DEVICE FOR INDIVIDUAL CONTROL OF YARN GUIDING MEANS

摘要

A device for individual control of the oscillating motions of sinkers, healds, needles or similar yarn guiding means (4) in high-speed textile machines, for instance yarn guiding means in a shedding machine, a plurality of yarn guiding means which are axially displaceably controlled and adapted to be imparted an oscillatory motion by operating means (A, B) being disengageable by means of the control device from such motion in predeterminable positions during a predeterminable period of a work cycle. The novel features of the invention reside in that each of the yarn guiding means (4) is connected to an individually actuable control means (1) adapted, upon actuation, to act on the motional dependence of the yarn guiding means on the operating means, that the yarn guiding means (4) are provided, at least at one end thereof, with end portions or extensions (4a) which are passed in groups through guide plates (3) transversely displaceable towards and away from each other, and that the end portions (4a) of the yarn guiding means (4), which end portions are spreadable beyond the respective guide plate by guide means (2) substantially into a fan or cascade shape, have means for cooperating each with a respective control means.
