There is provided a medium conveying device which includes a conveyance belt passed around a first roller and a second roller and configured to support and convey a medium on a supporting surface, and in which a controlling unit is able to execute first control to determine whether a first skewing direction and a second skewing direction are the same, the first skewing direction indicating whether, when the first roller and the second roller are caused to rotate in the first rotational direction, the conveyance belt moves toward one side or the other side in a width direction intersecting a moving direction of the conveyance belt, and the second skewing direction indicating whether, when the first roller and the second roller are caused to rotate in the second rotational direction, the conveyance belt moves toward the one side or the other side in the width direction.

When a veneer conveyed out by a discharging conveyor is a product veneer, a sorting apparatus is rotationally driven to pierce the product veneer with needle-like bodies by a guide member and a push-up member (a rolling bearing). When the veneer conveyed out by the discharging conveyor is a trash veneer, the sorting apparatus is rotationally driven so that the trash veneer is not pierced by the needle-like body. With this configuration, the progress of the abrasion of the needle-like bodies can be delayed as compared with the configuration in which the product veneer and the trash veneer are both pierced by the needle-like body. As a result, the time to replace the needle-like bodies can be extended, whereby the running cost can be reduced.

A packaging apparatus includes a controller configured to control operation of a first conveying unit, a second conveying unit, a first moving unit, and a second moving unit. When a film is loaded onto the first conveying unit and the second conveying unit, the controller causes a first clamp unit to clamp the film delivered from a delivering unit and causes a first feeder portion to convey the film. Simultaneously, while causing a second clamp unit to be released or the second clamp unit to intermittently clamp the film delivered from the delivering unit, the controller causes a second feeder portion to convey the film and also causes the second conveying unit to move in a direction separating from the first conveying unit and, when the second conveying unit reaches a predetermined position, causes the second clamp unit to clamp the film.

A folding apparatus for a continuous web for production of absorbent hygiene articles and intended to be folded into a “V” or “U” shape in first and second longitudinal portions along a folding line parallel to a feeding line. A folding section includes a contact unit extending along the feeding line and defining the folding line. First and second guides are positioned on opposite sides of the contact unit and respectively have first and second sliding surfaces. The first and second sliding surfaces extend in a helical fashion along the feeding line, each having a respective infeed section, where the web is not folded, and a respective outfeed section, positioned downstream of the respective infeed section according to a web feeding direction, where the web is folded in two and has the first portion and the second portion set at an angle to each other.

A recording device includes a recording unit capable of performing recording on a medium, a holding unit capable of holding a roll body around which the medium is wound, a transporting unit that transports the medium unwound from the roll body, a tension roller that, between the holding unit and the recording unit, comes into contact with a back surface of the medium and applies tension to the medium, and a blowing unit that blows air onto a front surface of the medium. The blowing unit blows the air towards the tension roller.

Included are a feeding shaft configured to hold a printing medium, a first transporting belt, a second transporting belt, a first driving roller on which the first transporting belt is wound, a second driving roller on which the second transporting belt is wound, a first driving unit configured to drive the first driving roller, a second driving unit configured to drive the second driving roller, a winding roller on which the printing medium is wound, a first winding roller bearing, a second winding roller bearing, a first load cell configured to detect a load exerted by the printing medium on the first winding roller bearing, a second load cell configured to detect a load exerted by the printing medium on the second winding roller bearing, and a control unit configured to control the first driving unit and the second driving unit based on detection results of the load cells.

There is provided a conveyance apparatus including: a holder configured to hold a roll body so that the roll body is rotatable around a first axis; a first conveyance member configured to convey a sheet pulled out of the roll body in a conveyance orientation; a support member arranged downstream of the first conveyance member in the conveyance orientation and has a support surface facing a first surface of the sheet; a recording head facing the support surface; and a first guide member which is arranged between the first conveyance member and the support member in the conveyance orientation, and which has first and second guide surfaces configured to guide first and second surfaces of the sheet. The first guide surface and the second guide surface are configured to guide the sheet so that the sheet has a curved shape in a cross-section orthogonal to the conveyance orientation.
