One or more tools (28) acting from the inside punch holes (42) at the seam (20). Before the return stroke, the tool is coated with glue and a force (40) is exerted in the transverse direction to widen the hole, the glue being transferred to the sheets at this point. The transverse force can be exerted from both sides and can intersect the fold line of the innermost sheet. At the seam, the article can be supported only at points clear of the hole to be formed. |
