Roll product dispenser with improved cutting mechanism

An apparatus for dispensing and cutting measured amounts from a roll of web material, said apparatus comprising:

• a housing;
• a roll carrier disposed within said housing to rotationally carry a roll of web material to be dispensed;
• a rotatable drum disposed within said housing proximate to said roll carrier, said roll carrier biased towards said rotatable drum so that the roll of web material carried by said roll carrier is frictionally engaged against said drum thereby causing said drum to rotate upon a free end of the web material being pulled from said housing;
• a rotatable cutting mechanism mounted within said housing external of and adjacent to said rotatable drum, said cutting mechanism including at least one cutting blade that moves across a conveying path of the web material as said cutting mechanism rotates to automatically cut the web material;
• and
• wherein said cutting mechanism is engaged and moved by said rotatable drum along a portion of a complete rotational arc of said rotatable drum causing said cutting mechanism to rotate and cut the web material, and said cutting mechanism is stationary and disengaged from said rotatable drum along a remaining portion of the complete rotational arc of said rotatable drum wherein said cutting mechanism rotates less than a full revolution per complete rotational arc of said rotatable drum.
