  • Method of separating and placing discrete elements
    Patent number: 6599384
    Abstract: A method and apparatus are provided for separating a discrete element from a first substrate web, moving at a first speed, and placing the discrete element on a second substrate web, moving at a second speed. The apparatus includes a first station, wherein perforations are made in the first substrate web, and a second station, wherein the discrete element is separated from the first substrate web at a line of perforations and the discrete element is transferred to a positioned on the second substrate web. The first station includes a perforation cutter assembly and conveyer assembly. The perforation cutter assembly includes first and second rollers with a cutting blade, with a discontinuous edge, and an anvil surface, respectively, to make perforations in the first substrate web. The second station includes a separation and transfer mechanism having separation and transfer segments for separating and transferring the discrete element from the first substrate web to the second substrate web.
