摘要:
A method (S100) for producing a web (118) of packaging material is disclosed. The method (S100) comprises providing (S102) a carton-based web provided with a first side (120) and a second side (122), and printing (S104) décors (200a-b) on the first side (120) of the carton-based web by using a printing plate cylinder (112) having at least two subsequently placed printing plates (114a-d) attached thereto, wherein the at least two printing plates (114a-d) have different printing patterns (202a-b) such that sequences (206a-b) of sections (204a-c) of the web (118) with different décors (200a-b) are provided, wherein each section of the web (118) is arranged to be transformed into a package (500) filled with food product in a roll-fed filling machine (600).
摘要:
There is described a packaging machine (1) for producing sealed packages (2) of a pourable food product from a strip (6) of heat-seal sheet packaging material. The packaging machine (1) has a number of photocells (14), which are programmable externally as regards their setting parameters, are positioned facing the strip (6) of packaging material to detect optically detectable elements on the strip, and have setting means (26, 210, 300). The packaging machine (1) also has a control unit (16) connected to the photocells (14) and having enabling means (24) for enabling the setting means of a specific photocell (14), data downloading means (26, 240, 310) for downloading off the specific photocell (14) the setting parameters of the photocell, and data uploading means (26, 260, 330) for uploading onto the other photocells (14) setting parameters calculated as a function of the setting parameters downloaded off the specific photocell (14).
