A dispenser for sheet material such as paper towels. The paper towels are provided in a continuous roll. The roll is mounted within an enclosure above a drum. The drum contains a cutting assembly that moves between a retracted position and a cutting position. The cutting assembly cuts the sheet material when in the cutting position. The sheet material frictionally engages the drum such that pulling the sheet material out of the enclosure causes the drum to turn. The turning of the drum causes the cutting assembly to move between the retracted and cutting positions once every revolution of the drum. More specifically, a guide projection is formed on the cutting assembly, and a track assembly is formed on the enclosure. The guide projection engages the track assembly to cause the cutting assembly to move between the retracted and cutting positions.
