SHEET MATERIAL DISPENSER

摘要

Apparatus for dispensing sheet material from a sheet material dispenser (10) are described. Dispenser embodiments include drive (19) and tension rollers (17) supported within a housing (11) forming a nip (79) therebetween. Pulling of sheet material (29) through the nip (79) and against the drive roller (19) rotates the drive roller. Dispenser embodiments may include a cutting mechanism (61) powered by drive roller (19) rotation with an improved carrier-supported (103) blade (101) permitting highly-efficient dispenser operation. Dispenser embodiments may include a sheet material tail length adjuster (23) which permits the attendant to shorten or lengthen the tail (30) length extending away from the dispenser. Dispenser embodiments may further include a sheet material conservation feature (21) which imposes a delay between dispense cycles encouraging use of a single sheet of material and discouraging sheet material waste.
