The present invention includes: a transport mechanism that transports a lower belt-shaped member and an upper belt-shaped member in a transport direction an adhesive-area forming mechanism that applies an adhesive on both sides of a cutting position in the transport direction of at least one of the lower belt-shaped member and upper belt-shaped member to form adhesive areas thereon an elastic member arrangement mechanism that arranges a plurality of elastic members stretched in the transport direction so that portions thereof overlap the adhesive areas a superposing mechanism that superposes the lower belt-shaped member and upper belt-shaped member so as to sandwich the elastic members and an elastic member cutting mechanism having a first cutter that cuts the plurality of elastic members between two cutting positions adjacent in the transport direction and between two adhesive areas adjacent in the transport direction, a second cutter that cuts the elastic members at the cutting position, and an operation member that supports the first cutter and second cutter and operates the same in a predetermined direction.La présente invention comprend : un mécanisme de transport, qui transporte un élément en forme de courroie inférieure et un élément en forme de courroie supérieure dans une direction de transport un mécanisme de formation de zone adhésive, qui applique un adhésif sur les deux côtés dune position de coupe dans la direction de transport dau moins un de lélément en forme de courroie inférieure et lélément en forme de courroie supérieure, pour former des zones adhésives sur ce dernier un mécanisme dagencement délément élastique, qui agence une pluralité déléments élastiques étirés dans la direction de transport de telle sorte que des parties de ces derniers chevauchent les zones adhésives un mécanisme de superposition, qui superpose lélément en forme de courroie inférieure et lélément en forme de courroie supérieure de façon à prendre en sandwich les éléments éla
