Abstract (en)
[origin: EP2009163A1] The apparatus has a unit for supplying cool process air to a cooling chamber (2) to cool a set of filaments as they pass downwards through the cooling chamber. A laterally closed stretching unit (5) downstream of the cooling chamber has laterally closed side walls that have downwardly diverging portions. A connecting region between the stretching unit and the cooling chamber excludes access of air from outside to the filaments as they pass from the cooling chamber to the stretching unit, where the filaments drop from the stretching unit into a deposition belt (15).
