Abstract: In a production apparatus, a pass line for conveying a film is formed in parts of both belts wound on common rolls and in contact with each other across the film, a discharge port of a discharger is so provided that the molten resin reaches one first roll, out of a group of first rolls, on a side upstream of the pass line, and the common rolls include a cooling roll for cooling and solidifying the molten resin discharged from the discharge port and having reached the first roll.

Abstract: A manufacturing method including a first conveying step of conveying the sheet in a lateral or oblique lateral direction along a sheet pass line below the discharge port; a receiving step of receiving a tip part of the film raw material with the sheet on the sheet pass line, the tip part being discharged and hanging down from the discharge port; a second conveying step of conveying the sheet and the film raw material after the tip part overlaps the sheet on the sheet pass line, the second conveying step conveying the sheet and the film raw material in a mutually overlapping state along the sheet pass line; and an introducing step of introducing the sheet and the film raw material in the mutually overlapping state to the joining part from the sheet pass line.

Abstract: An elastic resin material having a thermoplastic elastic resin as a main component is heated and melted, and the elastic resin material is discharged in a film or a linear shape from a discharge mechanism to form a film-shape or a linear-shape intermediate product. At a temperature above the temperature region at which the elastic resin material elastically deforms, extending is performed until the thickness or width of the film-shape intermediate product or the thickness of the linear-shape intermediate product assumes a prescribed value; with a cooling roller, the intermediate product is cooled to the temperature region at which the elastic resin material elastically deforms, and the intermediate product is hardened, forming a film-shape or linear-shape elastic member. The elastic member is stretched with a stretch roller to a prescribed stretching ratio, and the stretched elastic member is laminated on and bonded to a first base material sheet.

Abstract: A transport device includes a plurality of pads that hold and transport a workpiece while a peripheral speed is changed. The transport device further includes: a rotation shaft having an axial line serving as a rotation center; a rotation body that rotates around the rotation shaft; the plurality of pads that hold and transport the workpiece while the peripheral speed is changed with respect to the rotation shaft; transmission mechanisms that change a speed of each pad; and a motor provided for each pad and including an output shaft that drives each of the transmission mechanisms. In the transport device, each motor is attached to the rotation body, and is arranged around the axial line of the rotation shaft such that the output shafts are parallel to each other in a direction in which the axial line of the rotation shaft extends.

Abstract: A distribution step of distributing a powder onto a first sheet, a first closing step of periodically closing a distribution port by a first opening-closing device, and a second closing step of periodically closing the distribution port by a second opening-closing device in the same cycle period as that of the first opening-closing device and at a timing later than that of the first opening-closing device, and moving the second opening-closing device such that it extends from an upstream-side edge of the first opening-closing device toward an upstream side of a movement direction, during a time period during which the upstream-side edge of the first opening-closing device overlaps the distribution port, are implemented, and further a timing setting step of setting a difference between timings at which the first and second opening-closing device overlap the distribution port, respectively.

Abstract: Using a conveyance roller having an outer peripheral surface which is capable of conveying two sheets with an elastic element sandwiched therebetween, in a longitudinal direction of the sheets, and formed with a convex section; and a clamping and pressing device, the sheets with the elastic element sandwiched therebetween are ultrasonic-welded together under pressing. The convex section is formed in a shape extending along a line intersecting a conveyance direction of the conveyance roller, and the convex section is provided with a plurality of grooves at positions spaced apart from each other in a longitudinal direction thereof, wherein each of the grooves extends in the conveyance direction of the conveyance roller to allow a portion of the sheets on which the elastic element is disposed, to be inserted therein.
