A wrinkle smoothing device for a composite body of a continuous sheet related to an absorbent article includes a first belt that moves along a first travel path while retaining the central portion of the continuous sheet, and second and third belts that move along second and third travel paths while retaining side portions of the continuous sheet. The second and third travel path are inclined from the first travel path such that a downstream side is more spaced apart from the first travel path than an upstream side. The second and third belts retain side portions of the continuous sheet while relatively sliding in the width direction of the continuous sheet.

A sheet manufacturing apparatus includes: a first transport unit that causes a first transport belt to circle around so as to transport a web; and a second transport unit that is disposed with a part thereof shifted from the first transport unit toward the downstream side in a transport direction of the web, sucks the web in a direction in which the web is spaced from the first transport belt, and transports the web. The second transport unit includes a suction chamber which is positioned on an inner side of a second transport belt circling around and of which an inner space is sucked by a suction unit such that the web is adsorbed onto the second transport belt. The suction unit is positioned on the outer side of the second transport belt in a direction orthogonal to the transport direction of the web along the surface of the web.

A sheet manufacturing apparatus includes a first transport unit, a second transport belt disposed with a part thereof shifted from the first transport unit toward the downstream side in a transport direction of the web, a suction chamber positioned in an inner side of the second transport belt and configured to create suction inside the suction chamber to suck the web onto the second transport belt, and a current plate positioned inside of the suction chamber to adjust an air current. The current plate has a plurality of holes, and is spaced apart from a surface of the second transport belt such that the air current is diffused between the current plate and the surface of the second transport belt to achieve a uniform suction force in a width direction of the second transport belt.

A conveying apparatus for a separator of an electrical device alternately laminates a first electrode and a second electrode of different polarity from the first electrode, with a separator interposed therebetween to form a laminated body for conveyance. The separator includes a melt material representing a substrate and a heat-resistant material laminated on one surface of the melt material and having a higher melting point than the melt material. The separator conveying apparatus includes a drive member which makes contact with the separator and conveys the separator; and a pressure member which, while urging the drive member via the separator, is driven by the drive member. The drive member makes contact with the melt material portion of the separator. With this separator conveying apparatus, it is possible to maintain constant feed size or dimension of the separator assembly.

The present invention provides methods and systems for applying a second-piece material to a paperboard cutout that includes a conveyor belt used for transporting the paperboard cutouts, a vacuum belt, at least two metering rolls, a first roller and second roller in a spaced apart and planar relationship, a nip roller positioned adjacent the second roller, and a cutting device. The vacuum belt proceeds over the first roller and the at least two metering rolls meter the second-piece material thereon, the vacuum belt proceeds through a valley between the first roller and second roller, at a predetermined time, the nip roller continues to pull the vacuum belt and the metering rolls pull back slightly and pulling the second-piece material taught and causing the second-piece material to contact the cutting device, and thus cutting the second-piece material.

A sheet manufacturing apparatus 1 includes an accumulation section 50 that forms a web W; a transport belt 621 that comes into contact with one surface of the web W to hold the web W and transports the web W; a suction section 200 that is provided above the transport belt 621 to cause the web W to be adsorbed to the transport belt 621; and a sheet forming section 70 that forms the sheet with the web W, in which the suction section 200 has a first duct 210, a second duct 220 provided downstream of the first duct 210 in the transport direction, and a third duct 230 provided downstream of the second duct 220 in the transport direction, and a plurality of third suction holes 239a and 239b are provided in a suction region 233 of the third duct 230, the suction region 233 includes a first region 233a and a second region 233b located downstream of the first region 233a in the transport direction, and the number of the third suction holes 239b provided in the second region 233b is smaller than the number of the third suction holes 239a provided in the first region 233a.
