A liquid discharge apparatus includes: a liquid discharge head; a conveyer that supports and conveys a medium; a blower that is disposed on the upstream side of the liquid discharge head or the downstream side of the liquid discharge head and suppresses the change of the posture of the medium by sending the air to the medium; a temperature adjuster that is disposed on the side of the blower opposite to the liquid discharge head in the medium conveying direction and adjusts the temperature of an object to a temperature higher than the ambient temperature of the liquid discharge head or a temperature lower than the ambient temperature of the liquid discharge head; and a blast controller sends an operation stop command or an air reduction command to the blower at a blast region-pass timing at which the medium passes through a blast region of the blower.

An apparatus for folding print sheets includes two folding rollers arranged on one side of a guide plane to define a folding gap. A compressed air device is arranged on the other side of the guide plane in a region of the folding gap. The compressed air device is connected to the compressed air source and to the control unit, and includes an exit opening for the compressed air that is focused onto the folding gap. Control elements can be activated by the control unit to change the time interval during which the at least one exit opening is admitted with compressed air, and/or the cross-sectional surface of the exit opening, and the pressure of the compressed air supplied to the exit opening may also be changed by a different control element, to adapt a compressed air blast to properties of the print sheet made available to the folding gap.

An apparatus for folding of print sheets includes a compressed air device that comprises at least two segments with respectively at least one exit opening having a cross-sectional surface and directed toward a folding gap of two folding rollers. Each segment is connected to a compressed air source and a control unit, includes at least one control element and is embodied to be activated separately with compressed air.

A liquid discharge apparatus includes: a liquid discharge head; a conveyer that supports and conveys a medium; a blower that is disposed on the upstream side of the liquid discharge head or the downstream side of the liquid discharge head and suppresses the change of the posture of the medium by sending the air to the medium; a temperature adjuster that is disposed on the side of the blower opposite to the liquid discharge head in the medium conveying direction and adjusts the temperature of an object to a temperature higher than the ambient temperature of the liquid discharge head or a temperature lower than the ambient temperature of the liquid discharge head; and a blast controller sends an operation stop command or an air reduction command to the blower at a blast region-pass timing at which the medium passes through a blast region of the blower.

A rewinding machine includes a drawing assembly (1), a winding assembly, a core-change assembly (5), and pneumatic elements for interrupting the continuity of the ply at the end of a winding cycle, and for starting a new winding cycle.

A tape removal apparatus is configured for automatically removing a tape attached to an electrode roll in order to fix the electrode roll. The tape removal apparatus includes a sensing unit configured to sense the tape attached to the electrode roll, an injection unit configured to inject air toward the tape, a support unit configured to support a non-adhesive portion of the tape, and a gripper configured to fix the non-adhesive portion of the tape together with the support unit.

A sheet discharging device includes a shift tray 202 on which a sheet P1 is stacked, a discharging roller 6 that discharges a sheet P2 onto the shift tray 202, a blowing device 230 that sends air to a lower surface of the sheet P2 discharged by the discharging roller 6, a blocking member 231 that blocks air sent to the lower surface of the sheet P2 from a blowing port 230-2 of the blowing device 230, and a control unit that controls the blocking amount of the blocking member 231. The blocking amount is determined based upon sheet information including sheet-type information, sheet-size information, and sheet-thickness information, for example.

An assembly for entraining a cut end of a web in a fluid flow, the assembly comprising an arrangement for delivering a fluid flow proximal to an entrainment region where a web is cut. The assembly further has an arrangement for guiding the fluid flow and the entrained end of the web from the web entrainment region to a web delivery region.

A black wheel for transporting an ultra-thin silicon wafer may include grooves provided on a side surface of the black wheel along a circumferential direction of the black wheel. Compressed air lines are respectively accommodated within the grooves, and an air outlet of each of the compressed air lines is provided to align with a side of the ultra-thin silicon wafer close to a next process device.

A sheet feeding apparatus includes a supporting unit, a feeding unit, a side regulating portion, an air nozzle, and an air supplying unit. The air nozzle is movably provided at the side regulating portion and blows air in the sheet width direction toward at least an uppermost sheet of a sheet bundle supported on a support surface. The air nozzle is positioned at a first nozzle position for blowing the air to a first blowing position when the uppermost sheet of the sheet bundle supported on the support surface is positioned at a first sheet position. The air nozzle is positioned at a second nozzle position for blowing the air to a second blowing position below the first blowing position when the uppermost sheet of the sheet bundle supported on the support surface is positioned at a second sheet position below the first sheet position.
