hollow fiber membranes 20 the resulting hollow fiber membranes 20 are then transported to a rinsing zone 16 and are transported through rinsing baths via transport rollers 14 15 at the first removal speed v 1 the hollow fiber membranes 20 are then further conducted to a drying zone 25 including drying chambers tk 1 tk 6 in which the hollow fiber membranes 20 are dried and elongated by 5 to 10 or 10 to 20 as shown in fig2 the hollow fiber membranes 20 within the last drying chamber tk 6 are transported through a curler 40 including curler rollers 42 44 having the same construction two rollers 50 52 are located external to the drying chamber tk 6 for removing the hollow fiber membranes 20 from the drying chamber tk 6 a roller 26 that is located upstream of the curler rollers 42 44 and used to convey the hollow fiber membranes 20 into the nip formed between the curler rollers 42 44 runs at a removal speed of approximately 410 mm s while a roller 27 that is located downstream of the curler rollers 42 44 and used to facilitate removal of the hollow fiber membranes 20 from the nip formed between the curler rollers 42 44 runs at a removal speed of approximately 415 mm s due to the differing speeds of the rollers 26 27 the hollow fiber membranes 20 are elongated by approximately.
