Claims (12)

A method of operating a machine for producing a sealed package for a product, comprising:
The sealed package (2; 102) advances the sheet-like packaging material (1; 101) along the traveling direction (F1) and elongates the sheet-like packaging material (1; 101) to form a continuous tube. By sealing and cutting the tube in a direction transverse to the direction of travel (F1) in order to obtain a respective pre-sealed packaging unit (200) filled with the product from the tube in the direction of closure. Manufactured,
Changing the configuration of the machine that was manufacturing the package (2) having the first structure so as to enable manufacturing the package (102) having the second structure; The first structure is different from the second structure in that the package (2) having the first structure includes a first basic unit (3) having a length (L) and a width (W). The package (102) manufactured from the first sheet-like packaging material (1) including the second structure has the length (L) and the width (W) of the first basic unit (3), respectively. ) Is manufactured from a second sheet-like packaging material (101) comprising a second basic unit (103) having a length (L) and a width (W) equal to said first basic unit (3) and said first basic unit (3). The second basic unit (103) Different respective crease patterns each other; having (20 120), the method.   The method of claim 1, wherein the package (2) having the first structure has a shape different from the shape of the package (102) having the second structure.   The method according to claim 1 or 2, wherein the package (2) having the first structure has a different capacity than a capacity of the package (102) having the second structure. The package (2) having the first structure has at least a first end cross section, the package (102) having the second structure has at least a second end cross section, The first end section and the second end section are perpendicular to a main dimension of the corresponding package (2, 102), the first end section and the second end section. have the same length dimension (W1, D1), the method according to any one of claims 1-3. The package (2) having the first structure has at least a first longitudinal boundary, and the package (102) having the second structure has at least a second longitudinal boundary. has the first longitudinal border zone and the second longitudinal border zone have different respective shapes, the method according to any one of claims 1-4. The method according to claim 5 , wherein the first longitudinal border comprises a straight longitudinal edge (51; 52; 53). The second longitudinal boundary defines a corner panel (81; 82) disposed between a side wall (149; 150) and a front wall (147) of the package (102) having the second structure. comprising a method according to claim 5 or 6. The corner panels (81; 82) are arranged along two fold lines (90, 91; 92, 93) extending between common points (P2, Q2; P3, Q3). 8. The method according to claim 7 , wherein the two boundaries (83, 84; 85, 86) are obtained by folding each of the first and second (103). The method according to claim 8 , wherein the two fold lines (90, 91; 92, 93) each have a concave shape, each concave surface facing each other. One of each of the two fold lines (90, 91; 92, 93) is a curved fold line, a fold line defined by a series of at least two straight fold segments, a curved fold line and a straight line. The method according to claim 8 or 9 , wherein the method is selected from the group comprising a combination of fold segments. Said traveling direction (F1), the parallel to the length (L) of the first basic unit (3) or said second base unit (103), in any one of claims 1 to 10 The described method. The first sheet-like packaging material (1) or the second sheet-like packaging material (101) is advanced along the advancing direction (F1) by at least a pair of gripping jaws, one of the claims 1 to 11 the method according to one paragraph or.
