摘要：A method and apparatus are provided for separating a discrete element from afirst substrate web, moving at a first speed, and placing the discrete element on a secondsubstrate web, moving at a second speed. The apparatus includes a first station, whereinperforations are made in the first substrate web, and a second station, wherein thediscrete element is separated from the first substrate web at a line of perforations andthe discrete element is transferred to a positioned on the second substrate web. Thefirst station includes a perforation cutter assembly and conveyer assembly. The

perforation cutter assembly includes first and second rollers with a cutting blade, with adiscontinuous edge, and an anvil surface, respectively, to make perforations in the firstsubstrate web. The second station includes a separation and transfer mechanism havingseparation and transfer segments for separating and transferring the discrete elementfrom the first substrate web to the second substrate web. The method includes the

steps of: making perforations across a width, at least partially through a thickness, and atpredetermined spaced apart intervals along a length of the first substrate web;separating the discrete element from the first substrate web along a first line of theperforations; and placing the discrete element on the second substrate web.
