Abstract:
A method for forming a continuous web of material from a block of material having a central axis and a first density, the method comprising the steps of:(a) providing the block of material;(b) submersing a substantial portion of the block in a liquid disposed in a bath and having a second density, wherein at least a portion of the block is disposed above the liquid in the bath;(c) providing a cutting device having a cutting blade which is positioned a predetermined distance from the central axis of the block of material and disposed generally parallel to the central axis;(d) rotating the block of material about the central axis;(e) linearly advancing the central axis of the block of material a predetermined distance toward the cutting device while rotating the block of material such that the continuous web is produced as the cutting device cuts in a substantially spiral path through the block of material; and(f) controlling the predetermined distance between the cutting device and the central axis such that the continuous web cut from the block of material is of substantially uniform thickness.
