Open=ended spinning rotor for yarn prodn. - has fibre feed channel directed into a slot formed in a projection from the cover to direct fibre to the edge of rotor cone
The machine has a fibre accummulation groove in the rotor and a conical interior leading to it, with a fibre feed channel narrowing towards the exit from the opening roller. The housing is connected to a suction tube, and has a projection contg. the yarn exit, as well as the mouth of the fibre feed channel. The narrowest cross-section of the fibre feed channel is a distance from the mouth which is constructed, as a slot, smaller at the top than the ideal cross-section of the channel. The ideal cross-section is the smallest possible circle. USE - The design enables small rotors to be effective in producing satisfactory yarn
