Manufacturing method for absorbent products and manufacturing device for absorbent products

Abstract

Provided is a manufacturing method for absorbent products that has a process for forming a pair of fold-over parts (50a, 50b), which can be folded over in the direction of conveyance of a flap line and in the direction opposite said conveyance direction, on portions of areas (30A) that constitute a single flap in connected flaps (130) that are continuously conveyed on the flap line, a process wherein fastening members (40a, 40b), which are fastenable to prescribed areas, are placed on the pair of fold-over parts (50a, 50b), and a process wherein connected flaps (130) are connected with connected front torso-surrounding members or back torso-surrounding members (120a) or (120b) so that each area (30A) that constitutes a single flap, corresponds to areas (20A, 20B), that constitute a singleabsorbent product in connected front torso-surrounding members or back torso-surrounding members (120a) or (120b).

Description

technical field [0001] The present invention relates to an absorbent article manufacturing method and an absorbent article manufacturing apparatus including a front waist member, a rear waist member, and a crotch member connecting the front waist member and the rear waist member. Background technique [0002] In general, an unfolded diaper needs to be provided with side panels protruding outward from the absorber main body in order to facilitate wearing on the body. [0003] There is known a manufacturing method in which side panels are provided in this unfolded diaper by the following steps (for example, Patent Document 1). [0004] (1) On the continuum (continuous belt part) of the flap, between each first belt surface buckle arranged along the CD direction and each second belt surface buckle along the CD direction (with The direction intersecting the conveying direction) is the process of forming a shearable line. [0005] (2) The process of arrange|positioning the cont...

AI Technical Summary

Problems solved by technology

Therefore, when the breaking strength of the shearable thread is increased in order not to cut the shearable thread on the flap production line, there is a problem that it is difficult for the user of the diaper to cut the shearable thread.

[0008] In addition, in the manufacturing method of the above-mentioned unfolded diaper, when the strength of the cuttable line is weakened so that the user of the manufactured diaper can easily cut off the cutable line, it is transported on the flap production line. In the process of the continuous body of the airfoil, the shearable line may be cut sometimes, and the continuous body of the airfoil (continuous belt part) cannot be continuously conveyed on the airfoil production line, or in order to continuously convey the airfoil on the airfoil production line The continuum (continuous belt part) requires complicated control, and there is a problem that the manufacturing equipment is complicated.
