FIELD: packing industry.
SUBSTANCE: moulding device comprises two oppositely arranged sealing elements, between which there is a pipe laid horizontally and compressed to heat thermoplastic and to produce the first transverse seam of the pipe and two elements to control volume arranged on the opposite sides of the pipe in the open condition, in which the pipe moves relative to the elements of volume control, and in fixing position to give the specified shape to the pipe at the first section between the first transverse seam and subsequent second transverse seam of the pipe. Device provides for displacement of the first transverse seam from the centre relative to the longitudinal axis of the first pipe section in direction of displacement, practically perpendicularly to the first transverse seam with subsequent moulding of the appropriate finished package with a wall that has the specified angle of inclination to the displacement direction. The packaging laminate fabric to form a pipe by means of a moulding device comprises a folding template, corresponding to one unit of a package and repeating itself along the fabric. The folding template comprises a front fold, which determines the length of the front wall in longitudinal direction of the package, directed towards the upper wall and parallel to the longitudinal axis of the first pipe section, back folding line that determines the length of a back in longitudinal direction, the first side folding line that determines the length of the first side wall in longitudinal direction and the second side folding line, which determines the length of the second side wall in the longitudinal direction, in which the first and second side folding lines are inclined in the transverse direction of the fabric. A machine is also presented to produce packages, comprising a moulding device, according to invention, there is also a method to shape packages on this machine and a process of packages production, which includes the method of packages shaping.
EFFECT: improved efficiency and stability in stock-keeping.
