ABSTRACT METHOD OF AND APPARATUS FOR APPLYING ELASTIC BAND ONTO A MOVING WEB The method and apparatus are adapted for inter- mittently applying pieces (5) of elastic band severed into predetermined lengths onto a moving continuous web (8) at predetermined positions. The apparatus comprises elastic band transfer means (11) including a plurality of independently rotatable rotor elements (26) coaxially supported and carrying on respective arc-shaped outer surfaces suction members (12). The rotor elements (26) are rotated along common circumferential path and the respective rotor elements (26) are coupled to a drive eccentric relative to a rotational centre of the rotor elements and rotates at a constant speed by a slider crank mechanism; suction distributor means (13) for the suction members (10), operates synchronously with rotation of the drive wheel (20). Continuous elastic band is fed tangentially to the circumferential path of the suction members (10) means intermittently cooperates with one of the suction members (10) periodically advanced by the elastic band transfer means (11) to sever the continuous elastic band. Web feeding means (10) is opposed to an end position of transport of the severed piece of elastic band so that the piece of elastic band may be effectively transferred onto the web (8).
