Open=end rotor spinning unit - has false twist provided by a ring on the end of the opening roller shaft which is more compact and saves energy

摘要

Yarn is withdrawn from an open end rotor spinning unit by means of a funnel and tubular guides, with an interposed rotary false twist device, driven from the opening roller shaft. The output tubular guide has adjustable positioning, so that the distance to the false twist device does not exceed the average staple fibre length. ADVANTAGE - The false twist device driven by the opening roller shaft is more compact and saves energy
