The invention relates to a device for producing packages (2) from an M-folded material web (3), comprising a rotatable tool holder (4) supporting a plurality of peripherally arranged tools (5). The tools (5) each comprise a base element (6) and an engagement element (7) which is arranged such that it is pivotable relative to this base element, which base elements (6) form a circumferential outer surface (8) of the tool holder (4), over which circumferential outer surface (8) the said material web (3) can be passed. The tool holder (4) is arranged, upon rotation, to move the tools (5) along a work path (WP) along which they can be brought into engagement with the material web (3) by lowering of the said engagement element (7) for the connection of mutually facing wall portions of the material web (3) along connecting portions (10) which define the said packages (2), and a return path (RP) along which the tools (5) can be brought out of engagement with the material web (3) by raising of the said engagement element (7). Each tool (5) is arranged to be moved together with the material web (3) when it is moved along the said work path (WP), and each tool, when engaging with the said material web (3), is arranged to participate in the production of at least two packages (2). Each pair of adjacent tools (5) are arranged for the joint production of one package (2). The invention also relates to a filling machine which is arranged to fill a package produced in such a device. |
