1. A method of forming an RFID article, the method comprising the steps of:
- providing an RFID webstock of polymeric material having a plurality of recesses, each of the recesses containing an RFID chip;
providing a second web having antennas as spaced thereon;
dividing the RFID webstock into a plurality of sections, each of the sections including one or more of the RFID chips and a portion of the polymeric material;
indexing the pitch of the RFID sections from high density on said RFID webstock, to a relatively low density on an RFID inlay stock; and
attaching the sections to the antennas in an automatic continuous process, so that each of the RFID chips is adjacent to one of the antennas to form the RFID inlay stock.

Abstract
An RFID webstock containing a relatively high pitch-density array of semiconductive chips is provided and joined to a web bearing relatively widely spaced antennas in a continuous process. The RFID webstock is separated or cut into individual chip sections, with the spacing of the chips being increased as the RFID webstock is die cut. The individual chips on the sections are then joined to corresponding antennas to form an RFID inlay stock. This process is conducive to high speed roll-to-roll production of RFID tag and label roll stock.

20. A method of forming an RFID article, the method comprising the steps of:
-
providing an RFID webstock of polymeric material having a plurality of recesses, each of the recesses containing an RFID chip;
providing a second web having antennas as spaced thereon;
dividing the RFID webstock into a plurality of sections, each of the sections including one or more of the RFID chips and a portion of the plymeric material;
