Abstract (en)
[origin: US4700539A] In an open-end spinning device with two friction rollers driven in the same direction, located next to each other and forming a spinning nip, at least one of such friction rollers has a perforated casing which is over-mounted at one end. Such roller further contains a suction insert with a suction orifice connected to a negative pressure (i.e. vacuum) source. The perforated casing is supported on a shaft, one end of which is received and supported in a portion of the suction insert. The suction insert is located within the casing, directly behind it, and has a constant cross-section up to its connection with a suction line. In such manner, a maximum suction cross-section is provided with minimum support requirements.
