Dispensing system and a dispenser

A dispenser comprising a housing for receiving a roll, the housing having a mount comprising a roll holder configured to support a keyed end of the roll and a roll support configured to support an opposing end of a roll;

• wherein the roll holder comprises a frame, a clutch plate, a spindle, and a biasing unit, the clutch plate being disposed adjacent the spindle, and the spindle being configured to receive the keyed end of the roll and being rotatably coupled to the frame to permit rotation of the roll with respect to the frame and the clutch plate about a dispensing axis;
• wherein the spindle comprises a clutch surface which directly opposes the clutch plate along the dispensing axis, and which is configured to cooperate with the clutch plate to resist relative rotation of the spindle and the clutch plate by friction;
• wherein the spindle is translatable along the dispensing axis with respect to the frame, and wherein the biasing unit is configured to bias the spindle in a direction along the dispensing axis away from the frame, such that mounting a roll onto the mount pushes the spindle towards the frame to increase a normal force between the clutch plate and the clutch surface of the spindle, thereby increasing the friction force;
• and
• wherein the frame comprises teeth which are configured to cooperate with teeth on the spindle facing the frame if a roll is mounted incorrectly to push the spindle towards the frame by more than a threshold distance, such that the teeth of the frame engage with the teeth on the spindle to lock rotation of the spindle relative to the frame.

• wherein the biasing unit is disposed between the frame and the clutch plate to further bias the clutch plate away from the frame;
• and
• wherein the clutch plate comprises a central column and the frame comprises a central hole configured to receive the central column, wherein the central column is configured to protrude from the central hole if the spindle is pushed towards the frame by more than a threshold distance, to limit pivoting movement of the mount back into the housing.
