A method and a device for manufacturing a continuous bag-like package blank (24), which is produced by a plane plastic sheet (18) being unwound from a storage reel (19) of the sheet (18), the sheet being conveyed through an edge thickening equipment (1) and further to a folding device, to a welding device and to a slotting tool to obtain a continuous bag-like package blank (24), which, e.g., may be introduced into channels intended therefore in support arms in a packing machine, wherein the edge thickening equipment (1) comprises a process bed (17) over which the sheet (18) is conveyed, and that an extruder device (12, 13) having a first extruder nozzle (15) placed on the opposite side of the sheet (18) in relation to the process bed (17) is aligned and continuously extrudes a material bead (28) that is permanently attached to a first edge area (26) of the sheet, and that the extruder device (12, 13) comprises a second extruder nozzle (16) placed on the opposite side of the sheet (18) in relation to the process bed (17) is aligned and continuously extrudes a material bead (28) that is permanently attached to a second edge area (27) of the sheet (18) opposite the first edge area (26). |
