An inkjet printing machine for printing individual sheets comprises at least one printing station and a transport system defining a transport track for transporting the individual sheets through the printing station, along a transport direction. The transport system comprises a plurality of gripper conveyors (150) running along the transport track for holding the individual sheets during a printing process in the printing station. Each of the gripper conveyors (150) comprises an energy storage (161) for providing energy for operating a gripper mechanism (171) of the gripper conveyor (150). The printing machine allows for efficient and flexible handling of individual sheets, in particular large format sheets of materials such as corrugated cardboard or other materials that have a certain degree of inherent stability.

In an example, a clamp may include a chassis, a swingarm disposed on the chassis, a clamp wheel disposed on a first end of the swingarm to engage with a drag portion of the chassis, and an auxiliary bias member to exert a force against the clamp wheel to resist a rotation of the clamp wheel. The force may periodically increase in magnitude.

A conveying device for conveying a sheet-like material of the present invention includes: a rail portion arranged in a loop shape; a plurality of travelers; a linear motor for circulating the travelers along the rail portion; and a pad attached to each of the travelers, wherein the pad circulates in at least one horizontal plane while holding the sheet-like material on the pad, thereby conveying the sheet-like material.

A feed appliance for feeding products to a further processing appliance includes a standby circulatory apparatus with a takeover station and with several transport units that are circulatorily movable independently of one another for each receiving a product at the takeover station, a provision conveyor for feeding the products to the takeover station, and a control device for controlling the feed of the products and of the transport units into a takeover section of the takeover station and for controlling the takeover of the fed products by the transport units. The standby circulatory apparatus for creating a gapless product stream includes a release device for the cyclically controlled release of individual transport units into the takeover section. For this, the control device is designed to release a transport unit only given a feed of a cyclically correct product into the takeover section.

A running rail (1) for a conveyor system, the running rail (1) having a cross-sectional profile comprising at least three interconnected profiled portions which comprise a first profiled portion (2), laterally open to the outside, for receiving first rollers (32) of a carriage (30), a second profiled portion (3), laterally open to the outside, for receiving second rollers (33) of a carriage (30), a third profiled portion (4), open in the vertical direction, for receiving third rollers (34) of a carriage (1), wherein the first (2) and the second profiled portion (3) are mirror symmetrical to a vertical central plane (40) of the running rail (1).

A post-processing apparatus for post-processing paper discharged from an image forming apparatus comprises: a paper discharging roller for conveying both first and second paper sequentially discharged from an image forming apparatus to an intermediate loading part; a main paddle part for conveying the first and second paper loaded on the intermediate loading part to a compiling region; a reverse roller for conveying, together with the main paddle part, the first and second paper to the compiling region; and a binding part for processing the first and second paper conveyed to the compiling region, the paper discharging roller allows the first paper to stand by on a standby path, and conveys the first and second paper to the intermediate loading part in a state in which the leading end of the first paper protrudes further than the leading end of the second paper.

A main mover and sub mover are made to run while changing a relative distance of the sub mover with respect to the main mover to change contact positions of cams and cam followers based on a holding position of a sheet member detected by a position detection device to thereby change a position in a horizontal plane of a holder and correct a holding position of the sheet member held at the holder to a preset reference position.

In an example, a clamp may include a roller disposed on a swingarm, a slide disposed on the swingarm that may apply friction against the roller in a first position and in a second position, a cam to engage with the slide, and a latch to retain the slide in the second position. The slide may move from the first position to the second position as the slide moves along the cam, and the slide may apply a greater friction against the roller in the second position than in the first position.
