ABSTRACT:
A dispenser for flexible sheet material rolls in which a first roll is supported in a dispensing position, a second roll is supported in a reserve position and a roll transfer apparatus is operative to transfer the second roll to the dispensing position upon depletion of sheet material from the first roll with the supporting arrangement for the roll in the dispensing position being rotatable with such roll and thereby subject to significantly reduced friction effects. The described dispenser organization also includes a novel arrangement for retaining the cores and spindles of spent rolls within the dispenser until the closure cover is opened for replenishing the dispenser with fresh rolls whereupon, by opening the cover, the spent residual roll elements are automatically deposited into the opened cover that forms a receptacle from whence the elements can be retrieved for disposal and following which the dispenser organization is automatically returned to its operative condition in a single step upon simply closing the closure cover. In order to retard the fall of a roll to the dispensing position, and thereby avoid injury or unpleasant surprise to a user and reduce noise upon roll transfer, a star wheel may be mounted to be contacted and rotated by a falling roll.
