Above the gap between the inner ends of 85b, a pair of pressers 42 with their proximal ends attached at a required distance in the lateral direction are attached to the rotating shaft 4B.
It is supported by The first continuous absorbent material 2B guided to the first folding guide 8z is moved forward while straddling the gap between the upper wall portions 85a and 85b and positioned between these and the supporting member axis, until the non-folding portion 81 is moved forward. By pressing the non-folding portion 81 with its tip while rotating the presser 42 once while coming under the suppressor 4z, the non-folding portion 81 is forcibly pushed into the lower surface of the upper wall portions 85a, 85b. , and while moving the first continuous absorbent material 2B forward with the folded part 80 supported on the upper surfaces of the upper walls 85a and 85b, first, one side of the folded part 80 is gradually moved by the inner end of the upper wall part 85a. The supporting member 84 is made to stand up and bent over the upper surface of the support member 84, and then the other side portion is similarly raised up gradually by the inner end of the upper wall portion 85b and bent over the upper surface of the bent side (11th (See figure) As shown in 4111
