Abstract
Paired, coacting, albeit non-contacting rollers have interfitting collars or rings, and tapered rims, which are rotatably driven in opposite directions. Paper fed therebetween is torn asunder, and freely discharged therefrom. The rings cooperate together to force the paper to be torn lengthwise thereof, and the rims crease the resulting strips to insure that they do not remain lodged between the rings. An embodiment has helical rings or collars which cause the paper to be dismembered into diagonally-shaped, fine fragments.
