发明名称 Method for changing rolls of tubular film
摘要 A method for joining an initial section (3) of a film tube (2) which is wound up in a band-like manner on a reel (1) with an end section (4) of a second film tube (5) extending over subsequent processing stations, especially a packaging system, in an at least partly band-like manner, with the band-like initial and end section (3, 4) each having two mutually superimposed outer lateral surfaces (10, 11, 15, 16) which each converge in their boundary regions into two interposed, inwardly folded inner lateral surfaces (17, 18, 19, 20) which thus form an inwardly situated fold axis (S, T). It is provided for in accordance with the invention that in the two outer boundary regions of the initial or end section (3, 4) a tab (7, 27) each is formed by placing a cut, which tab is joined in a tension-proof manner with the opposite section (3, 4), with the initial section (3) overlapping the end section (4).
