摘要： A manufacturing apparatus for manufacturing an absorbent article, the manufacturing apparatus including: an upstream transport mechanism and a downstream transport mechanism that transports a stretchable sheet-like member along a transporting direction, the stretchable sheet-like member continuing along the transporting direction; an extension-ratio adjustment mechanism that is located between the upstream transport mechanism and the downstream transport mechanism, and that adjusts an extension ratio at which the stretchable sheet-like member extends in the transporting direction; and a processing apparatus that performs the certain process to the stretchable sheet-like member that is being transported by the downstream transport mechanism. When the upstream transport mechanism transports a first stretchable sheet-like member in which parts to be the absorbent article are lined up at a first pitch in the transporting direction, the extension-ratio adjustment mechanism adjusts an extension ratio of the first stretchable sheet-like member so that the parts to be the absorbent article are lined up at a predetermined pitch. When the upstream transport mechanism transports a second stretchable sheet-like member in which the parts to be the absorbent article are lined up at a second pitch in the transporting direction, the second pitch being different from the first pitch, the extension-ratio adjustment mechanism adjusts an extension ratio of the second stretchable sheet-like member so that the parts to be the absorbent article are lined up at the predetermined pitch.

摘要： An ultrasonic processing system adapted to subject a web running in a machine direction to ultrasonic processing includes a first mechanical element defined by one of an ultrasonic horn and an anvil and a second mechanical element defined by a remainder. The web placed on an outer peripheral surface of a rotary drum moves conforming to the drum in a machine direction. The first mechanical element is provided on the inner side of the drum and the second mechanical element is provided on the outer side of the drum. The first and second mechanical elements repeat a step of forward movement and a step of backward movement in a direction intersecting the machine direction across the web. In both steps, the first and second mechanical elements come in close contact with each other by the intermediary of the web and thereby subject the web to the ultrasonic processing.

摘要： An animal litter box contains: a liquid-permeable top-surface sheet; a liquid-impermeable back-surface sheet disposed on one side of the top-surface sheet in a thickness direction of the animal absorbent sheet; and an absorbent body disposed between the top-surface sheet and the back-surface sheet. The absorbent body includes a first absorbent layer and a second absorbent layer disposed closer to one side of the animal absorbent sheet in the thickness direction with respect to the first absorbent layer. The first absorbent layer contains a superabsorbent polymer and an antibacterial agent. The second absorbent layer is formed of a mixture of a liquid-permeable fiber and the superabsorbent polymer. A density of the antibacterial agent is higher on one side of the first absorbent layer than on the other side of the first absorbent layer in the thickness direction.

摘要： An absorbent sheet for a pet toilet is provided. The pet toilet includes: a sheet accommodating portion that accommodates the absorbent sheet in a space surrounded by a bottom portion and side walls standing from the bottom portion; and an excretion receiving portion that receives excretions above the sheet accommodating portion and guides the excretions to the sheet accommodating portion. The absorbent sheet includes: a topsheet on a top side of the absorbent sheet and that includes fibers; a backsheet on a back side of the absorbent sheet; an absorber between the topsheet and the backsheet; a central region in which the absorber is disposed in plan view; and side regions that extend outside the central region and in which at least the topsheet is disposed.

摘要： A linear-motor type transport device for transporting material for an absorbent article includes: a shaft portion that has an axial direction, a radial direction, and a circumferential direction; a pair of guide portions that is disposed on the shaft portion with a predetermined axial-direction space between the guide portions and that forms an orbital transport path that extends along the circumferential direction; a mobile unit that moves on the transport path along the guide portions while supporting a transport head rotatably about a rotation axis; a cam mechanism that rotates the transport head about the rotation axis through a predetermined angle when the mobile unit is moved on the transport path; and a controller that moves the mobile unit by supplying currents to conductors and generating a propulsive force between one of the conductors and a magnet that is disposed on the mobile unit.

摘要： The present invention provides a belt-shaped body that is worn around the torso of an animal and that detachably fixes a crotch member disposed on the crotch of the animal, wherein the crotch member does not easily detach or become displaced from the suitable position. This belt-shaped body (1) has, in plan view in a spread-out state, a longitudinal direction (L) corresponding to the direction encircling the torso of an animal, and a width direction (W) corresponding to the front-back direction of the animal, and also has an abdomen-corresponding region (AC) corresponding to the abdomen of the animal and including an axis line (CW) that extends in the width direction (W) and is located in the center relative to the longitudinal direction (L), and two back-corresponding regions (A1, A2) that correspond to the back of the animal and that are located in both portions adjacent to the abdomen-corresponding region (AC) in the longitudinal direction (L). At least in the abdomen-corresponding region (AC), the rigidity in the width direction (W) is higher than the rigidity in the longitudinal direction (L).
