ABSTRACT:
This invention provides an improved web transfer mechanism in a paper roll towel dispenser of the type having a primary roll and a reserve roll of paper toweling. The transfer mechanism comprises a cradle for supporting the primary roll that is counterbalanced by an element for tucking the leading end of the reserve roll into the nip between feed rollers. As the primary roll becomes depleted, the counterbalancing force of the roll decreases, causing the tucking element to gradually approach the leading end of the reserve roll until the element finally engages the end and introduces it into the nip. In a preferred embodiment, the device includes a damper mechanism to prevent premature introduction of the leading end caused by the tendency of the primary roll to rise above the cradle by a sudden pull on the toweling.
