An image forming apparatus includes: an image forming part that forms an image on a paper sheet; a first conveyance path that conveys the paper sheet on which the image is formed and that includes a primary conveyance path; a second conveyance path that reverses the paper sheet and includes a reverse conveyance path; a connecting conveyance path that connects the second conveyance path to the first conveyance path, and, before reversal at a time of conveyance to the second conveyance path, sends the paper sheet to the first conveyance path, starting from one edge of the paper sheet; and a return conveyance path that connects the second conveyance path to the first conveyance path, and, after the reversal at a time of conveyance to the second conveyance path, sends the paper sheet to the first conveyance path, starting from the other edge of the paper sheet.

A device for removing or branching-off product segments from a product flow in the energy-cell manufacturing industry, characterised in that the device has at least one switchable dispenser which is set up to remove a product segment from the product flow as a result of a switch signal.

A sheet ejection device includes: a paper ejection chain (22b) for conveying paper (W); a first pile (26) or a second pile (26b) having loading plates (27a or 27b) arranged in a multistage manner and used for loading the paper ejected from the paper ejection chain; a first beam sensor (62a or 62b), a second beam sensor (63a or 63b), and a third beam sensor (64a or 64b) for detecting an intrusion into the first pile or the second pile. The sheet ejection device further comprises: a plate upper-limit position detection sensor (58a or 58b) for detecting that the loading plate has been positioned at a plate upper-limit position (L2); and a control device (50) for, based on the detection signal of the plate upper-limit position detection sensor, neglecting (disabling) a command for stopping a driving device (printing machine), the command is issued by the first to third beam sensors.

A diverter conveyor includes a frame supporting an upper conveyor that has an upstream end and a downstream end and that is configured to carry sheets in a first, downstream, direction. A plurality of nip rollers are mounted on the frame upstream of the upstream end of the upper conveyor and are spaced from the upstream end of the upper conveyor by a gap. The nip rollers feed the sheets along a main path to the upstream end of the upper conveyor. A rejection conveyor is supported by the frame and has a portion beneath the gap and extends away from the upper conveyor at an acute angle. A plurality of paddles are mounted at the first gap, and an actuator is operably connected to the paddles and configured to shift the paddles from a first position out of the main path to a second position in the main path.

An image forming apparatus includes: an image forming part that forms an image on a paper sheet; a first conveyance path that conveys the paper sheet on which the image is formed and that includes a primary conveyance path; a second conveyance path that reverses the paper sheet and includes a reverse conveyance path; a connecting conveyance path that connects the second conveyance path to the first conveyance path, and, before reversal at a time of conveyance to the second conveyance path, sends the paper sheet to the first conveyance path, starting from one edge of the paper sheet; and a return conveyance path that connects the second conveyance path to the first conveyance path, and, after the reversal at a time of conveyance to the second conveyance path, sends the paper sheet to the first conveyance path, starting from the other edge of the paper sheet.

A device for ejecting 1 a flat object 101 during the conveyance thereof along a conveying path 102 includes an inlet conveyor 10 and an outlet conveyor 20 which are successively arranged one after the other along the conveying path 102. At least the downstream part 11 of the inlet conveyor 10 is orientably mounted for pivoting between a conveying position and an ejecting position and at least the upstream part 21 of the outlet conveyor 20 is orientably mounted for pivoting between a conveying position and an ejecting position.

A device for storing a sheet pile in a converting machine (10) comprises a transfer mechanism (28) for delivering sheets (22) into a piling area (26) of the device (22), and a sampling plate (44) which is adjustable between a sampling position and an access position, wherein the top of the piling area (26) is covered by the sampling plate (44) when the sampling plate (44) is in the sampling position and the top of the piling area (26) is free when the sampling plate (44) is in the access position.
