Embossing dispenser roll transfer assembly

摘要

Disclosed is transfer apparatus for use in an embossing dispenser capable of sequentially dispensing primary and secondary rolls of a sheet material. The transfer apparatus includes pivotally mounted transfer linkage which supports a primary roll contacting surface. Bar means attached to the transfer linkage has a comb projecting therefrom with a wing member extending from each end of the bar member. The transfer linkage is biased for rotational movement to maintain the primary roll contacting surface in contact with the primary roll as the primary roll is depleted. This biasing simultaneously rotates the bar means toward the embossing rollers. As the primary roll nears exhaustion, the wing members engage one of the embossing rollers to thereby position the comb means such that it partially invades the grooves of the embossing roller thereby moving the tail of the secondary roll into contact with one of the knuckled embossing rollers in close proximity to the nip such that the tail of the secondary roll is engaged by the knuckles of the embossing rollers and drawn through the nip. The wing members ensure that the comb means so positions the tail of the secondary roll without the comb interfering with either of the embossing rollers.
