Abstract (en)
[origin: EP1169927A2] The method advances tow (2) pinched between upstream side pinch rollers (8,10) and downstream side pinch rollers (14,16) to provide a stretching force to the tow (2). Air extraction is made from the lateral sides of the tow (2) by air extraction nozzle (24,26) arranged on lateral ends of downstream rollers (14,16). An Independent claim is also included for running filter material filament tow manipulation apparatus.
