Abstract
A false-twist device comprises two axially parallel rollers rotatable about their axis for supporting a twist tube in the cuneal throat formed thereby, driving means for simultaneously driving the rollers, at least one yarn deviating element for feeding a yarn end to, or removing it from, the twist tube at a predetermined angle relatively to the tube axis, and means for holding the tube in place when no yarn is present in the tube.
Claims19
Device for false-twist texturing of yarns, comprising two axially parallel rollers which are rotatable about their respective axes and at least one twist tube supported within a throat formed by the fllers and in tangential contact therewith, driving means for simultaneously driving the two rollers, yarn deviating means for feeding the yarn to the twist tube and removing it from the same at a predetermined angle so that the twist tube is pressed against the rollers by means of the force of the yarn tension and means for maintaining the position of the twist tube relative to the rollers when no yarn is present in the twist tube.
Device for false-twist texturing of yarns comprising two axially parallel rollers which are rotatable about their respective axes and at least one twist tube supported within a throat formed by the rollers in tangential contact therewith, yarn deviating means including an element for feeding the yarn to the twist tube at a predetermined angle, said element being a stationary roller or a pin and an element for removing the yarn from the twist tube at a predetermined angle, said element being a roller rotatable about its axis, whereby pressing of the twist tube against the rollers by means of the force of yarn tension is achieved, and means for maintaining the position of the twist tube relative to the rollers when no yarn is present in the twist tube.
Device for false-twist texturing of yarns, comprising two axially parallel rollers which are rotatable about their respective axes and at least one twist tube supported within a throat formed by the rollers and in tangential contact therewith, driving means for simultaneously driving the two rollers, said rollers having different diameters and said driving means driving the rollers so that the roller with the larger diameter is effective to urge the twist tube into the cuneal throat between the rollers, yarn deviating means for guiding the yarn to the twist tube and removing it from the same at a predetermined angle so that the twist tube is pressed against the rollers by means of the force of the yarn tension and means for maintaining the position of the twist tube relative to the rollers when no yarn is present in the twist tube.
