Abstract
The invention is directed to improved apparatus for dispensing flexible web material from plural rolls including improved transfer apparatus for reliably and simply dispensing material from a secondary roll once a primary roll has been depleted. The improved transfer apparatus comprises a one-piece transfer arm, first and second transfer rollers rotatably secured with respect to the transfer arm and a sensing member secured with respect to the transfer arm in position to contact the primary roll web surface. The sensing member permits movement of the transfer arm and transfer rollers to a transfer position once the primary roll diameter diminishes to a predetermined extent causing the secondary roll material to be dispensed.
