Title: Automatic texturising jet threading method - comprises laying yarn components across jet entry in threading position and connecting to suction for standing, etc.
Inventor: GEIRHOS JOSEF
IPC: D02G1/02
Filed: 1991-06-19
Abstract: To thread a number of yarns automatically into a texturising jet, where they travel in the same direction and at different speeds, the texturising jet is brought into the threading position (A) while maintaining the jet axis line, for its outlet end to be connected to a suction system to generate underpressure within the jet. A yarn is moved across the jet entry opening on a defined yarn path and is cut after the jet entry opening. The yarn is drawn into the jet entry through the underpressure within the jet. A further yarn is similarly moved, to intersect with the first yarn before the jet entry opening, to pass together through the jet entry without contact and parallel to each other through the leading section of the jet channel in front of the eddy zone. After the yarns have entered the jet it is returned to the texturising position (B) while maintaining the jet axis line. The yarns are cut between the jet outlet and the suction unit, and the projecting yarns are picked up by a mobile suction unit to be positioned at the outlet side of the texturising jet in the texturising position. ADVANTAGE - Allows the components of effect yarns to be threaded into the texturising jet assembly, where the standing and effect elements travel at different speeds, without excessive tension.
