Method and device for producing disposable worn article

A device for producing a disposable worn article, in which a pair of panels are fastened to a body portion at the same position in a longitudinal direction thereof and in left and right opposite side portions in a girth direction thereof, the device comprising:

• a cutter for successively severing tip portions of a continuous web in a flow direction, the continuous web being continuous in the flow direction, along a virtual severing line extending in a width direction perpendicular to the flow direction, thereby successively producing a plurality of panels;
• an interval-increasing drum for increasing an interval in the width direction between a pair of panels, adjacent to each other in the flow direction, of the plurality of panels;
• and
• a phase wheel for receiving the panels by first and second rollers at first and second receiving positions, which are separated from each other in the flow direction, wherein the first and second rollers are placed so that a first axial line of the first roller for receiving and holding one of the pair of panels separated from each other in the width direction and a second axial line of the second roller for receiving and holding the other one of the pair of panels are placed offset from each other in the flow direction of the panels, and for placing the panels, from the first and second rollers at first and second hand-over positions which are separated from each other in the flow direction, onto the opposite side portions of the body portion at the same position in the longitudinal direction of the body portion.

A method for producing a disposable worn article, in which a pair of panels are fastened to a body portion in left and right opposite side portions in a girth direction thereof, the method comprising:

• a severing step of successively severing tip portions of a continuous web in a flow direction, the continuous web being continuous in the flow direction, along a virtual severing line extending in a width direction perpendicular to the flow direction, thereby successively producing a plurality of panels;
• a first re-pitching step of increasing an interval in the flow direction between the plurality of panels;
• an interval-increasing step of, after the first re-pitching step, increasing an interval in the width direction between a pair of panels, adjacent to each other, of the plurality of panels;
• and
• a placement step of, after the interval-increasing step, placing the pair of panels in the opposite side portions of the body portion.

• a first re-pitching drum for increasing an interval in the flow direction between the plurality of panels;
• an interval-increasing drum, placed downstream of the first re-pitching drum, for increasing an interval in the width direction between a pair of panels, adjacent to each other, of the plurality of panels;
• and
• a phase wheel, placed downstream of the interval-increasing drum, for placing the pair of panels in the opposite side portions of the body portion.
