A post-processing apparatus includes a side edge part removing portion that removes a side edge part from a sheet; a side edge part housing portion that houses the removed side edge part and is able to be pulled out from an apparatus body; a guide plate that is inclined in a direction intersecting with a moving direction of the side edge part and guides the removed side edge part along the moving direction to the housing portion; and a second guide plate that is arranged between the housing portion and the guide plate, and is transformable into a first form having substantially mountain-shaped inclined surfaces in which both end portions of the second guide plate along the moving direction are lower than a center portion thereof, and a second form having substantially valley-shaped inclined surfaces in which both the end portions are higher than the center portion.

An arrangement for cutting paper board sheets. The arrangement includes a first wheel and a second wheel. The first wheel is arranged to rotate around a first axis. The first wheel includes a knife and an element formed as a circular arc with substantially the same radius as the peripheral surface of the first wheel and a corresponding recess formed in the first wheel peripheral surface. The element is pivotally arranged around an axis substantially parallel to the first axis in the recess and the knife is extending from the element such that the position of the knife in relation to the first wheel is adjusted by pivoting the peripheral element by adjustment structure arranged to secure the peripheral element in the desired position. Also, a machine can include the arrangement.

In order to reliably cut a sheet even when the width of the sheet is changed while shortening cutting time, the position of an end portion of the sheet is sensed and a cutting range is set according to the sensed position of the end portion.

There is provided a cutting mechanism including: a cutter blade that is capable of cutting a medium; a cutter unit to which the cutter blade is attached; and a rack gear that supports the cutter unit, in which the cutter blade is configured to cut the medium by the cutter unit moving in a traveling direction along the guide rail, the cutter unit has a second pinion gear and a fourth roller which are in contact with the guide rail to be held to the guide rail, and the second pinion gear and the fourth roller are disposed so as to interpose the cutter blade therebetween in the traveling direction.

There is provided a cutting mechanism including: a cutter blade that can cut a medium, a cutter unit to which the cutter blade is attached, a first pinion gear that is rotatably attached to the cutter unit, and a rack gear that can mesh with the first pinion gear, in which the first pinion gear and the rack gear are configured with inclined teeth, and the cutter unit moves while the pinion gear is rotated in state of meshing the pinion gear and the rack gear.

There is provided a recording apparatus including: a recording unit that is configured to be capable of moving in a width direction of a medium and records an image on the medium; and a cutter unit that is configured to be connectable to the recording unit and cuts the medium by moving in the width direction, in which the recording unit has a first connection portion and a second connection portion for connecting with the cutter unit, and the cutter unit has a first engagement portion for engaging with the first connection portion and a second engagement portion for engaging with the second connection portion.

Provided is a slitter device capable of quickly supplying metal bands to a cutter stand and cutting same into strips with high speed and accuracy. The metal band slitter device comprises an unwinder that unwinds a metal band wound into a coil, a cutter stand that cuts the unwound metal band into narrow width strips, and a winder that winds the cut metal band into coils. The metal band slitter device is configured to comprise a tension adjustment unit on the winder side between the unwinder and the cutter stand that provides a constant tension to the metal band and a tension separating unit on the cutter stand side that separates the constant tension on the input side and tension on the output side.

Discussed is an apparatus for manufacturing an electrode for a secondary battery, an electrode for a secondary battery which is manufactured therethrough, and a secondary battery. The apparatus notches a portion of a non-coating portion of an electrode collector, which is not coated with an electrode active material, in an electrode sheet coated with the electrode active material on the electrode collector to manufacture an electrode tab. The apparatus includes a notching roll that rotates to notch the portion of the non-coating portion, wherein the notching roll includes: a notching cutter provided on a portion of the notching roll, which faces the non-coating portion to notch the electrode sheet; and a roll pad provided on a portion of the notching roll, which faces the electrode active material, the roll pad contacting the electrode sheet when the notching roll rotates to prevent the electrode sheet from being slipped.

A cutting device includes a cutter configured to cut a web including at least accumulated fibers and a ball screw mechanism configured to move the cutter in a transportation direction of the web, and the cutter, when the web is being transported, cuts the web in a direction intersecting the transportation direction while being moved in the transportation direction of the web by the ball screw mechanism.

A cutting device includes an upper cutting portion and a lower cutting portion. The upper cutting portion includes an upper head portion movable in a first and a second direction, an upper holder connected to the upper head portion, and an upper cutting wheel connected to the upper holder. The upper holder includes an upper body portion connected to the upper head portion, an upper cutting wheel fixing portion rotatable with respect to the upper body portion, and an upper magnetic portion disposed on sides of the upper cutting wheel fixing portion including a magnetic substance. The lower cutting portion includes a lower head portion movable in the first and the second direction, a lower holder connected to the lower head portion, a lower cutting wheel connected to the lower holder, and an upper holder rotation inducing portion connected to the lower head portion including a magnetic substance.
