1. A method for producing a shoe sole, the method comprising:
preparing plates to be cut out, wherein the plates are a flat plate for a pillar piece with a first thickness and a flat plate for a protective cover with a second thickness thinner than the first thickness;
forming a first laminate, wherein the plate for a protective cover is disposed on an upper surface of the plate for a pillar piece, and the plate for a pillar piece and the plate for a protective cover are cut out, such that the plate for a pillar piece is divided into a plurality of first pieces of cut material and a first remaining portion of cut material and the plate for a protective cover is divided into a plurality of second pieces of cut material and a second remaining portion of cut material, and the plurality of second pieces of cut material has a same shape and position as a shape and position of the plurality of first pieces of cut material;
forming a second laminate, wherein the first laminate is seated on a laminate seating plate which has a plurality of protrusions for a piece of cut material protruding on an upper surface thereof with the same shape and position as the shape and position of the plurality of first pieces of cut material such that the first pieces of cut material of the first laminate are located above the protrusions for a piece of cut material, the first pieces of cut material and the second pieces of cut material are moved upward by the protrusions for a piece of cut material in a state in which the first remaining portion of cut material and the second remaining portion of cut material are seated on the laminate seating plate to move upward upper surfaces of the first pieces of cut material to the same level as an upper surface of the second remaining portion of cut material, and the second pieces of cut material moved upward are removed to form the second laminate which is the first laminate without the plurality of second pieces of cut material;
forming a fabric-bonded laminate, wherein a pre-cut fabric is bonded to an upper portion of the second laminate to form the fabric-bonded laminate in which the first pieces of cut material and the second remaining portion of cut material of the second laminate are bonded to a lower surface of the pre-cut fabric;
forming a cut material for an insole, wherein the fabric-bonded laminate is cut in a vertical direction thereof to be divided into the cut material for an insole and an outer remaining portion of cut material, the cut material for an insole having a plan of a form of a sole and with the first pieces of cut material being located inside the cut material for an insole and the outer remaining portion of cut material being located outside the cut material for an insole; and
separating a shoe sole, wherein the cut material for an insole is separated from the outer remaining portion of cut material to obtain the shoe sole comprising the cut material for an insole by separating.
