Claim Text:
1. An aluminum foil and stretch film cutting machine comprising a main body having a cutter mechanism; an upper cover with sharp teeth along a front long edge and mounted to the main body from a back long edge; a roll shaft to which a roll is to be placed in the main body; a roll shaft bearing placed inside a right module in a main body wall and whereon the roll shaft is to be placed; a flexible roll shaft fixing nail enabling the fixation of the roll into a bearing part in a lower part of the roll shaft bearing; a plus-shaped hole on the other opposite edge of the roll shaft; a helical spring gear positioned to be placed into the plus-shaped hole in the edge part of the roll shaft; a plus-shaped protrusion positioned to place the roll shaft onto the helical spring gear; a helical spring inside a hole in a center behind the helical spring gear; a helical spring gear nail; an interior mechanism body whereon an interior mechanism is placed; a detent gear behind the helical spring gear of an interior mechanism body cover; a detent; a transmission gear positioned in a way that a plurality of teeth of the transmission gear are engaged in the teeth of the detent gear and that transmits the movement of the detent gear to a conical transmission gear; the conical transmission gear coupled to the transmission gear; a cutter gear perpendicularly positioned in front of the machine with a 90.degree. angle to the conical transmission gear and capable of rotating by the movement of the conical transmission gear; a cutter having zigzag teeth thereon and positioned in the part contacting with the cover in an upper front part of the main body, the cutter performing the foil or film cutting operation by moving forward and backward with the movement of the cutter gear; a cutter spring that is positioned immediately below the cutter in a way that the cutter spring will be in a middle part and that supports back and forth movement of the cutter; two cover pins positioned close to two corners where the upper cover is connected to the main body; a cover spring pin positioned immediately below the cover pin such that the cover spring pin will contact with cover pin; and the cover spring below cover spring pin, the cover spring being fixed onto a bottom of the main body.
