Method and device for forming a continuous tubular foil (106, 308). Foil (106, 308) is supplied and buffered. Foil (106) is supplied as flattened tubular foil (106) from a supply. A next piece of foil (308) is supplied from a next supply. The ends of tubular foil (304, 309) are connected. This then allows supplying and buffering next tubular foil (308) supplied from the next supply. The device and method allow connecting the ends of tubular foils (304, 309) by opening the end (309) of the next flattened tubular foil (308) supplied from the next supply and moving the end of the flattened tubular foil (304) in an upstream direction (299) into the opened end of next tubular foil (309) from the next supply. Connection is made using a tape (250, 270) applied onto the foil ends (304, 309). |
