A method for producing a wearing article includes conveying a front-abdominal-portion forming strip and a rear-dorsal-portion forming strip; dividing the front-abdominal-portion forming strip being conveyed, along a dividing line parallel to a width direction thereof; holding a relative positional relationship between two segments of the front-abdominal-portion forming strip on both sides of the dividing line; within a period of implementation of the step of holding, detachably attaching a first attaching-detaching member to the front-abdominal-portion forming strip in such a manner as to cover the dividing line, thereby restricting a relative displacement between the segments of the front-abdominal-portion forming strip on both sides of the dividing line; joining the front-abdominal-portion forming strip and a front region of a crotch portion together; and joining the rear-dorsal-portion forming strip and a rear region of the crotch portion together.

A method for controlling a conveyance speed of a sheet comprises the steps of: setting a reference rotation angle; rotationally driving a drive motor (8) and a rotary cutter (15); detecting a marker (2a) of a backsheet (2); detecting a rotation angle of a rotary blade of a cutting member when the marker (2a) is detected; ascertaining an angular difference between the detected rotation angle and the reference rotation angle; and controlling rotational driving of the drive motor (8) to reduce the angular difference.

The present welding device is a device for welding webs W, the device including: a drum 20 and an anvil 21 rotating about an axis; a transfer section 22 provided on a periphery of the drum 20 to rotate together with the drum 20; a horn 11 which, together with the anvil 21, applies a vibration energy to a layered portion of the webs; a cutter 30 which comes into contact with the anvil 21 to cut the webs; a sensor 40 for measuring a distance between the anvil 21 and the horn 11; and a control section for controlling a relative positions of the anvil 21 and the horn 11 based on the measured distance between the anvil 21 and the horn 11 as measured by the sensor. While the horn 11, together with the anvil 21, applies the violation energy to the webs W, the cutting of the webs W by the cutter 30 is not performed.

An article including: an absorbent body including two liquid-permeable non-woven fabric sheets bonded together at bonded portions in a predetermined pattern, and a plurality of granular particles placed therebetween separately in each of a plurality of placement areas partitioned from one another in the predetermined pattern; and a non-liquid-permeable back sheet placed on a non-skin-contact surface of the absorbent body, wherein: a liquid-permeable sheet is placed so as to cover an entire surface of the non-woven fabric sheet on a skin-contact surface side; and an easily-breakable portion capable of being broken when the granular particles absorb a bodily fluid to swell is formed in placement areas on at least one non-woven fabric sheet.
摘要:
A method for manufacturing a disposable worn article, including: severing a continuous web W along a cut-off line L1 having a predetermined wave shape, dividing the continuous web W into a first and second divided webs W1, W2; allowing the first and second divided webs W1, W2 to cross each other in a width direction X so as to reverse positions of the first and second divided webs W1, W2 in the width direction X; reversing the second divided web W2 by twisting the second divided web W2 by 180°; rotating a second side panel which is cut off from the second divided web W2 by 180°, thereby producing a second side panel PR in line symmetry with a first side panel PL which is cut off from the first divided web W1; and placing and fastening the side panels PL, PR to the side portions of the body 20.
