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.  ]]></note></mads>
