1. A method of forming an RFID article, the method comprising:

  • providing an RFID webstock of polymeric material, the webstock having a plurality of RFID chips attached to the polymeric material at a first pitch and each RFID chip having an associated set of conductive pads on the polymeric material, and wherein the RFID chips are connected to the associated set of conductive pads;

    moving the RFID webstock in a first direction between a first transport member, that is configured to divide the RFID webstock, and a second transport member;

    dividing the RFID webstock into a plurality of sections without stopping movement of the RFID webstock, each section including one or more of the RFID chips and the associated set of conductive pads, wherein the first transport member includes a cutting section for dividing the RFID webstock into the plurality of sections against the second transport member that is moveable tangentially to the first transport member;

    securing at least some of the separated sections to the second transport member at a second pitch;

    transferring the sections on the second transport member to an antenna web, wherein the antenna web includes a plurality of antennas disposed thereon at the second pitch, and wherein the antenna web is moveable in a second direction opposite the first direction to receive the sections without stopping movement;

    attaching the sections to the antenna web without stopping movement of the web during or between successive attaching steps such that the associated set of conductive pads are operatively coupled to successive antennas, wherein the second transport member and a third transport member move the antenna web in the second direction, and wherein the sections are attached to the antenna web between the second transport member and the third transport member;

    transporting the webstock in the first direction with an in feed transport member to the first transport member and the second transport member; and

    transporting a web, formed by leftover material from the divided RFID webstock, in the first direction with an outfeed transport member from the first transport member and the second transport member.
