Abstract
A device for forming elastication strips applicable in stretched condition, for example along the waistline of sanitary articles such as diapers and the like, includes at least one pair of combined drawing members suitable for operating in gripping relation on the ends of the strips to receive the strips themselves arranged bridge-like therebetween in non-stretched condition at an inlet end of the device. The drawing members are moveable according to trajectories diverging from each other to draw the strips arranged bridge-like therebetween towards an outlet end of the device. The drawing members are moved by motor means with selectively variable velocity when transferring the strips between the inlet end and the outlet end to selectively vary the application pitch of the strips in stretched condition on the sanitary articles.
