PCT No. PCT/SE91/00274 Sec. 371 Date Nov. 24, 1992 Sec. 102(e) Date Nov. 24, 1992 PCT Filed Apr. 17, 1991 PCT Pub. No. WO91/16483 PCT Pub. Date Oct. 31, 1991.A thread feeding system including a thread regulator having a fixed housing, a hollow rotatable shaft extending through the fixed housing, a rotatable winding section secured to the rotatable shaft, an angled thread duct extending through the thread regulator, an inlet positioned at an upstream end of the duct, and ejectors positioned along the duct portions. The ejectors supply a working medium from a pressurized working medium source to the duct to facilitate threading of a thread through the thread duct. The inlet receives a free end of the thread from a thread spool assembly positioned upstream from the thread regulator. The feeding system also includes an arrangement for controlling the ejectors so that the ejectors generate a pressure proximate to the inlet to develop a flow of the working medium into the inlet, and an arrangement for feeding the thread through the thread regulator in a pulsating manner to insure that the free end of the thread passes unobstructed through the thread duct.
