Downstream of the cutting section (20) a folding section (30) is provided comprising a first and a second folding rollers (31,32) counter-rotating one with respect to the other. The first and second folding rollers (31,32) are arranged to rotate about respective rotation axes (131,132), in such a way to have a first peripheral velocity vP and are configured to fold, at a folding zone (35), the aforementioned plurality of sheets (11) in a plurality of panels and to form the stack (100) of interfolded sheets. The cutting roller (25) is configured in such a way to alternately distribute the aforementioned sheets (11) between a transfer roller (45) of transfer section (40), and the first folding roller (31).

A post-processing apparatus includes: a processing unit configured to pull in a recording medium transported from an upstream apparatus and perform processing on the recording medium; a discharge unit to which the recording medium processed by the processing unit is discharged; and a lifting drive device configured to, in a case where a folded recording medium is pulled into the processing unit, move the discharge unit downward such that a height of the discharge unit is lower than a height of the discharge unit in a case where an unfolded recording medium is pulled into the processing unit.

Methods of processing a glass ribbon are provided. The method includes the step of traversing the glass ribbon through a travel path at a predetermined velocity and severing the glass ribbon to create an upstream web and a downstream web. The method further includes the step of increasing a relative velocity of a downstream edge portion with respect to an upstream edge portion to create a gap between an upstream severed edge and a downstream severed edge. In other example methods, a segment of the glass ribbon is removed to create a gap between an upstream severed edge and a downstream severed edge. In still further example methods, an upstream severed edge is directed along a second travel path to create a gap between the upstream severed edge and a downstream severed edge.

A conveyance device holds a sheet medium in a roll and includes a drive roller that feeds the sheet medium from the roll to a conveyance path; and a roll rotating unit that rotates the roll forward to convey the sheet medium toward the drive roller and in reverse to rewind the sheet medium and that has multiple drive modes with different speeds of rotation. A control unit controls driving the drive roller and the roll rotating unit, such that, when starting a reverse conveyance operation that rewinds the sheet medium, the control unit selects the drive mode to be used in the reverse conveyance operation based on a first conveyance distance, which is the distance the sheet medium is to be conveyed in the reverse conveyance operation, and the diameter of the roll stored as roll diameter information and as calculated after an immediately previous reverse conveyance operation.

A feeding unit for feeding a plastic film in packaging machines for wrapping paper rolls, including: a unit for unwinding the film from a reel; a cutting device adapted to cut the film transversely; a transfer device including, on the right and on the left side of the feeding unit, drive belts configured for engaging the upper and lower faces of the film; and a positioning device including, on the right and on the left side of the unit, a predetermined number of drive belts configured for engaging the upper and lower faces of the film. On each side of the feeding unit, the transfer device comprises two pairs of belts. On each side of the feeding unit, the positioning device comprises a third pair of belts. The three pairs of belts are actuated by independent actuators.

A post-processing apparatus includes: a processing unit configured to pull in a recording medium transported from an upstream apparatus and perform processing on the recording medium; a discharge unit to which the recording medium processed by the processing unit is discharged; and a lifting drive device configured to, in a case where a folded recording medium is pulled into the processing unit, move the discharge unit downward such that a height of the discharge unit is lower than a height of the discharge unit in a case where an unfolded recording medium is pulled into the processing unit.

The invention discloses a film-cutting device of an environmental coating machine, belonging to the technical field of mechanical engineering, which solves the existing problem that the protective film clamped by the conveyor belts are difficult to be cut. The film-cutting device of an environmental coating machine comprises frame (1), several pairs of upper conveyor belts (12) and lower conveyor belts (13), coating areas (15), wherein the film-cutting device comprises a rotation pipe (2), two transmission rods (3), film cutters (32), transverse edges (321), longitudinal edges (331), and a drive member and a spreading element arranged on the frame (1); this film-cutting device of an environmental coating machine is able to but the protective film clamped by the conveyor belts, which can improve an efficiency, reduce the usage amount of the protective film and be more environmental.

A conveying apparatus can achieve high-speed conveyance of a molded body for flattened tube fins, prevent generation of noise during conveyance, and have a smaller size. A conveying apparatus conveys a molded body for flattened tube fins obtained by providing a metal thin plate with cutaway portions, before the metal thin plate is cut into a predetermined length. The conveying apparatus includes a rotary conveying body including a plurality of protrusions that are tapered and able to enter the cutaway portions, and including a rotation shaft in a direction orthogonal to a conveying direction of the molded body for flattened tube fins in a horizontal plane, and a rotary conveying body driving unit that rotates and drives the rotary conveying body. A side surface shape of each of the protrusions is formed to have a shape to enable the protrusion to enter the corresponding cutaway portion with a space maintained in synchronization with a rotation of the rotation shaft, and retract from the cutaway portion while the protrusion comes in contact with the cutaway portion and conveys the molded body for flattened tube fins.

An image forming apparatus, includes (1) a medium holding unit that holds a recording medium; (2) a guide member configured to be movable, that sets a medium path of the recording medium fed from the medium holding unit as a predetermined path by being locked in a predetermined position, and that is unlocked by a tension of the recording medium; (3) a first conveyance member that is arranged downstream of the medium path of the guide member, and conveys the recording medium; and (4) an image forming unit that forms an image to the recording medium conveyed by the first conveyance member.
