An image reading apparatus includes a reading device that reads an image on a document that is conveyed through a first conveying path, a switching guide that is supported so as to be able to rotate about a rotation axis, guides the document to a second conveying path by being disposed at a first position, and guides the document to a third conveying path by being disposed at a second position; and a roller that conveys the document to one of the second conveying path and the third conveying path after the reading device reads the document, wherein the second conveying path is arranged above a plane that is formed along the first conveying path, and the rotation axis is arranged below the plane and on an upstream side of a vertical plane that comes in contact with an edge of a downstream side of the roller.

An equipment of accumulation of sheets forms a stack of sheets on an accumulation plane by means of driving belts and diverters arranged along the path of the sheets and jump on the accumulation plane. The height of the jump is modified by shifting vertically the accumulation plane with respect to the diverters according to number and/or thickness of the sheets. The diverters can be shifted according to the length of the sheets to be accumulated, while a series of arrest lugs delimits at the rear the area of collection of the sheets and a forwarding mechanism with a pair of output rollers forwards the stack of accumulated sheets when the lugs are released.

A winding apparatus is disclosed for winding material around a core of flat shape rotated around a rotation axis carried by a crank that is in turn carried by another crank, the three rotation axes of the core and of the two cranks being motorized independently by respective electric cams, with three distinct laws of motion programmed to cancel the variations in position and speed of the material entering the core. The winding apparatus is used for the production of electric energy storage devices.

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 medium transporting apparatus including a transport belt that transports a medium while suctioning the medium against a transport surface, a first tray on which the medium transported with the transport belt is mounted, and a transport roller configured to move between a transporting position that nips the medium with the transport belt, and a retracted position that is a position distanced away from the transport belt with respect to the transporting position, in which the transport roller is positioned at the retracted position when a single medium is transported with the transport belt and is positioned at the transporting position when a plurality of mediums in a superposed state are transported with the transport belt.

The invention relates to a turning apparatus for a production plant (2) for sanitary products, in particular adult or baby diapers, the turning apparatus having a drum (12) which rotates about a geometrical drum rotational axis (11), and at least one plate (14) which is spaced apart radially from the drum rotational axis (11) and is coupled to the drum (12), which plate (14) comprises a suction face (15) for the transport of sanitary material pieces (16), which suction face (15) holds the respective sanitary material piece (16) by means of a vacuum during the transport, the plate (14) having a geometrical vertical axis (17) which runs radially with respect to the drum rotational axis (11), the plate (14) receiving the sanitary material piece (16) with a first orientation about the vertical axis (17) in a first transfer region (18), and transporting the sanitary material piece (16) from the first transfer region (18) to a second transfer region (20) along a setpoint transfer path (19) which runs in the circumferential direction around the drum rotational axis (11), the suction face (15) being rotated with the sanitary material piece (16) about the vertical axis (17) during the transport, the plate (14) outputting the sanitary material piece (16) in the second transfer region (20) with a second orientation which is different than the first orientation about the vertical axis (17). It is proposed that, during the receiving and/or outputting, the plate (14) carries out a non-linear compensation movement relative to the drum (12) with a radial movement component.

Webs include print patterns repeated at print pitches. The first web is intermittently fed at the print pitch of the first web by a first pair of feed rollers to a section. The second web is fed at the print pitch of the second web by a second pair of feed rollers to the section. The first web and the second web are fed in a superposed state by a downstream pair of feed rollers from the section. A first tension roller and a second tension roller engaging with the first web and the second web are biased by a biasing member via a linkage.

In a roller-style feed mechanism, a feed roll is opened and closed for the purpose of pilot release using a direct-coupled servo motor as opposed to pneumatic or hydraulic cylinders. The electronically controlled servo motor drives a rotating shaft with eccentric cams that interact with cam followers causing the feed rollers separate for pilot release. The cam followers produce a force sufficient to overcome nip pressure when separating the feed rollers during pilot release. The electronically controlled servo motor is preferably operative to sense the point where the cams contact the cam followers after the upper feed roller is closed on the feed material, and automatically sense resistance to determine where the upper roll begins to lift so as to compensate for different material thicknesses.
