advances a predetermined length of the paper from the
supply roll. The other roll 18 is usually a smaller roll
and may be conveniently termed a pressure roller.
The dispensing roll of the present invention preferably
comprises a core of wood or other suitable material hav
ing its gripping surfaces covered with rubber, as at 20.
Between the rubber covered portions there may be axially
spaced peripheral grooves 21 for a purpose which is not
important in the present invention.
