Apparatus for dispensing sheet material from a sheet material dispenser are described. Dispenser embodiments include drive and tension rollers supported within a housing forming a nip therebetween. Pulling of sheet material through the nip and against the drive roller rotates the drive roller. Dispenser embodiments may include a cutting mechanism powered by drive roller rotation with an improved carrier-supported blade permitting highly-efficient dispenser operation. Dispenser embodiments may include a sheet material tail length adjuster which permits the attendant to shorten or lengthen the tail length extending away from the dispenser. Dispenser embodiments may further include a sheet material conservation feature which imposes a delay between dispense cycles encouraging use of a single sheet of material and discouraging sheet material waste.
