Here is disclosed a process for attaching indicator elements onto a disposable garment comprising the steps of feeding a plurality of liquid-absorbent cores C and a plurality of indication sheets 13 each having indicator elements 14 onto inner and outer surfaces of a first outer layer web 30, respectively placing a rear half 13b of the front sheet A13 of each pair of the indication sheets adjacent to each other in a machine direction 13 upon a front end zone C1 of the core C and placing a front half 13a of the rear sheet B13 of the indication sheets adjacent to each other in the machine direction upon a rear end zone C3 of the core C joining the indication sheet 13 to the outer layer web 30, joining the core C to the inner and outer layer webs and joining the webs together cutting the indication sheet together with the inner and outer layer webs between each pair of the cores C in a cross direction so as to obtain a plurality of the inner panels arranged in the machine direction and after turning around the inner panels in the cross direction, arranging the inner panels on the inner surface of the outer web at regular intervals and joining an outer surface of the outer layer web to an inner surface of the outer web.
