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 αand α, 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 βand βsmaller than the first amplitudes αand α, and being in synchronism with the first waveform α.
