An apparatus for dispensing sheets of web material of predetermined length from a supply of the web material comprising:
- a housing,
- means for storing the supply of web material in the housing, and
- separating means arranged in the housing for separating a sheet of the web material from the remainder thereof in response to a user of the apparatus pulling from the housing the free end of web material in the storing means,
- the separating means comprising a roller mounted for rotation in the housing, means for guiding the free end of the web over the roller and into frictional driving engagement therewith as it is pulled from the housing, and cutting means arranged on the surface of the roller to provide a cutting line at least part of which extends at an angle other than zero to the axis of the roller such that when a sheet of the web is withdrawn by the user a portion of the leading edge of the remainder of the web is simultaneously advanced outside the housing solely as a direct result of such withdrawal to be available for gripping by a subsequent user.
