The first elastic strip member supplied toward a first spindle portion side roller is subsequently put around an outer circumferential face of the first spindle portion side roller and an outer circumferential face of a first oscillating end side roller. The second elastic strip member supplied toward the second spindle portion side roller of a second oscillating arm is subsequently put around an outer circumferential face of a second spindle portion side roller and an outer circumferential face of the second oscillating end side roller of the second oscillating arm. | 04-19-2012 |
20120222798 | METHOD AND APPARATUS FOR MANUFACTURING A COMPOSITE SHEET - In a method of manufacturing a stretchable composite sheet, the first continuous sheet is stretched while being transported from a first nip area to a second nip area. The first continuous sheet is either a sheet in which stretchability has already been developed or a sheet in which stretchability has yet to be developed. An opening is formed in the first continuous sheet intermittently in the transport direction, while transporting the first continuous sheet from the second nip area to a third nip area after the stretching operation. A second continuous sheet having a lower stretchability than the first continuous sheet is overlapped and adhered to the first continuous sheet in the third nip area. | 09-06-2012 |
20130031813 | METHOD AND APPARATUS FOR PRODUCING A STRETCHABLE SHEET - In a method of producing a stretchable sheet using a pair of gear rolls each having a plurality of teeth arranged on a circumference thereof, a raw sheet is drawn by passing the raw sheet through a gap between the pair of gear rolls. The raw sheet contains a plurality of types of fibers, and has a plurality of recessed sections formed by pressing. The recessed sections are formed collinearly at least along the drawing direction at a predetermined formation pitch in the drawing direction. An arrangement pitch of the teeth in the drawing direction is greater than the formation pitch and smaller than twice the formation pitch. | 02-07-2013 |
20130299096 | MANUFACTURING METHOD AND MANUFACTURING APPARATUS OF COMPOSITE SHEET OF ABSORBENT ARTICLE - A method of manufacturing a composite sheet includes joining a first elastic strip member to a sheet by feeding and surface-contacting the first elastic strip member to a continuous body of the sheet; and joining a second elastic strip member to the sheet by feeding and surface-contacting the second elastic strip member to the continuous body. The first elastic strip member supplied toward a first spindle portion side roller is subsequently put around an outer circumferential face of the first spindle portion side roller and an outer circumferential face of a first oscillating end side roller. The second elastic strip member supplied toward the second spindle portion side roller of a second oscillating arm is subsequently put around an outer circumferential face of a second spindle portion side roller and an outer circumferential face of the second oscillating end side roller of the second oscillating arm. | 11-14-2013 |
20130344286 | NONWOVEN FABRIC, AND METHOD FOR PRODUCING NONWOVEN FABRIC - A nonwoven fabric comprising extendable fiber and elastic fiber, wherein the nonwoven fabric comprises a first side having a plurality of protrusions and a plurality of recesses and a second side on the side opposite the first side, the proportion of extendable fiber in the protrusions on the first side is higher than the proportion of extendable fiber in the recesses on the first side, and the nonwoven fabric is coated with a hydrophilic agent, or the extendable fiber and elastic fiber comprise a hydrophilic agent, the nonwoven fabric has a water absorbing property represented by a water absorption height of at least 10 mm in a water absorption test, and a quick-drying property represented by a transpiration rate of at least 20 mass % in a transpiration test. | 12-26-2013 |
20140102618 | METHOD FOR MANUFACTURING STRETCH SHEET - A method for manufacturing a stretch sheet draw a nonwoven fabric conveyed in a continuous state by teeth formed on an outer circumferential surface of a pair of rotating rollers by passing the nonwoven fabric through a gap between the rotating rollers meshing with each of the teeth. The method includes a step of joining a first end of the first nonwoven fabric roll and a second end of the other nonwoven fabric roll through a joint portion. The joint portion is arranged intermittently in a cross direction that crosses the conveyance direction. | 04-17-2014 |
20140234575 | LAYERED NONWOVEN FABRIC, AND METHOD FOR PRODUCING LAYERED NONWOVEN FABRIC - A layered nonwoven fabric with excellent feel on the skin and liquid permeability, and a method for producing the layered nonwoven fabric. The layered nonwoven fabric includes an upper layer consisting of a first nonwoven fabric and a lower layer consisting of a second nonwoven fabric. The layered nonwoven fabric has a first surface on the first nonwoven fabric side with a plurality of protrusions and recesses and a second surface on the second nonwoven fabric side. The protrusions on the first surface have a higher basis weight than the recesses on the first surface, and the protrusions on the first surface have a lower fiber density than the recesses on the first surface. | 08-21-2014 |
20140302286 | COMPOSITE STRETCH MATERIAL AND MANUFACTURING PROCESS THEREFOR - A composite stretch material which is composed of a first nonwoven fabric sheet part and a second nonwoven fabric sheet part and elastic members disposed therebetween. In each nonwoven fabric sheet part, concave parts and convex parts are formed in the thickness direction. The concave and convex parts formed alternately repeatedly in a first direction define convex-concave rows. The convex-concave rows are separated from each other by non-shaped regions which contain neither concave parts nor convex parts and which extend along the first direction. The non-shaped regions are joined to each other with the elastic member therebetween. The convex parts of the first nonwoven fabric sheet part enter respectively into the concave parts of the second nonwoven fabric sheet part, while the convex parts of the second nonwoven fabric sheet enter respectively into the concave parts of the first nonwoven fabric sheet part. | 10-09-2014 |
20150067996 | METHOD AND DEVICE FOR RECOVERING BULK OF NONWOVEN FABRIC - A device and method for excellent recovery of bulk in nonwoven fabric. While nonwoven fabric is transported so as to enter a heating chamber via an entry opening and, after progressing within the heating chamber, exit the heating chamber via an exit opening, heated air is supplied at a speed higher than the transport speed for the unwoven fabric so as to enter the heating chamber via the entry opening and after progressing within the heating chamber while contacting the nonwoven fabric, exit the heating chamber via the exit opening. | 03-12-2015 |
