A sheet alignment apparatus includes a supporting portion configured to support a sheet, a first alignment member configured to abut an end portion in a first direction of the sheet supported by the supporting portion and align a position of the sheet in the first direction, a first moving unit configured to move the first alignment member in the first direction, a second alignment member configured to abut an end portion in a second direction of the sheet supported by the supporting portion and align a position of the sheet in the second direction, the second direction being perpendicular to the first direction, and a second moving unit configured to move the second alignment member in the second direction, wherein the first moving unit is disposed below the supporting portion, and wherein the second moving unit is disposed above the supporting portion.

A device (1) is used for introducing a running material web (3) into a tenter machine. The device (1) comprises at least one tiltable cheek (12) which receives the material web (3). This cheek (12) is tilted by at least one control element (13) by means of at least one actuator (19). This control element (13) engages on the one hand on the cheek (12) and on the other hand on the frame (17). Angle sensors (32) record the angle between the cheek (12) and the control element (13) as well as between the frame (17) and the control element (13). These angles are delivered to calculation means (66′) for calculating the difference of the two recorded angles.

A medium stacking sheet is installed on a rotation shaft of a medium separating and stacking apparatus for stacking or dispensing a medium. The medium stacking sheet includes a body fixed to the rotation shaft and having a plurality of rotation holes which are spaced apart from each other in a rotation direction of the rotation shaft, and a plurality of vanes each including a vane pin rotatably installed in a corresponding rotation hole and a vane piece coupled to the vane pin to stack the medium.

A medium transport apparatus includes a first and a second transport path, a third transport path formed the first transport path and the second transport path merging at a merging point, a door that is displaceable between a closed state in which the door forms at least a portion of the first transport path and an opened state in which at least a portion of the first transport path is opened, and a switching section that is arranged at the merging point and that is, while the door is in the closed state, displaceable between a first state in which the second transport path is opened and a second state in which the first transport path is opened, wherein when the door is in the opened state, the switching section is displaced to a third state in which at least a portion of the second transport path is opened.

Provided is an automatic coiled material switching device, which comprises a machine table (8), a left unwinding device (81), a right unwinding device (82) and a rotatory cutting device (83); wherein the machine table is provided with a left auxiliary roller (84), a right auxiliary roller (85) and a plurality of fixed rollers; the rotary cutting device comprises a bearing seat (1), a bearing (11) arranged on the bearing seat, a rotating main body (2) arranged on the bearing, a rotating mechanism for driving the rotating main body to rotate on the bearing seat, a turning mechanism for driving the bearing seat to turn around, and a driving mechanism; the rotating main body comprises an upper part (21) and a lower part (22); a gap (23) for allowing a material to pass through is formed between the upper part and the lower part; and the rotating body is provided with a pressing mechanism for compressing the material and a cutting mechanism for cutting the material. The automatic coiled material switching device implements the automatic switching of material belts of the left unwinding device and the right unwinding device by arranging the rotating main body, rotating mechanism, the turning mechanism, the driving mechanism, the pressing mechanism and the cutting mechanism.

A convertible printed product collecting assembly includes a rotatable first rod connected to a printer, a second rod, a collecting fabric having flexibility, the collecting fabric fixed between the rotatable first rod and the second rod, wherein the collecting fabric is to receive a printed product from the printer, and two supporting legs to tiltably connect between the printer and the second rod.

A sticking device implements high-speed automatic processing of base-sheet-attached shrink-film packaging using a half-cut double-faced adhesive tape. A sticking device rolls a half-cut double-faced adhesive tape over a first sticking object that is transported on a conveyor device to stick the adhesive tape to the first sticking object and then places a second sticking object on the first sticking object and applies pressure to stick the first sticking object and the second sticking object together. The sticking device includes: a feeder device that feeds the first sticking object; a conveyor device; an adhesive-tape sticking device that has a roll body attaching part for rotatably supporting a half-cut double-faced adhesive tape with a peel-off liner, a rotary-sticking roll pressure part, and a peel-off liner collecting part; and a second sticking object sticking device that places a second sticking object on the sticking portion of the first sticking object and applies pressure.

An image forming apparatus, including: a sheet cassette; an image former; a fixer; a discharge tray; a conveyor configured to convey a sheet along a conveyance passage; a return conveyor configured to convey the sheet from a branch position between the fixer and the discharge tray to a merge position between the sheet cassette and the image former along a return passage which is branched from the conveyance passage at the branch position, passes below the sheet cassette, and merges with the conveyance passage at the merge position; a switchback roller disposed between the branch position and the discharge tray in the conveyance passage and configured to convey the sheet to the discharge tray when it rotates forwardly and to the return passage when it rotates backwardly; and an intermediate conveyance roller disposed in the return passage at a height level intermediate between the fixer and the sheet cassette.
