Method of manufacturing RFID devices
First Claim
1. A method of making RFID devices, the method comprising:
- feeding portions of a free end of an interposer web into a cutter, wherein the feeding includes feeding an interposer of the interposer web and selectively feeding additional material at the free end of the interposer web;
cutting, in an iterative process, the interposer and the additional material, if any, from the free end of the interposer web onto a rotary transport mechanism;
transporting the interposer on the rotary transport mechanism;
transferring the interposer from the rotary transport mechanism to a moving antenna web; and
attaching the interposer to the antenna web, such that the interposer is operatively coupled to an antenna of the antenna web.

Abstract
A method of making RFID devices includes feeding in an interposer web or sheet at a variable (non-constant) speed, cutting single interposers from the interposer web or sheet, and using a rotary transport device to transport the singulated (cut) interposers to an antenna web. The interposers are transferred from the rotary transport device and are attached to the antenna web, being operatively coupled to antennas on the antenna web. The interposers each include an RFID transponder chip and conductive leads. A feeder is used to advance the interposer web or sheet into a cutting zone between the rotary cutter and the rotary transport device. The rotary cutting device may be capable of singulating multiple interposers at one time, and the system may be capable of thus being able to remove interposers that are not to be joined to the antenna web.

11. A fabrication system for making an RFID inlay intermediate web for use as label stock, comprising;
-
an interposer stock having a first pitch, the interposer stock having an integrated circuit provided on a polymeric material; a transporter for moving the interposer stock; a cutter for separating the interposer stock into individual interposers; a tester for testing each of the individual interposers; a rotary transporter for accepting the individual interposers and moving the individual transporter an antenna web; an antenna web handler for moving the antenna web in proximity to the rotary transporter to receive the individual interposer, the antenna web along with the interposer form an RFID inlay intermediate web having a second pitch distinct from the first pitch; and
;adhesive applicator for applying an adhesive and release material to the RFID inlay intermediate web to form an RFID inlay label stock. - View Dependent Claims (12, 13, 14, 15, 16)
