High speed yarn twister with fluid propelled yarn guide

A device for twisting filamentary yarn comprising:

• a housing defining a cylindrical interior region and an annular race surrounding said interior region;
• said housing having a pair of opposed parallel planar surfaces extending from said race to said interior region said surfaces defining therebetween a guide slot;
• and
• a follower having a base component received in said annular race for movement therealong in a selected orbital direction, a yarn guide component positioned in said interior region for receiving therein said filamentary yarn, and a planar support flange which radially extends from said follower base component through said slot and is joined to said guide component;
• wherein
• said race includes a pair of fluid inlet ports circumferentially spaced-apart substantially equidistantly relative to one another for introducing a pressurized fluid in a substantially tangential direction into the race to propel said base component in said orbital direction, said introduced pressurized fluid being discharged from said housing through said slot so as to provide a fluid bearing for said support flange of said follower.
