PROBLEM TO BE SOLVED: To provide a method for producing a diaper for a pet with little material loss, and high production efficiency.SOLUTION: The method for producing the diaper for the pet includes a step of transporting each of the sheet-forming straps 11 and 14 in the longitudinal direction thereof, a step of dividing each of the sheet-forming straps 11 and 14 in the width direction thereof, thereby connecting mutual straps 4 for the girth in the longitudinal direction, and forming two rows of diaper continuous bodies having a shape arranging a strap 5 for the belly part in the longitudinal direction, respectively, a step of forming a slit 6 for a tail in a part corresponding to the strap 5 for the belly part of each of the sheet-forming straps 11 and 14, and a step of cutting each of the diaper continuous bodies into each diaper for the pet. In the step of forming the diaper continuous bodies, each of the sheet-forming straps 11 and 14 is divided along a dividing line S1 meandering in the width direction so that the strap 5 for the belly part of each of the diaper continuous bodies is alternately arranged in the longitudinal direction.COPYRIGHT: (C)2010,JPO&INPIT【課題】材料のロスが少なく、かつ、生産効率の高いペット用おむつの製造方法を提供すること。【解決手段】各シート形成帯11,14をその長手方向に搬送する工程と、各シート形成帯11、14をその幅方向に分断することにより、胴回り用帯4同士が長手方向に連結され、かつ、腹部用帯5が長手方向に並ぶ形状をそれぞれ有する2列のおむつ連続体を形成する工程と、各シート形成帯11、14の腹部用帯5に相当する部分に尻尾用スリット6を形成する工程と、各おむつ連続体をペット用おむつに切り分ける工程とを含み、前記おむつ連続体を形成する工程では、各おむつ連続体の腹部用帯5が長手方向に交互に並ぶように、前記幅方向に蛇行する分断線S1に沿って各シート形成帯11、14を分断する。【選択図】図1
