Abstract (en)
A filament spinning installation conventionally comprises a cooling chute to receive filaments from a spinneret and a blower for directing a stream of cooling air across the path of movement of the filaments in the chute. The filaments are mutually spaced in an array until they have solidified to a degree permitting collection to a thread and contact with devices for further processing of the thread. In a chute according to the invention, at least one element is provided to lead air from a location in the vicinity of the filament array to the exterior of the chute by diverting the air flow into a direction transverse to the length of the chute.
