    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 which extends at the transfer position. The first and second receiving rollers have outer diameters decreasing from proximal ends to distal ends and are disposed such that the distal ends are positioned on 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 holding region includes a first area bearing on at least part of one and at least part of the other of opposite skirt portions in a revolution direction of a holding pad, the first area extending along a first curve, when the holding pad is at a first revolution position. The holding region formed in the holding pad includes a second area bearing on at least part of one side portion and at least part of the other side portion in the revolution direction of the holding pad when the holding pad is at a second revolution position that extends along a second curve. The holding region includes a portion other than the first area and the second area that lies closer to a second rotational axis than the first curve and the second curve.

    Abstract: An absorbent article processing device includes a cutter roll and an anvil roll. The cutter roll includes a roll main body; a blade protruding in a radial direction in a first angular range of a part of a circumferential direction of the roll main body; a first bearer protruding in the radial direction in a second angular range of a part of the circumferential direction including at least the first angular range and being in contact with the anvil roll, and being cut out in an angular range excluding the second angular range at a first end portion in an axial direction of the roll main body; and a second bearer provided around the entire circumference or a part of the circumferential direction and being in contact with the anvil roll at the second end portion in an axial direction of the roll main body.

    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 another 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.

    Abstract: A transportation device includes a transportation-side holder that holds a roll. A roll mounting section, a sheet supply device including a supporter that holds the roll in a state where the sheet is continuously feedable, and an intermediate processing device that performs processing set in advance on the roll are disposed within a moving range of the transportation-side holder. A controller controls the transportation device such that the transportation-side holder holds the roll on the roll mounting section, and the roll held by the transportation-side holder is conveyed to the supporter of the sheet supply device through the intermediate processing device.

    Abstract: A roll conveyance device 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 such that the roll holding shaft is inserted into a core member of the roll; and a mounting section within a moving range of the roll holding shaft, the mounting section allowing the roll to be mounted in a state in which both axial ends of the core member of roll are open. The transportation device is configured to mount the roll on the mounting section, the roll holding shaft is to be pulled out from the core member of the roll mounted on the mounting section to a first side of an axial direction of the core member, and the roll holding shaft is to be inserted into the core member from a second side of the axial direction.

    Abstract: A holding region includes opposite skirt portions in a revolution direction of a holding pad each of which has at least opposite ends in a specific direction that extend along a first curve when the holding pad is at a first revolution position. 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.
