Abstract: A method for manufacturing of cartons by a carton manufacturing system comprising a piece assembly unit and a piece attaching unit. The method may comprise steps: A) retrieving a set of measurements of an intended content to be enclosed in a final carton; B) calculating a width X1 and a length Y1 of a first carton piece, and a width X2 and a length Y2 of a second carton piece; C) providing the first carton piece with the width X1 and the length Y1, and a second carton piece with the width X2 and the length Y2; D) assembling the first and the second carton piece into a detachable carton piece assembly; and E) attaching the first and the second carton piece to form a carton assembly by placing a first edge of the first carton piece is against a second edge of the second carton piece.

Abstract: A method to accomplish manufacturing of cartons, that supports the objective to decrease relatively large volumes of unnecessary air shipped, and to standardise size aspects of raw material so that logistics of raw material use for cartons and carton manufacturing process can be optimized. The method comprise steps from the retrieval of measurements for intended content to be closed, to calculating required width and length of standardized sized carton pieces having width dimensions based on geometrical series 2, 4, 8, 16, 32, 64, and then cutting and re-join cardboard pieces edge to edge by an adhesive, to assemble a carton piece that matches a calculated required cardboard size for further forming and folding of a cardboard box, as described by the method, with minimal loss of carton material.
