To provide a method for successfully covering an absorbent core with a core wrap sheet without generating wrinkles on the core wrap sheet and without causing falling or losing a shape of a forming material of the absorbent core.SOLUTION: An absorbent core 50 has lengths in a perpendicular direction (CD) that are different in a delivery direction (MD), and has a narrowest width part 50N where the length in the CD is shortest. With a pair of virtual straight lines VL, VL which pass through both ends of the CD of the narrowest width part 50N and extend in the MD direction as boundaries, a delivery surface (a conveyor belt 42) moving in arrangement regions of a folding guide 441 is sectioned into a central area 45 sandwiched between the pair of virtual lines VL, VL and a lateral area 46 positioned on both sides of the CD with the central area 45 in between. Suction force 46V in the lateral area 46 is set to be lower than suction force 45V in the central area 45.SELECTED DRAWING: Figure 6 【課題】コアラップシートに皺を生じさせず、且つ吸収性コアの形成材料の脱落や型崩れを生じせずに、コアラップシートによって吸収性コアを首尾よく被覆し得る方法を提供すること。【解決手段】吸収性コア５０は、搬送直交方向（ＣＤ）の長さが搬送方向（ＭＤ）に沿って異なっており、ＣＤの長さが最小の部分である最幅狭部５０Ｎを有する。最幅狭部５０ＮのＣＤの両端を通ってＭＤに延びる一対の仮想直線ＶＬ，ＶＬを境界として、折り返しガイド４４１の配置領域を移動する搬送面（コンベアベルト４２）を、該一対の仮想直線ＶＬ，ＶＬに挟まれた中央域４５と、該中央域４５を挟んでＣＤの両側に位置する側方域４６とに区分し、側方域４６の吸引力４６Ｖを中央域４５の吸引力４５Ｖに比べて低くする。【選択図】図６
