Abstract
An open end yarn spinning apparatus having a hollow opening roller for feeding fibres to a collecting surface formed in a rotor, the curved wall of the roller being such as to permit gaseous flow from inside the roller to outside the roller, and a rotatable impeller arranged to produce a positive gas pressure within the hollow roller during operation of the apparatus to cause a gaseous flow to pass from inside the roller to outside the roller, said impeller being mounted so as to be constrained to rotate with another member of the apparatus that rotates in operation of the apparatus.
Claims7
An open end yarn spinning apparatus comprising in combination:
- a hollow cylindrical opening roller adapted to feed fibres to a fibre collecting surface having the peripheral wall thereof formed such as to permit gaseous flow from inside the roller to outside the roller;
- and impeller means rotatable with the apparatus for producing a positive gas pressure within said roller during operation of the apparatus to cause a gaseous flow to pass from inside the roller to outside the roller through said peripheral wall.
