Abstract
A dispenser for sequentially dispensing web material from a primary web roll and then a reserve web roll. The dispenser senses the presence of the primary web directly at the feed nip defined by two feed rollers and introduces the leading edge of the reserve web roll to the feed nip immediately after the trailing end of the primary web roll passes through the feed nip. The movement of one feed roller relative to the other feed roller actuates the transfer mechanism which introduces the reserve web to the feed nip.
