An apparatus and process for attaching elastic strips in elastic leg disposable diapers having gathered and extendible side portions in the crotch area during manufacture of such diapers in an assembly machine including mechanisms for alternately stretching and relaxing predetermined lengths of the elastic strips for adhesive attachment of the stretched lengths to the crotch area and the more relaxed lengths to the outer waist areas continuously along the edges of the diaper. These mechanisms include devices for feeding elastic strips at a predetermined constant rate for adhesive attachment in the diaper, nipping mechanisms engaging the elastic strips and defining a predetermined distance of travel of the elastic strips therebetween, movable devices for engaging the elastic strips and for alternately moving to other positions to vary the distance of travel of the elastic strips for alternately stretching and relaxing the elastic strips and compensating mechanisms for maintaining the stretching and the relaxing, respectively, during feeding of the stretched and relaxed lengths.
