A method for rejecting defective absorbent articles from a web converting manufacturing process, the method comprising the steps of: converting a substrate and component parts into a continuous length of absorbent articles; inspecting the substrate or at least one component part with a sensor; communicating inspection parameters from the sensor to a controller; cutting the continuous length of absorbent articles into discrete absorbent articles; identifying defective discrete absorbent articles based on the inspection parameters; advancing the discrete absorbent articles in a machine direction on a first carrier; applying a vacuum pressure to the first carrier to hold the discrete absorbent articles on the first carrier; transferring a plurality of the discrete absorbent articles from the first carrier onto carrier members at a pick-up zone proximate the first carrier; moving carrier members from the first position proximate the first carrier to a second position proximate a second carrier; and transferring the plurality of the discrete absorbent articles from the carrier members to the second carrier at a drop off zone; and rejecting the defective discrete absorbent articles before the defective absorbent articles are transferred to the carrier members by advancing the defective discrete absorbent articles on the first carrier past the pick-up zone.
