Abstract
A sliver opening apparatus for separating sliver into individual fibers for feeding of the individual fibers to the rotor of an open end spinning machine includes a rotating opening roller having a hollow interior and perforations from its exterior to its interior and air flow control elements disposed in the hollow interior of the opening roller. The air flow control elements define an opening located generally adjacent the sliver intake opening and an interior hollow chamber extending from the opening, the chamber being relatively large and the opening being relatively small. When the opening roller rotates, the air flow control elements cause the fibers from the incoming sliver to project toward the opening roller for optimum separation and combing by the teeth of the opening roller.
