ABSTRACT:
A multiple roll towel dispenser. The dispenser cabinet has a pair of feed rollers forming a feed roll nip, means for driving one of the feed rollers to dispense web from the cabinet, means in the cabinet for supporting a first roll of web material with its web extended between the feed roll nip, and means for supporting a second roll of web material with its web extended adjacent to the feed roll nip. The dispenser also includes means, contacting the edge of the first roll, having a first position for sensing the diameter of the first roll; means, connected to the sensing means, for biasing the sensing means against the edge of the first roll; biased transfer means for introducing the extended web of the second roll into the feed roll nip; and stop means, connected to the sensing means, the stop means being located to resist motion of the transfer means at a ready position when the edge of the first roll resists movement of the sensing means. When the edge of the first roll no longer resists movement of the sensing means, the sensing means and connected stop means moves to a second position which allows the biased transfer means to move to a transfer position where the extended web of the second roll is introduced into the feed roll nip.
