Patent ID: 7971514

Claim:
An apparatus for producing rolls of disposable pieces of hygienic paper, the apparatus comprising: (a) a spiral blade cylinder having a spiral blade cylinder rotation axis; (b) a spiral blade having a spiral blade radius, wherein said spiral blade is disposed upon said spiral blade cylinder; (c) a segmented blade cylinder having a segmented blade cylinder rotation axis; (d) a first segmented blade having a segmented blade radius, at least two bladed segments, and at least two blade lateral space, said first segmented blade is disposed upon said segmented blade cylinder, wherein each one of said bladed segments has a width dimension larger than each one of said blade lateral spaces' width dimension; and (e) a second segmented blade having a segmented blade radius, at least two bladed segments, and at least two blade lateral spaces, said second segmented blade is disposed at said segmented blade cylinder, wherein each one of said bladed segments has a width dimension larger than each one of said blade lateral spaces' width dimension, wherein said segmented blade cylinder rotation axis, said first segmented blade, and said second segmented blade are laying upon a common plane, wherein a bladed segment of said first segmented blade is facing a lateral space of said second segmented blade, and wherein a distance between said spiral blade cylinder rotation axis and said segmented blade cylinder rotation axis is substantially the sum of the spiral blade radius and the segmented blade radius.
