Abstract: The invention relates to a device (1) and a method for preparing a packaging box (2, 74) from at least one storage location (3) for a stack (4, 68, 69) of corrugated cardboard cut-outs, including means (6) for moving the stack forward while same is being unstacked and means (7) for unstacking the cut-outs by means of suction. Since the cut-outs are stacked vertically, the means (6) for moving the stack forward comprise a plate (8) for lifting the stack vertically up to an engagement plane (9) for the cut-out (28) located on top. The device comprises means (27) for locating the X, Y, Z position (pi) of the top cut-out in the storage location and means (29) for calculating the X, Y, Z path, comprising a vertical component, and means for unstacking on the basis of said position (pi), which are designed to control the movement of said unstacking means between a position (9) for grasping the cut-out and a position for positioning same a predetermined work station likewise located at X, Y, Z.

Abstract: The invention relates to a set (22) of blanks for forming a packaging box, a method and a corresponding box. The set includes two corrugated board blanks, namely: a first blank (2?) including flaps connected to one another by first fold lines (9?), one side of said blank having no folds; and a second blank (12?) including panels (13?, 14?, 15?, 16?) connected to one another by third fold lines (19?), the panels of the second blank being stacked respectively on the part of the first blank having no folds. Two non-adjacent flaps (3?, 5?) of the first blank are glued to two respective facing panels (13?, 15?) of the second blank, thereby preventing the relative movement thereof during folding or during the formation of the box when the blanks are wound around a volume having pre-determined dimensions.

Abstract: This is a method and device for making a packaging box from two blanks (2, 3), wherein blanks are taken simultaneously from two adjacent stacks (25, 26) and placed on two parallel tracks (29, 30), the blanks are transferred flat until butted longitudinally to an assembly station, the first blank is glued on its way to the longitudinal abutment position, the first and second blanks are butted laterally into their respective positions to give them an exact lateral reference position, they are grasped, and transferred laterally, and the second blank is placed on the first blank which is thus indexed, escaping the drivers (61) of the first track (29) when the second blank is placed against the fast blank, but clamped by vertical pressure. The second blank is then applied to the first blank to glue them together in their respective defined longitudinal positions, and the resulting set of blanks is then transferred to an erecting station where the box is erected by rolling the blanks around a core.

Abstract: A device and method for calculating the work load of an engine more efficiently and accurately. The device for calculating the work load of an engine comprises a means for determining a desired frequency component to calculate the work load of the engine obtained through frequency decomposition of the volume variation rate of the engine. The device further comprises a first calculating means for calculating a first correlation coefficient between the volume variation rate and a reference signal composed of a frequency corresponding to the determined component, and a second calculating means for calculating a second correlation coefficient between the cylinder inner pressure of the engine and a reference signal composed of a frequency corresponding to the determined component. The work load of the engine is calculated using the first and second correlation coefficients.

Abstract: Machine (1) and method of manufacture of a single-face corrugated board sheet whereby a fluted cardboard sheet (23) is glued to a flat sheet. The machine comprises three heating cylinders having parallel axes, tangently arranged pairwise and means (26) for positive traction driving the corrugated board sheet, said means being located downstream of the path of the corrugated board in relation to the three cylinders. The fluted sheet is pressed onto the cylinder downstream of the first contact (29) between the flat sheet and the fluted sheet, in an arc of a circle corresponding to an angle at the center (alpha) of a first predetermined value greater then zero. Said positive driving means are associated with complementary means for heating said corrugated board.
