Abstract: Disclosed herein is a cutting frame including a plurality of cutters for cutting one or more kinds of rectangular unit pieces having a relatively small size from a rectangular base material at a predetermined inclination, the cutters being mounted or formed in the cutting frame such that the cutters correspond to the rectangular unit pieces, wherein the cutters are mounted or formed in the cutting frame based on the array structure of the rectangular unit pieces such that a large majority of the remaining rectangular unit pieces, excluding the uppermost row rectangular unit pieces and the lowermost row rectangular unit pieces, are arranged while being adjacent to different rectangular unit pieces at four sides of each rectangular unit piece, and at least some combinations of adjacent four rectangular unit pieces form an island-type residue in the center thereof.

Abstract: Disclosed herein is a method of manufacturing one or more kinds of rectangular unit pieces from a long base material sheet at a predetermined angle through a continuous cutting process using a cutting frame, the method including (a) manufacturing a base material sheet of a laminate structure having two or more stacked sheets and winding the base material sheet on a roll, (b) continuously feeding the base material sheet, wound on the roll, (c) cutting the fed base material sheet using a cutting frame having cutters mounted or formed therein in a structure in which the cutters correspond to rectangular unit pieces to be manufactured, the cutters being arranged such that the shapes of opposite side ends of the cutters coincide with each other when the cutters are successively arranged, the cutting being carried out while the base material sheet is partially overlapped such that a length (‘pitch’) for a one-time cutting process is equal to a spacing distance between the opposite side ends of the cutters in the lo

Abstract: Disclosed herein is a cutter frame including a plurality of cutters for cutting one or more kinds of rectangular unit pieces having a relatively small size from a rectangular base material at a predetermined inclination, the cutters being mounted or formed in the cutter frame such that the cutters correspond to the rectangular unit pieces, two of the rectangular unit pieces being arranged mainly in the inclination direction such that the rectangular unit pieces are in contact with each other at one side of each rectangular unit piece, wherein, on the assumption that imaginary vertex coordinates of a leftmost end are (Ax, Ay), and imaginary vertex coordinates of a rightmost end are (Bx, By), when the rectangular unit pieces coincide with each other at a left or right side of each rectangular unit piece, vertex coordinates (B?x, B?y) of the rightmost end are greater than the imaginary vertex coordinates (Bx, By) of the rightmost end based on the imaginary vertex coordinates (Ax, Ay) of the leftmost end in an ar
