<p>A web unwinding and splicing apparatus (10) includes two carts (14a, 14b) each supporting a plurality of web rolls (28a-e, 29a-e), along with a first and second drive mechanism (60, 62) for selectively moving either cart (14a, 14b). The carts (14a, 14b) are alternately advanced by a controller (90) as web rolls (28a-e, 29a-e) carried by the carts (14a, 14b) are alternately depleted. The apparatus (10) provides continuous unwinding for relatively long periods of time without operator attention.</p> |
