Slivers are first fed to the device in large cans and subsequently exposed to weight and tension through a series of rollers before being passed through flyers which create a twist in the fiber strands; slivers are thus converted to thin roving, which is then fed into a ring frame for futher processing. Used as an intermediate step between the draw and ring frames, these devices strengthen the roving and prevent breakage during future processing.  ]]></termNote><termCreatedDate>2026-03-30 20:53:46</termCreatedDate><relation><relationType>UF</relationType><termId>31482320</termId><termName>roving frame</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31482321</termId><termName>simplex frame</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31422156</termId><termName>simplex machine</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31482322</termId><termName>speed frame</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31422254</termId><termName>textile machines</termName><termType>PT</termType></relation></term>  </Zthes>
