Abstract
A method for producing a worn article, capable of providing a desirable wearability while reducing the cost of production. The method includes the steps of: placing leg elastic members F along a first waveform α on a web W being carried, the first waveform α being continuous in a longitudinal direction L of the web W and having a predetermined wavelength λ and predetermined first amplitudes α1 and α2, thereby producing a composite sheet Ws; and cutting off the composite sheet Ws being carried, along a cut-off line CL having a second waveform β being continuous in the longitudinal direction L of the composite sheet Ws, having a wavelength λ equal to the wavelength λ and second amplitudes β1 and β2 smaller than the first amplitudes α1 and α2, and being in synchronism with the first waveform α.
Claims4
A method for producing a worn article, including a first torso portion covering a part of a torso of a wearer, a second torso portion covering another portion of the torso of the wearer, and a core portion covering a crotch of the wearer, the method comprising the steps of:
- carrying a strip-shaped web being continuous in a carrying direction and having a first side edge portion and a second side edge portion;
- placing a leg elastic member along a first waveform on the web being carried, the first waveform being continuous in a longitudinal direction of the web and having a predetermined wavelength and a predetermined first amplitude, thereby producing a composite sheet;
- cutting off the composite sheet being carried, along a cut-off line having a second waveform being continuous in the longitudinal direction of the composite sheet, having a wavelength equal to the predetermined wavelength and a second amplitude smaller than the first amplitude, and being in synchronism with the first waveform, thereby dividing the composite sheet into a first separate sheet including the first side edge portion and having first depressed portions and first protruding portions alternating each other along the cut-off line and a second separate sheet including the second side edge portion and having second protruding portions and second depressed portions alternating each other along the cut-off line, and cutting off the elastic member;
- shifting a phase of the first separate sheet and a phase of the second separate sheet from each other in a flow direction so that the first protruding portion and the second protruding portion faces each other;
- and
- placing the core portion so as to bridge between the first protruding portion and the second protruding portion.
