A tube arrangement (1) comprises two tubes (2, 3) and a common separation wall (4) between these tubes and is formed of elongated cloths of a heat-sealable material. Each flap (2A', 3A', 4A'; 2B", 3B', 4B') provided at each longitudinal edge of the three elongated cloths - for the two tubes (2, 3) and the separation wall (4) - is heat sealed to an edge portion (2A, 3A, 4A; 2B, 3B, 4B) of another cloth for forming two cloth layers in each part of the joint. <IMAGE> |
