Beschreibung
Zusammenfassung:	The method involves providing filaments with natural crimps, and guiding the filaments by a stretching unit and by a diffuser (5) in a connection. The filaments are isolated as crimped filaments on a storage device (4). The crimped filaments are supplied by the storage device of a hardening device (6), where the filaments are thermally hardened with the hot fluid by the hardening device. Additional non-crimped filaments are isolated at the storage device. An independent claim is also included for a device for manufacturing of a thick and/or voluminous spinning liner.
