Method of manufacturing RFID devices
First Claim
1. A method of forming an RFID device, the method comprising:
- feeding a free end of an interposer web into a cutter, wherein the feeding includes moving the free end with a non-constant speed;
butt cutting an interposer 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,wherein the butt cutting includes using a rotary cutter to butt cut the interposer onto an anvil of the rotary transport mechanism;
wherein the rotary cutter includes multiple blades configured for contacting different locations on the free end of the interposer web in a single cutting operation; and
wherein the butt cutting includes selectively using the multiple blades to butt cut additional material along with the interposer, wherein the interposer and the additional material are butt cut substantially simultaneously in the single cutting operation.

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.
