Abstract: When a remaining amount of a sheet on one original sheet roll is equal to or less than a predetermined remaining amount, a pair of holding pads is brought into a first posture where holding surfaces are opened, and the holding surface of one holding pad is pressed to a joining end portion from the outside of the original sheet roll in a radial direction of the other original sheet roll. Further, the holding pad is moved such that the joining end portion is separated toward the outside of the original sheet roll in the radial direction. Further, the posture of the pair of holding pads is changed into a second posture where the holding surfaces approach each other, and the joining end portion is conveyed to a joining part in a state where the joining end portion is sandwiched between the holding surfaces of the pair of holding pads.

The holding region includes a second area bearing on at least part of one side portion and at least part of the other side portion in a revolution direction of the holding pad when the holding pad is at a second revolution position that extends along a second curve. A delivery side holding region includes opposite side portions in the specific direction each of which has at least opposite ends in a rotational direction, each end being formed with a first recess. The first recess having a bottom surface that extends along an arc of the first curve.

Abstract: A sheet-feeding system includes a holding part which holds an end portion of a sheet, a nozzle part for discharging an adhesive agent for joining sheets to each other, and a nozzle moving unit which supports the nozzle part such that the nozzle part is made movable within a region including both temporarily holding parts, in which when a sheet joining condition is established where a remaining amount of the sheet on one original sheet roll becomes equal to or below a predetermined remaining amount, an end portion of the sheet on the other original sheet roll is conveyed to the temporarily holding part by the holding part and, thereafter, the nozzle part is moved to the temporarily holding part, and the adhesive agent is discharged to the end portion of the sheet from the nozzle part.

Abstract: The present invention includes: a transportation device including a roll holding shaft extending in a predetermined direction from a distal section of an arm to hold a roll in a state of being inserted into a core member of the roll; and a mounting section disposed within a moving range of the roll holding shaft, the mounting section allowing the roll to be mounted in a state where both ends of an axial direction of the core member of roll are open. The transportation device mounts the roll on the mounting section, the roll holding shaft is pulled out from the core member of the roll mounted on the mounting section to one side of an axial direction of the core member, and the roll holding shaft pulled out from the core member is inserted into the core member from the other side of the axial direction.

Abstract: A transport unit includes: a transporting device that turns a pad 90 degrees while the pad rotates from a receiving position to a transfer position; and first and second receiving rollers that sandwich a sheet and an absorbent body between a holding surface and the respective receiving rollers at the transfer position. The holding surface includes first and second sloped surfaces that are aligned along a pad rotating shaft extends at the transfer position. The first and second receiving rollers have outer diameters decreasing from the proximal ends to the distal ends and are disposed such that distal ends are positioned on the sides of first and second ends of the holding surface, respectively. The first and second receiving rollers are disposed so as to sandwich the sheet and the absorbent body between the first and second sloped surfaces and the first and second receiving rollers, respectively.

Abstract: A sheet delivery system includes: a joining unit which joins, to an intermediate section of a sheet being delivered from a delivery-side original material roll, an end section of a sheet W of a standby-side original material roll; and an operation robot which retrieves the end section of the sheet from the standby-side original material roll and which conveys the end section of the sheet to the joining unit. The sheet delivery system sets, in advance, a sheet retrieval position at which the sheet is retrieved from each of the original material rolls, for each of the original material rolls. The operation robot is configured to convey the end section of the sheet from each of the sheet retrieval positions to the joining unit.

Abstract: A disposable wearable article includes an absorptive body in which an absorber is disposed between a top sheet and a back sheet; flap parts that are put on one of a front part and back part of the absorptive body and extend to the both sides in the around-torso direction; and fastener members that are each provided on the flap part at a distance from a tip end of the flap part in the around-torso direction and are attachably and detachably joined to an opposing part put on the absorptive main body. Each flap part is formed from thermoplastic nonwoven fabric and has, in an extending part between the tip end of the flap part and the fastener member, a thermally-fused part at which the nonwoven fabric is thermally fused and bending rigidity of the nonwoven fabric is increased.

Abstract: A sheet conveying device includes: a holding mechanism configured to hold suction members; and a driving device including a rotary shaft which is rotatable about a second axis parallel to the first axis and a connecting mechanism configured to connect the rotary shaft and suction members to each other; and a support mechanism configured to support the holding mechanism and the drive device. The connecting mechanism is connected to the suction members in a state where the suction members are movable in a radial direction of the circle about the first axis. The support mechanism supports the holding mechanism and the drive device such that the holding mechanism and the drive device are relatively movable from each other in a direction orthogonal to the first axis.
