An apparatus (10) for folding sheets (17) and corresponding method, comprising at least a conditioning body (11), at least a folding unit (13) and at least an extraction mean (12) suitable to fold sheets (17) in sequence of variable formats, maintaining high cadences and at the same time simplifying the structure for the maintenance operations and/or format-changes.

In a paper sheet storing apparatus housed in a paper sheet handling apparatus, a storage part stores paper sheets. An ejection port ejects a paper sheet of the paper sheets stored in the storage part. A first roller is arranged near the ejection port, and is rotated in a predetermined direction by transmission of rotation caused by drive of a drive shaft so as to send out the paper sheet from the ejection port. A driven shaft is rotated in the predetermined direction following the rotation of the first roller. A second roller is arranged in a position farther from the ejection port than a first roller, and is rotated in the predetermined direction by transmission of rotation of the driven shaft so as to sequentially feed, to the first roller, the paper sheets from a paper sheet positioned in a lowest layer among the paper sheets.

A drive transmission device includes a drive transmission member and a rotation shaft. The drive transmission member has an insertion portion. The rotation shaft includes a press-fit portion and another flat portion. The press-fit portion press-fits into the insertion portion after insertion of an axial tip of the rotation shaft into the insertion portion and includes a press-fit flat portion parallel to an axial direction of the rotation shaft. The other flat portion is at a position closer to the axial tip than the press-fit flat portion. The insertion portion has an inner-wall flat portion to contact the press-fit flat portion when the press-fit portion is press-fitted into the insertion portion. The other flat portion is parallel to the press-fit flat portion that has a distance from an axial center of the rotation shaft smaller than the press-fit flat portion.

A suspended surface assembly is provided having a trainable surface support element, a spindle component configured for training of the trainable surface support element therearound, a take-up action module configured to drivingly rotate the spindle component to thereby effect winding of the trainable surface support element onto the spindle component or to effect unwinding of the trainable surface support element from a partially or fully wound-up condition, and a lift complex for adjusting the vertical position of the trainable surface support element and the spindle component, the lift complex including a motive power element operable to both drivingly rotate the spindle component and to drivingly raise and lower the trainable surface support element and the spindle component. A method for operating the suspended surface assembly is also provided.

A paper medium skew correcting device includes: a support including a pair of fixed stop plates arranged in parallel; a skew correcting tapered roller assembly including a tapered roller, a reference plate located at a large end face of the tapered roller and a transmission shaft a tapered cover plate covering on the tapered roller with a skew correcting passage formed between an inner wall of the tapered cover plate and an outer wall of the tapered roller, an auxiliary pressure roller mechanism is mounted on an outer wall of the tapered cover plate and is configured to press a paper medium against the outer wall of the tapered roller tightly, the tapered cover plate is provided with an opening; and a driving transmission assembly. The device fully uses combined action of centrifugal force and friction force to realize skew correction and conveying of the paper medium.

The present disclosure is in one aspect to a dispenser for rolled sheet materials. The dispenser includes a feed roller that is rotatably mounted to a housing of the dispenser housing, and that is configured to feed a predetermined amount of sheet material from the supply of sheet material through a discharge provided along the housing of the dispenser. The dispenser also has a feed roller drive assembly with a drive motor, and a belt transmission assembly. The belt transmission assembly has a drive belt coupled to the drive motor and to the feed roller such that rotation of the feed roller is driven by operation of the drive motor.

A motorization group of reels in a machine for winding plastic film onto bobbins, wherein at least two spindles are positioned on a rotating plate around a central shaft constrained to a frame of the machine, a motor being operatively coupled to each of the spindles, in the motorization group each of the motors being constrained to the frame and connected to each of the spindles by a belt transmission which comprises a central deflector unit aligned with a central shaft outside the frame, toothed belts connecting the central deflector unit, on the one hand, to the spindles, and on the other hand, to the motors.

A lifting system for inner yarn rails is provided. The system includes an in-air conveying rail, and a carrier unit, wherein the in-air conveying rail is configured to convey the carrier unit, and the carrier unit is configured to carry a winding package; an inner yarn-carrier-lifting section is arranged on the in-air conveying rail, the inner yarn-carrier-lifting section is positioned on both sides of a twisting machine; when the inner yarn-carrier-lifting section rises, it communicates with the in-air conveying rail; when the inner yarn-carrier-lifting section descends, it approaches the position of a spindle bucket of the twisting machine.

Various apparatus embodiments include first, second, third and fourth shafts, and further include a first movable shaft having a first movable axis that is movable between a first axis position and a second axis position, and a second movable shaft having a second movable axis that is movable between a third axis position and fourth axis position. At least one linkage connects the first movable shaft to the second movable shaft. A motor linkage connects the at least one linkage to at least one motor for providing simultaneous movement of the first and second movable shafts.

A document conveying apparatus includes a first conveying roller for conveying a document stacked on the document tray, a second conveying roller, provided at a downstream side with respect to the first conveying roller, for conveying a document stacked on the document tray, a separation roller, provided at a downstream side with respect to the second conveying roller, for performing separation operation of the document, a driving force transmission mechanism for transmitting the driving force to a driving shaft of the first conveying roller, a driving shaft of the second conveying roller, and a driving shaft of the separation roller, and a first blocking mechanism, provided between the first conveying roller and the driving shaft of the first conveying roller, for blocking a driving force transmitted to the driving shaft of the first conveying roller, for a first certain period of time.
