Abstract: The present layered stretchable sheet includes: a plurality of attachment portions at which a pair of non-woven fabrics and a film are thermally bonded together, wherein each one of the attachment portions includes at least one thermal bonding area where the pair of non-woven fabrics and the film are thermally bonded together; at least one boundary line that defines the thermal bonding area; a first vent that is defined by a first opening of the film appearing in a stretched state of the film along the boundary line and that exerts air permeability; and a second vent that is defined by a second opening where a part of the film is absent, the second opening being adjacent to the thermal bonding area and being delimited by the boundary line, wherein the second vent exerts air permeability both in the stretched state and in a non-stretched state.

Abstract: The transport method includes a speed varying step of varying speed of a first holding portion between a receiving position and a predetermined relay position by means of a speed change mechanism; a control step of controlling speed of a servo motor for driving rotation of second holding portions, such that speed of the second holding portions becomes a receiving speed at which the second holding portions is able to receive the absorbent body from the first holding portion at the relay position and becomes a predetermined transfer speed at a transfer position, and such that the second holding portions arrive at the relay position and at the transfer position at a predetermined cycle; and a speed changing step of changing the transfer speed while the cycle is maintained.

Abstract: An elastic member drive device includes: a drive shaft 12a that allows a plurality of pulleys 21, 31 and 41 to be removably attached as being coaxially aligned in the rotation center axis direction; transmission belts 23, 33 and 43 that are respectively wound around pulleys 21, 31 and 41; and a driver portion 12 that controls regular and reverse rotations of the drive shaft 12a, wherein the guides 25, 35 and 45 are respectively fixed to the transmission belts 23, 33 and 43. A feed amount difference in the web width direction is allowed to be set for each of the guides 25, 35 and 45 by determining a pulley diameter ratio among the pulleys 21, 31 and 41.

Abstract: In arranging a plurality of elastic members continuously fed in an expanded state on one surface of a continuously fed web at intervals in the web width direction, it is to achieve free and easy setting of the intervals among the elastic members. The present invention includes: a drive shaft 12a that allows a plurality of pulleys 21, 31 and 41 to be removably attached as being coaxially aligned in the rotation center axis direction; transmission belts 23, 33 and 43 that are respectively wound around pulleys 21, 31 and 41; and a driver portion 12 that controls regular and reverse rotations of the drive shaft 12a, wherein the guides 25, 35 and 45 are respectively fixed to the transmission belts 23, 33 and 43; and a feed amount difference in the web width direction is allowed to be set for each of the guides 25, 35 and 45 by determining a pulley diameter ratio among the pulleys 21, 31 and 41.

Abstract: The production method for producing an article, comprises the step of rotating a rotating member so as to machine a semi-finished product with a machining section included in the rotating member. A circumferential velocity of the rotating member can be changed according to a size of the semi-finished product during one cycle in which the semi-finished product is machined.

Abstract: An absorbent article (1) includes a cuff (30) and a liquid-holding absorbent (5). The cuff (30) is provided on a surface of a sheet (3) covering the liquid-holding absorbent (5). The cuff (30) is obtained by folding the sheet, which faces a surface of a body of a wearer, and folding back the sheet so as to form a two-folded shape. An adhesion section (37) for keeping the two-folded shape of the cuff is provided at least near a base portion of the cuff.
