TITLE DISPENSING APPARATUS ABSTRACT OF THE DISCLOSURE A dispensing apparatus for dispensing two strip materials, each carried on a separate spool, includes a hub having a slot therein which exposes a portion of one but not the other of the spools. A friction producing member is extensible through the slot and into friction generating engagement with the selected one of the spools to exert a drag force on one of the spools to the exclusion of the other. The friction producing member is received in a groove formed in a spindle so that torque imposed on the member by rotation of the spool is transmitted to the spindle.
