Abstract
An apparatus and method for applying discrete segments to a continuous web includes feeding a first continuous web to a roller, the first continuous web comprising one or more layers, feeding a second continuous web to a vacuum anvil, cutting the first continuous web into a plurality of discrete segments via interaction of the roller with at least one cutting element selectively positionable adjacent the roller, transferring each of the plurality of discrete segments from the roller onto the second continuous web at a first location and via a vacuum pressure from the vacuum anvil, and bonding each of the plurality of discrete segments to the second continuous web at a second location downstream from the first location in a machine direction, each of the plurality of discrete segments bonded to the second continuous web via interaction of the vacuum anvil with a bonding device positioned at the second location.
