摘要
To cut the hole in each pouch, the sheet material is shaped near the fold line, between two molding sections (15, 16). It is clamped in this position. A knife is advanced into one section (15), to meet a counter blade on the other (16). Preferred features: The shaping sections are curved about an axis perpendicular to the connection plane of the strips bordering the pouch. The blade (20) section carries a centering peg (21); the opposite section includes a matching guide bore (27). In the fold line of the band sections, an incision is stamped, forming a hole for passage of the (smaller) centering peg. At least one shaping section is heated. The hole center cut-out, is sucked away through a bore (28).
