Patent ID: 8763669

Claim:
An apparatus for manufacturing a composite sheet of an absorbent article by joining a continuous body of an elastic strip member in a predetermined meander pattern to a continuous body of a sheet continuously transported in a transporting direction, the apparatus comprising: a first guide member configured to join a continuous body of a first elastic strip member to a continuous body of a sheet by feeding and surface-contacting the continuous body of the first elastic strip member to the continuous body of the sheet, via a first oscillating arm configured to oscillate in a direction intersecting the transporting direction with a first spindle portion as a swivel center; and a second guide member configured to join a continuous body of a second elastic strip member to the continuous body of the sheet by feeding and surface-contacting the continuous body of the second elastic strip member to the continuous body of the sheet, via a second oscillating arm configured to oscillate in a direction intersecting the transporting direction with a second spindle portion as a swivel center, wherein the first oscillating arm includes a first oscillating end side roller provided to an oscillating end side of the first oscillating arm and a first spindle portion side roller provided to the first spindle portion side, wherein the second oscillating arm includes a second oscillating end side roller provided to an oscillating end side of the second oscillating arm and a second spindle portion side roller provided to the second spindle portion side, wherein the apparatus is configured such that the continuous body of the first elastic strip member supplied toward the first spindle portion side roller through a first supply route is subsequently, put around an outer circumferential face of the first spindle portion side roller and an outer circumferential face of the first oscillating end side roller, and, after being reversed in a travel direction with the first oscillating end side roller, is placed on the continuous body of the sheet and joined thereon, wherein the apparatus is configured such that the continuous body of the second elastic strip member supplied toward the second spindle portion side roller through a second supply route is subsequently put around an outer circumferential face of the second spindle portion side roller and an outer circumferential face of the second oscillating end side roller, and, after being reversed in the travel direction with the second oscillating end side roller, is placed on the continuous body of the sheet and joined thereon, wherein the apparatus is configured such that a first placing position where the continuous body of the first elastic strip member is to be placed on the continuous body of the sheet with the first oscillating arm and a second placing position where the continuous body of the second elastic strip member is to be placed on the continuous body of the sheet with the second oscillating arm are different from each other in the transporting direction.
