Surveillance tags (1) are manufactured by initially producing resonator elements (14) and bias elements (12) in batches in cells (21, 22). There is in-line testing of the resonator elements (14) as they are cut, and dynamic feedback to the cutter to adjust cutting parameters. Bias elements (12) are cut by drawing two webs (41, 42) from reels in side-by-side juxtaposition. Each web is drawn through fixed and dancing rollers for correct tensioning. The webs (41, 42) are fed by a feeder (70) comprising a pair of feed rollers (71(a), 71(b)) for each web, and a feed block (72) having a ramped loading section (74) located between the feed rollers. The feed block (72) has a groove (73) for each web, the groove having upwardly and inwardly extending side walls for web retention. <IMAGE>
