FORMING DEVICE, MACHINE, PACKAGING LAMINATE WEB, FORMING METHOD AND PROCESS IN PRODUCING PACKAGES

摘要

A forming device and method for use in a packaging machine of the type where packages are produced from a tube. The forming device (22a, 22b, 22c) com­pri­ses two oppo­­sing sealing elements (58, 60) between which the tube is arranged to be flat-laid and squeezed to heat the thermoplastic and obtain a first trans­verse seal of the tube. It further comprises two volume control elements (28, 30). The for­ming device is characterized in that it is arranged to displace the first trans­verse seal off-center in relation a longitudinal axis (64) of the first portion of the tube in a displacement direc­tion (D) essentially perpendicu­lar to the first transverse seal to enable later shaping of a correspon­ding final package (40) with a wall (41) arran­ged with a predetermined angle of inclination (ß) in relation to the displacement direction. The invention also relates to a machine, a process and a packaging laminate.
