Method of and apparatus for manipulating tows of filter material for tobacco smoke |
摘要 |
A tow of filamentary filter material for tobacco smoke is stretched between an upstream pair and a downstream pair of advancing rolls. Suction nozzles are provided to evacuate air from those portions of the path for the tow which are located immediately upstream and immediately downstream of the path section at the nip of the downstream advancing rolls. This prevents eddying of air at the nip and a fluttering of filaments of the tow.
