Abstract
A method and apparatus (20) for making an absorbent article can include a delivering of a first contoured web-strip (30a) from a first production supply (38) of contoured web-strip material, with the first contoured web-strip (30a) presenting a primary production sequence of side edge contours during its delivery. At least a second contoured web-strip (30b) can be delivered from a second production supply (40) of the contoured web-strip material, with the second contoured web-strip (30b) also presenting the primary production sequence of side edge contours during its delivery. In a particular aspect, the first and second contoured web-strips (30a and 30b) have been produced from a web (22) of absorbent material which has been divided to provided at least two web-strips (30) having a substantially nested configuration. In another aspect, the first web-strip (30a) provides a first orientation which presents a first sequence of side edge contours; and the second web-strip (30b) provides a longitudinally-reversed orientation which presents a different, substantially reversed sequence of side edge contours. In an additional aspect, the web-strips (30) have been separately stored to prov…
