| 摘要 |
The invention relates to a method for joining an initial section of a strip-type tubular film (2) to an end section (4) of a second tubular film (5) extending in an at least partially strip-type manner over successive processing stations, especially a sacking installation. According to said method, at least one foldable tongue (3a, 3b, 4a, 4b) is formed by cutting the initial and end sections (3, 4) of the two flexible tubes (2, 5) to be joined, applying a tongue (4a, 4b) of the end section (4) to a tongue (3a, 3b) of the initial section (3), and joining the superimposed tongues (3a, 3b, 4a, 4b) in a tension-proof manner. The initial and end sections (3, 4) of the tubular films (2, 5) are joined in a tension-proof manner by means of welding which is preferably carried out by means of ultrasound. |
