ABSTRACT:
A web unwinding and splicing apparatus includes two carts each supporting a plurality of web rolls, along with a first and second drive mechanism for selectively moving either cart. The carts are alternately advanced by a controller as web rolls carried by the carts are alternately depleted. The apparatus provides continuous unwinding for relatively long periods of time without operator attention.
