading end of the following sheet with respect to a leading end of the sheet is reduced while the following sheet is temporarily stopped due to a temporary stop of the first conveyor.

In a method for producing a collection (20) of pre-products by inserting a first pre-product (1) into a second pre-product (3), it is provided according to the invention that a first pre-product (1) and a second pre-product (3) are provided, wherein the second pre-product (3) has a wrapping fold (4) with a fold inner side (5). The second pre-product (3) is conveyed into an insertion position, in which the second pre-product (3) is opened and faces with the fold inner side (5) toward the first pre-product (1). The first pre-product (1) is conveyed into the opened second pre-product (3) and against the fold inner side (5) so as to form the collection (20), the second pre-product (3) assumes the conveying direction of the first pre-product (1), and the collection (20) is provided for further processing.

The present applications relates to techniques and equipment to control the alignment of cut sheets of paper that are transported in parallel in an inserting system prior to their assembly into a document and inserted into an envelope. The alignment of the parallel sheets is adjusted by commanding incremental position changes to servo drive motors used to control the position of the parallel sheets during their transport through a hold module of the inserting system.

An inspection device for a layer material has a layer conveyor and a drive to pick up an anode or cathode layer by a pickup from a transfer location and bring it to a delivery location. The layer turner delivers a single anode or cathode layer from its pickup to a stacking table at the delivery location. The drive aligns the pickup and the stacking table relative to each other depending on a signal based on processing of a first or second image feed. A first image sensor is aligned between the transfer location and the delivery location to perform a first image feed when the pickup of the layer turner passes the first image sensor. A second image sensor is aligned between the transfer location and the delivery location to perform a second image feed when the pickup of the layer turner passes the second image sensor.

A stacker includes a placement part that stacks thereon sheets discharged from a discharge port by a conveyor that conveys the sheets; a side guide that regulates edges of the sheets in a width direction intersecting a discharge direction of the sheets; a guide driver that moves the side guide along the width direction; and a controller configured to control the guide driver to position the side guide at a position where the sheet discharged from the discharge port is supported from below by the side guide.
