Abstract
An apparatus for cutting a roll of material includes an elongated blade having a distal end, a cutting guide attached to the elongated blade and positioned to direct the distal end of the elongated blade towards the roll of material, and a support position to hold the roll of material approximate to the elongated blade. A method for cutting a roll of material having an axis and a circumference is taught. The method comprises radially cutting the roll of material from the circumference to the axis by advancing the distal end of an elongated blade, then rotating the elongated blade relative the axis to cut the roll of material. Alternately, the method teaches rotating the roll of material relative to the axis to cut the roll of material.

An apparatus for cutting a roll of sheet material, comprising:
- a chain saw having an elongated blade, said elongated blade comprising sides that are generally parallel to one another, an end attached to a driving mechanism, and a free distal end that is shorter than and generally perpendicular to the sides and located opposite the attached end, wherein said blade is substantially planar and said blade is positioned substantially parallel to a circumference of said roll and substantially transverse to a central longitudinal axis of side roll;
- a cutting guide attached to the elongated blade and positioned to direct the distal end of the elongated blade into the roll of sheet material such that a chain crossing the distal end of the elongated blade plunge cuts the roll of sheet material along a linear insertion path that is substantially co-linear with a longitudinal axis of said elongated blade;
- at least one positioning guide configured to adjust the position of the cutting guide and the elongated blade relative to the roll of material;
- and
- a support positioned to hold a first end of the roll of material proximate to the elongated blade at only one end.
An apparatus for cutting a roll of sheet material, comprising:
- a cutting guide;
- a chain saw having an elongated blade, said elongated blade comprising elongated parallel sides, an end attached to a driving mechanism, and a free distal end opposite the attached end and being shorter and generally perpendicular to the elongated sides, wherein said blade is substantially planar and said blade is positioned substantially parallel to a circumference of said roll and substantially transverse to a central longitudinal axis of side roll;
- wherein the chain saw is attached to the cutting guide and positioned such that a chain crossing the distal end is plunge cut into the roll of sheet material along a linear insertion path that in substantially co-linear with a longitudinal axis of said elongated blade;
- at least one positioning guide configured to adjust the position of the cutting guide and the chain saw with respect to a central axis of the roll of sheet material;
- and
- a holding device positioned to support the roll of sheet material proximate to the chain saw at only one end.

- a cutting guide attached to the chain saw and positioned to direct the distal end of the chain saw to initially engage the roll of sheet material such that a chain crossing the distal end plunge cut the roll of sheet material along a linear insertion path that is substantially co-linear with a longitudinal axis of said blade;
- a holding device positioned to support the roll of sheet material proximate to the chain saw at only one end;
- and
- a stanchion attached to the cutting guide and including at least one position guide located on the stanchion to adjust the position of the cutting guide and the chain saw with respect to a central axis of the roll of sheet material.
