A folding or interfolding unit of a plurality of sheets of paper comprising a first and a second folding or interfolding roll to fold, or interfold, the plurality of sheets of paper according to a predetermined folding or interfolding configuration, at a folding or interfolding zone. Each folding or interfolding roll comprises a tubular body which rotates about a longitudinal rotation axis oriented along a horizontal direction and a plurality of gripping groups integral in rotation with the tubular body. Each gripping group comprises a mechanical gripping member configured to move, at a gripping point, from a releasing configuration to a gripping configuration, where is arranged to mechanically hold the, or each, sheet up to a releasing point having a second angular position.

A drive transmission mechanism which transmits a rotational driving force to a roller to be shifted in directions of a rotational axis thereof is equipped with a rotary drive transmission member which is driven to rotate in a predetermined rotational direction, a holder which holds the roller in such a manner that the roller can slide freely in the rotational axis directions while rotating about the rotational axis, and a one-way clutch interposed between the rotary drive transmission member and the holder. The one-way clutch is configured to transmit a rotational driving force from the rotary drive transmission member to the holder, and also to permit the holder to rotate in the predetermined rotational direction relative to the rotary drive transmission member.

An apparatus and method for conveying absorbent articles may utilize a conveyor including a vacuum source in fluid connection with a deck. The deck may include a channel. The conveyor may also include a belt including a first surface, an opposing second surface, and an aperture. The second surface of the belt may be in facing relationship with the deck such that the aperture is aligned with the channel. A first row of angled teeth and a second row of straight teeth may be connected with the second surface of the belt. The first row of angled teeth and the second row of straight teeth mesh with a first gear member and a second gear member, respectively. The first and second gear members may be attached to an axle member such that the first gear member and the second gear member rotate with the axle member advancing the belt.

The combination of a dispenser and a strip of a food product and a method for dispensing the food product from the dispenser so that it can be used by a user of the dispenser. The strip comprises an elongated web of an edible material, e.g., gum, which is coiled up in a compact configuration having a free end portion. The dispenser comprises a housing for the strip, an outlet, a motor for advancing a desired length and most preferably any desired length of the free end portion of the strip out of the outlet, and a severing element for severing the desired length of the free end portion of the strip from the remaining portion of the strip to form a dispensed section of the strip which may be placed in the user's mouth while the remaining portion of the strip remains within the housing.This is a Reissue of a Patent which was the subject of Reexamination Certificate No. B1 5,579,669, dated Sep. 16, 1997, Request No. 90/004,572.
摘要:
An image forming apparatus having a transport device including a pair of timing rollers, operable to cause a leading edge of a recording sheet to abut a nip portion of the non-rotating timing rollers, and then initiate rotation to transport the sheet toward a transfer position, the transport device comprising: a motor transmitting rotational force to the timing rollers via a power transmission mechanism such that the timing rollers rotate; and a control unit controlling motor rotation, wherein the control unit activates the motor, causes the timing rollers to transport a first recording sheet at a first speed, and stops the motor once transportation is complete, and when a second recording sheet is to be subsequently transported at a different second speed, the control unit causes the timing rollers to execute an idle rotation at the second speed or at another speed, and then stopping, before beginning second sheet transportation.

A sheet picking system for picking a sheet of media includes a power source having a driveshaft. A first housing arm containing a drive gear is drivably coupled to the driveshaft. The drive gear defines a first pivot axis for the first housing arm, wherein the drive gear is driven by the driveshaft to rotate about the first pivot axis. A second housing arm contains an intermediate gear, a transmission device, and a pick roller. The transmission device is configured to rotatably couple the intermediate gear to the pick roller. The intermediate gear is positioned to be meshed with the drive gear. The intermediate gear defines a second pivot axis for the second housing arm. A link mechanism pivotably couples the first housing arm at the first pivot axis to the second housing arm at the second pivot axis.
