ABSTRACT:
A dispenser for dispensing up to approximately one and one-half rolls of flexible sheet material. The dispenser includes a dispensing mechanism and a roll transfer and supporting mechanism. The roll transfer and supporting mechanism includes a pair of guide tracks, a pivotally spring biased sensor plate, a pair of opposing reserve roll supports, a pair of transfer links each connecting the sensor plate to a respective reserve roll support, a support roller, and a support surface located below the support roller. The guide tracks guide the core ends of the rolls through the dispenser. The reserve roll supports are pivotally mounted adjacent the upper end of the guide tracks, and hold a roll in a reserve position when a dispensing roll is smaller than a first predetermined diameter and greater than a second predetermined diameter. The pivotally mounted sensor plate senses the diameter of the dispensing roll and is coupled to the reserve roll supports, via the transfer links, to control the reserve roll supports in accordance with the sensed diameter.
