A process for realizing blanks for the manufacture of boxes to measure, characterized in that it includes the following stages: —collecting at least a sheet of packing material from at least a store; —transferring it to a cutting station in which the sheet itself is cut so that a plurality of pieces is obtained therefrom, which plurality of pieces exhibits a common dimension and other dimensions which are different from one another according to predetermined ratios; —collecting the pieces, according to the dimensions of the box to be formed, in order to cut them into the predetermined dimensions, after joining, when necessary, one or more of said dimensionally homogeneous pieces so as to form a piece that is longer than the one available and suitable for constituting the “bottom” piece, which includes the bottom and at least two first opposite lateral walls of the box to be formed; cutting to measure said pieces and subjecting them singly to a first and a second marking in order to obtain weakened or folding lines in predetermined positions; —and after removal, if necessary, of corner portions of some pieces, carrying out the composition thereof in order to form a single body constituting the blank, flat, complete and ready to be folded and glued to form the box.

1. A process for realising boxes to measure, characterised in that it comprises the following steps: collecting a sheet (10) of packing material from a store (1) of unprocessed material constituted by sheets (10) of packing material having predetermined dimensions and arranged to form a stack;transferring the sheet (10) collected from the store (1) to a cutting station (2) and cutting the sheet (1) into a plurality of pieces (11, 12, 13, 14), which plurality of pieces (11, 12, 13, 14) exhibit (a) a common longitudinal dimension and (b) lateral dimensions which are different from one another according to predetermined ratios wherein the longitudinal dimension is length, and wherein the lateral dimensions are widths;transferring the pieces (11, 12, 13, 14) on command to at least a plurality of stores (31, 32, 33, 34), each of which is predisposed to house dimensionally homogeneous pieces in stacks;collecting, on command, from one of the stores (31, 32, 33, 34) which is preselected according to one of the dimensions of a box to be formed, single pieces for forming a bottom of a box and two first opposite lateral walls (24) thereof;collecting, on command, from one of the stores (31, 32, 33, 34) which is preselected according to another of the dimensions of a box to be formed, two second opposite lateral walls (25) thereof;joining, if necessary, two or more dimensionally-homogeneous pieces one after another to form a longer piece with respect to the dimensionally-homogeneous pieces housed in a corresponding store (31, 32, 33, 34), the longer piece being adapted to constitute a bottom piece (20) which comprises the bottom and at least two first opposite lateral walls (24) of the box being formed;cutting to measure said bottom piece (20);cutting to measure other lateral pieces (21), dimensionally homogeneous to one another and destined to form the two second opposite lateral walls (25);transferring the bottom and lateral pieces (20, 21) on a work plane (4);a first marking or scoring, singly operated, either on the lateral pieces (21) or on the single bottom piece (20) for realising, at predetermined positions of each piece, first weakened or scored lines parallel to each other;a second marking or scoring, for realising either on the bottom piece (20) and/or on the lateral pieces (21) in predetermined positions, second weakened or scored lines which are perpendicular to the first weakened or scored lines;optionally removing corner portions of some of the bottom and/or lateral pieces (20, 21) previously cut to measure; andjoining the bottom and lateral pieces (20, 21), previously cut to measure, to form a single body constituting the blank (40), flat, complete and ready to be folded and glued to form the box. 2. The process of claim 1, characterised in that the single pieces (20) for forming the bottom of the box and at least two first opposite lateral sides (24) thereof, also comprise one or more walls (26) to form a cover of the box and adapted to be fixed on flaps (18), appropriately folded on the weakened or scored lines of the lateral walls (21). 3. The process of claim 2, characterised in that the sheets (10) of packing material having predetermined dimensions and arranged to form a stack are identical to one another at least with reference to length and width. 4. The process of claim 2, comprising the joining of the two or more dimensionally-homogeneous pieces one after another and thereby forming a continuous strip, the joining being done at ends of smaller dimensions of the two or more pieces. 5. The process of claim 1, characterised in that the sheets (10) of packing material having predetermined dimensions and arranged to form a stack are identical to one another at least with reference to length and width. 6. The process of claim 1, comprising the joining of the two or more dimensionally-homogeneous pieces one after another and thereby forming a continuous strip, the joining being done at ends of smaller dimensions of the two or more pieces. 7. The process of claim 6, characterised in that the joining of the pieces at the ends thereof is done by partially superposing and reciprocally fixing the ends. 8. The process of claim 7, characterised in that the joining of the pieces at the ends thereof is done by partial superposing and relative gluing of the superposed parts.
