A sheet material processing unit (20, 22, 24) comprises a transport system (32) for transporting sheets (12) or parts thereof from a respective input end (20i, 22i, 24i) to a respective output end (20o, 22o, 24o). A gripper unit (46) is releasably coupled to the transport system (32) and is configured for holding at least a part of one of the sheets (12). Additionally, at least one handover mechanism (47d, 47r) is provided being configured for decoupling the gripper unit (46) from the transport system (32) and providing the gripper unit (46) to a neighboring sheet material processing unit (20, 22, 24) and/or receiving a gripper unit (46) from a neighboring sheet material processing unit (20, 22, 24) and coupling the received gripper unit (46) to the corresponding transport system (32). Additionally, a sheet material processing machine (10) is presented which comprises at least two such sheet material processing units (20, 22, 24).

Machine for feeding flatwork articles to an ironer-dryer machine, the machine including loading posts (1) with a load conveyor (2) for loading flatwork articles (53); one pair of transferring grippers (6) at each loading post (1), two or more spreading grippers (7) at a pickup station movable along one transverse guide (8); an outgoing feed conveyor (9) to transfer the flatwork article (53); and a vacuum chamber (44) below the spreading grippers (7) and below conveyor (9). The spreading grippers (7) are independent of each other, to spread a flatwork article (53) at several different zones with regard to the conveyor (9), operative in one or more lanes. A suction entrance (45) of vacuum chamber (44) has associated movable separating blades (59) temporally preventing insertion of a spread flatwork article (53) into vacuum chamber (44) and a controller coordinates the movements of the transferring grippers (6), spreading grippers (7) and separating blades (59).

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.

The invention relates to a gripper bar body for a gripper bar in a gripper carriage arrangement in a machine for treating sheet material, the gripper bar body being configured to carry gripper brackets for movement between sheet gripping and sheet releasing positions. The gripper bar body is formed as a hollow structure comprising at least two different materials, the two different materials comprising at least a metal material and a composite material and the at least two different materials being at least partly arranged in a superposed manner. The resulting bar has a better resistance to wear than the ones of the state-of-the-art.

A paper-feeding cutting machine includes a frame and a machine head. The frame is provided with a paper-loading platform, a cutting table, a receiving hopper and a crossbeam, wherein a linear guide rail is disposed on both sides of the frame, and the cross beam is connected to the linear guide rail. The machine head is disposed on the crossbeam. The machine head includes a fixing plate, a cutter holder, a cutting component, a machine head lifting mechanism and a machine head rotating mechanism. A cutter holder guide rode is disposed on the fixing plate; the cutter holder is connected to the cutter holder guide rod; the machine head lifting mechanism is connected to the cutter holder; the cutting component comprises at least two cutter head assemblies mounted on the cutter holder; the machine head rotating mechanism is connected to the cutter head assemblies.

A sheet conveying device includes a first duct, a second duct, and a switching member. The first duct is disposed at a first side of a sheet conveyance passage to face a first face of a sheet passing the sheet conveyance passage and has a first air blowing port through which air is blown toward the sheet conveyance passage. The second duct is disposed at a second side of the sheet conveyance passage to face a second face of the sheet passing the sheet conveyance passage and has a second air blowing port through which air is blown toward the sheet conveyance passage. The switching member is disposed downstream from the first and second air blowing ports in a sheet conveyance direction and configured to switch the sheet conveyance passage. No pair of rollers is disposed between the switching member and each of the first and second blowing ports.

A transport device includes: a first transport body; a second transport body that is movable between a contact position and a separate position with respect to the first transport body and that nips a transported material with the first transport body at the contact position; and a transport section that includes a holder to hold a leading end portion of the transported material and that transports the transported material toward a nip region where the first transport body and the second transport body nip the transported material in a state in which the second transport body is located at the separate position. After holding of the leading end portion by the holder for the transported material transported by the transport section has been released, the second transport body nips the transported material with the first transport body and transports the transported material.
