A continuous first web 351 fed in a first machine direction A in which absorbent member 302 of disposable diaper is to be obtained is coated on its outer surface with a hot melt adhesive agent 354, then guided and cut between upper and lower tool rolls 361, 362 to form the individual absorbent members 302. The absorbent member 302 is guided between the lower tool roll 362 and a guide roll 363 so that the adhesive agent 354 may be pressed against a peripheral surface of the guide roll 363 and then fed onto a reorienting roll 364. After having been reoriented on the reorienting roll 364, the absorbent member 302 is bonded to second web 352 fed in a second machine direction B by means of the adhesive agent 354. Preferably, both the upper tool roll 361 and the lower tool roll 362 have diameters smaller than a diameter of the reorienting roll 364. <；IMAGE>；
