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.

A sheet feeding apparatus includes a sheet supporting unit, a sheet feed unit, an air separation unit configured to separate the uppermost sheet by blowing the air onto a side surface of the sheet bundle supported by the sheet supporting unit, a velocity detection unit configured to detect actual velocity of a sheet fed by the sheet feed unit, a drive load detection unit configured to detect an actual drive load for feeding the sheet by the sheet feed unit, and a controller configured to control the sheet feed unit and the air separation unit. In a case where the sheet is fed by the sheet feed unit, the controller is configured to control an operation of the air separation unit depending on the actual velocity of the sheet detected by the velocity detection unit and the actual drive load detected by the drive load detection unit.

The present invention relates to a thread guide element for a yarn monitoring and/or yarn processing unit as well as to a yarn clearer for a workstation of a textile machine with at least one thread guide element.

A tension-inducing shaft system includes a shaft, two shaft caps, and a biasing mechanism. A bore extends through the shaft between two ends of the shaft. The shaft caps are positioned on the two ends of the shaft. Each shaft cap includes a collar having a size that is larger than the bore, a keyed end, and an anchor. The biasing mechanism is arranged inside the bore and is coupled to the anchors of the shaft caps so that the biasing mechanism exerts inward forces on the shaft cap. The keyed ends of the shaft caps can be coupled to a housing so that the shaft caps do not rotate with respect to the housing. The shaft is configured to rotate with respect to the shaft caps such that, when the keyed ends are coupled to the housing, the shaft is capable of rotating with respect to the housing.

A device for manufacturing an electrode assembly for removing foreign particles through air is provided. The device includes a winding portion; an electrode transfer line; an air blower installed on a top portion of the device and blowing air to a bottom portion of the device; and an outlet for discharging air moved to the bottom portion by the air blower.

A paper sheet storage container capable of accurately taking out paper sheets one-by-one. A paper sheet group is held by a paper sheet placing table and holding members, while the paper sheet placing table is being biased upward by an elastic member so that the position of an uppermost paper sheet of the paper sheet group placed on the paper sheet placing table is substantially the same position as the positions of holes through which air flows. In this state, in the paper sheet storage container, air is blown from a side to the uppermost paper sheet of the paper sheet group placed on the paper sheet placing table thereby allowing the uppermost paper sheet to be brought into a state in which the vicinity of the center thereof has been raised.

A medium feeding device includes a container member that accommodates sheet media, a discharging member disposed further than the media accommodated in the container member in a discharging direction in which the media are discharged, a hand-over member disposed above the container member at a position closer to the discharging member, a floating device disposed on a side of the media accommodated in the container member, and an auxiliary suction member disposed above the container member on a side of the hand-over member opposite to a side closer to the discharging member in the discharging direction in which the media are discharged. The auxiliary suction member is disposed closer to the hand-over member than to an end portion of the media accommodated in the container member opposite to an end portion of the media located closer to the discharging member.

A post processing device includes: a processing tray that supports media on which post processing is performed; a post processing section configured to perform post processing on the medium supported by the processing tray; and a blowing section configured to blow air at the medium supported by the processing tray, wherein a control section for controlling the blowing section sets a blowing amount by the blowing section to a first blowing amount when the number of sheets of medium supported by the processing tray is less than a predetermined set number of sheets and sets a blowing amount by the blowing section to a second blowing amount, which is larger than the first blowing amount, when the number of sheets of medium supported by the processing tray is equal to or greater than the set number of sheets.

A method for taking out paper sheets that is capable of accurately taking out paper sheets (for example, separator cards) stored in a paper sheet storage container one-by-one at low cost. In this paper sheet taking-out method, air is blown from the side of or below the paper sheet while it is in a spread state, so that the upper surface of the paper sheet is raised. In this state, sucking the upper surface of the paper sheet by a suction mechanism allows for taking out the paper sheet with high accuracy.

A sheet feeding apparatus includes a tray configured to support a sheet, a lifting unit configured to raise and lower the tray, an air blowing unit configured to blow air to a side edge of the sheet supported by the tray to float the sheet, an attraction and conveyance unit configured to execute a feeding operation of attracting and feeding the floated sheet, an upper surface detection unit configured to detect a lower state where an upper surface of the sheet is below a detection position, and a control unit configured to control the lifting unit and the attraction and conveyance unit. The control unit is configured to execute a mode in which the tray is raised by the lifting unit for a second time longer than a first time in which the lower state is detected.
