  • the invention also relates to blanks and half blanks. of the type defined above.
  • the invention finds a particularly important application although non-exclusive in the field of manufacturing corrugated cardboard parallelepiped boxes or equivalent of large dimensions, for example of dimensions greater than 800 mm x 1 m.
  • the two suites of shutters are glued one to the other by an operator, the formed body presenting a semi-automatic or known type background under the name American treasury to be formed and folded manually.
  • the present invention aims to provide a method, a blank and a half blank responding better than those previously known to the requirements of practice, especially in that it allows the realization automatic large boxes can have an automatic background, so reliable, fast and perfectly repetitive, for a minimal cost.
  • the invention also proposes a blank or a set of half-blanks for an automatic cash register, made of a sheet of cardboard or corrugated cardboard, each half of blank or each half-blank comprising a series of at least two rectangular flaps, namely a first flap and a second flap, said flaps being interconnected by first fold lines parallel to each other, and comprising a set of lateral flaps connected to one side of said series by second fold lines perpendicular to the first fold lines, characterized in that the set of lateral flaps comprises a first rectangular or substantially rectangular flap comprising a double 45 ° bias fold line from one end of the second fold line joining with the first flap, defining a triangular end portion of first flap, and a second trapezoidal flap having a biased side, at 45 ° with respect to the second fold line joining with the second flap, said flaps being suitable for forming the bottom of said box.
  • the doubles fold lines are angled from the end of the second fold line located on the side of the second flap, the bias side of the second flap being located on the side of the first flap.
  • the double fold lines are biased from the end of the second fold line located on the side opposite the second flap, the bias side of said second flap being located on the side opposite the first Rabat.
  • the blank consists of two identical half blanks, interconnected by end tabs by gluing.
  • the second trapezoidal flaps are rectangular.
  • Figure 1 is a schematic view, in perspective, of the first three stages of the crate formation from two half blanks according to a first embodiment of the invention.
  • Figure 2 is a perspective view of the steps following of the embodiment of the invention more particularly described here.
  • Figure 3 is a plan view of two half blanks according to the embodiment of the invention more particularly described.
  • Figures 1 and 2 show in perspective the steps in the process of manufacturing a case, from two identical half-blanks 2, 2 'of cardboard double-sided corrugated, for example 3 mm thick and large dimensions, for example from 1,200 x 1,000 x 1,200 mm.
  • Each half blank has two flaps rectangular, namely a first flap 3, 3 'and a second flap 4, 4 ', interconnected by a first fold line 5, 5 ', and connected to a set of flaps with second fold lines 6, 6 ', perpendicular to the first lines 5, 5 ', namely a first flap 7, 7 ', connected to the first flap 3, 3' and a second flap 8, 8 'connected to the second flap 4, 4'.
  • the first flap 7, 7 ' is substantially rectangular and has a double line of folding 9, 9 'at an angle forming an end portion triangular 10, 10 'with one of the angles located on the second fold line 6, 6 '.
  • the second flap 8 of the half blank 2 is shaped substantially trapezoidal and has an edge or side at an angle 11, symmetrical about the extension of the first fold line 5, with the double fold line 9 of the adjacent flap.
  • the half blank also has a tongue collage 12, connected to the lateral side of the first flap, parallel to the first fold line.
  • the first blank 2 is flat and for example placed automatically or manually on a work surface 13 in a position determined by stops (not represented).
  • the top of the tongue 12 is then glued by first means of gluing (not represented).
  • These means include for example a pistol glue or liquid glue applicator under pressure, in the form of three fine cords parallel, all along the tongue, connected from way known in itself to a reservoir of preparation and storage of liquid glue.
  • the second blank 2 ' is then deposited so automatic and precise on the tongue 12, the edge end 14 'of the blank 2' superimposed parallel and precisely to said tongue 12.
  • the blank 2 'can for example be laid on support rails in a plane 17 a little higher than plane 13, with wedging in one position determined as for half blank 2, the application then by vertical lifting of the plane 13 (arrow F in figure 1) until contact between edge and tongue.
  • the tongue and the edge are then pressed one against each other to make the collage, thanks to example to a retractable counter blade (not shown) to form the assembly 15 of the figure 1, equivalent to a four-part blank made of single piece, to which the method of the invention is also perfectly applicable.
  • the blank thus reconstituted and glued is then brought into the folding position 16.
  • the blank is for example slipped horizontally on guide rails and lateral supports (not shown) located in the plan 17, until the flaps 3 'and 4 are in face of folding means (not shown).
  • the positioning accuracy of the half blanks laterally and longitudinally with respect to folding device can be approximate, by example to one or more millimeters.
  • the lateral stops of the guide rails allow effect a certain play to avoid friction important and authorize the prior sliding to the folding station.
  • Glue lines on elements 12 ', 10 and 10 ' can also be applied during travel to planned locations so programmed.
  • Folding is achieved by folding arms belonging to a mobile crew (not shown) of way known in itself.
  • the tongue 12 ' is applied precisely on the end edge 14 of the flap 4 to form the blank 18 folded on itself (see figure 2).
  • the flaps 7, 7 ', 8, 8' are then in a position entirely directed towards outside the shutters, in the plan and in the extension of said components.
  • the blank thus folded up is then ejected when the next blank arrives for example directly on a pallet. He is then ready to storage and / or transport.
  • the body thus unfolded is advantageously fixed on a wooden pallet, for example by stapling the flaps on the wooden crosspieces of the pallet.
  • Figure 3 shows two half blanks 2, 2 ' identical, in double-sided corrugated cardboard.
  • each blank 2 has two components rectangular 3 and 4, namely a first flap rectangular, for example square, 3 and a second rectangular flap 4, of smaller width, and connected to one side of the first flap by a first fold line 5.
  • the half blank also has a tongue end 12 connected to the other side of the first flap 3 by a fold line parallel to the first fold line 5.
  • Each flap 3 and 4 has a flap, namely a first substantially rectangular flap 7 connected to the first part by a first second line of folding 6, and a second flap 8 connected to the second flap by a second second fold line 6 aligned with the first second fold line 6.
  • the first flap 7 includes a double line of folding 9, consisting of two folding lines simple, parallel, spaced from each other by distance e, equal to or substantially equal to the thickness corrugated cardboard at an angle from the end 61 of the second fold line 6, on the side of the second flap 8, at a determined angle ⁇ with said second fold line.
  • the angle ⁇ is equal or substantially equal to 45 °.
  • the groove of the grooves formed by these folds double is also located on the same side as the groove in the groove of the second fold line, relative to the plane of the flap.
  • the first flap 7 also includes two lateral sides 71 and 72, free, slightly biased towards inside the flaps, for easy assembly.
  • the second flap 8 has a side or angled edge 11 from common end 61 between the second fold lines, also according to the angle a with respect to the second fold line 6.
  • edge 11 is symmetrical by compared to the extension 5a of the first line of folding 5, with the double folding line 9 of the flap adjacent.
  • the other side 81 located opposite the first flap is for example perpendicular, at least in part on the side of the second fold line, with said second fold line 6.
