摘要： The yarn feed apparatus (1) at a textile machine, to give a positive yarn (2) feed, has a yarn feed wheel (17) on a carrier (4) which rotates round an axis (D) through a rotary drive (18). The wheel (17) has a yarn entry zone, yarn storage zone (26) and a yarn exit zone (36). The yarn exit zone (36) has a circular cross section. The cross section of the yarn storage zone (26) deviates from a concentric circle round the axis (D), at least in sections. The yarn entry zone has a solid surface, forming a concentric circle round the axis (D) at each point. The entry zone surface has a conical tapering towards the yarn storage zone (26) with the conical surface at an angle of ≥ 60 degrees to the axis (D) and preferably 75 degrees . The yarn exit zone (36) has a closed surface, forming a concentric circle to the axis (D) at each point, as an expanding cone away from the storage zone (26). Or the surface can be a curved surface on a torus with a curvature radius smaller than the radius of the feed wheel (17). The yarn storage zone (26), between the entry and exit (36) zones, has a solid surface with a polygon cross section concentric to the axis (D) at each point with straight edges or edges which are not straight. The cross section of the yarn storage zone (26) is defined radially outwards by preferably rounded laying sections, with the yarn storage zone (26) radially inwards between them as convex or concave curved or flat sections. The yarn delivery wheel (17) is in one piece with a shaft, wholly of ceramic, sapphire, quartz, a material with a diamond content, nitride or carbide. Or it has a basic body of metal and preferably aluminum. The metal body can be cladded with a coating containing oxygen and a component which differs from the material of the body. The yarn feed wheel (17) can have a wall at one end side with a center drilling for preferably a shaft to hold the wheel directly.

摘要： The invention relates to a yarn feeder (1) which comprises a yarn feeding wheel which is preferably made of a ceramic material or coated with an equivalent substance. Owing to the materials used and/or its shape the yarn feeding wheel presents improved continuous service properties. Said shape and/or material are highly wear-resistant. This is achieved by ceramic surfaces and/or the combination of a conical, continuous yarn inlet surface (24) with strip-shaped support surfaces (25) contiguous thereto in the yarn storage area (26), and a continuous, i.e. uninterrupted, surface in the yarn outlet area. The surfaces are configured such that on its way from the inlet area to the outlet area the yarn moves across the corresponding surfaces (24 , 25, 36) along its entire axial path. The strip-shaped bearing or support surface for the yarn (2) in the yarn storage area is obtained by shaping the yarn feeding wheel (17) accordingly in said yarn storage area. Openings or slits or such like in the yarn feeding wheel are not required but can be provided for.

摘要： The tensioner (15) extends and tensions the thread to a set degree. The thread is wound a few times round the motor-driven feed wheel (16). At the feed wheel, leading tension does not influence trailing tension. The motor (17) feeds thread solely in accordance with thread demand. Its control is independent of the tensioner itself, and of tension arising in the section after the feed wheel. An Independent claim is included for the corresponding method of feed control. Preferred features: In one variant, the tensioner is a thread brake operating independently of thread speed. The sensor (24) measures tension between tensioner and feed wheel, adjusting braking accordingly. The friction brake used, has fixed or adjustable loading. An electrically controlled actuator operates it. A belt brake is employed, the controller (18) adjusting wrapping angle through an electrical actuator. Further variants, based on the foregoing principles, are described. The method provides that, following withdrawal from the supply spool, extension is such that no increase in tension causes further reversible extension.

摘要： The tension in the yarn (7) is measured by the force exerted on a guide peg (21). An actuator can move two further pegs (42,43) into the yarn path to lift the yarn off the measuring peg (21) to calibrate the zero position on the transducer. Independent claims are also included for the following: a) A yarn feeder for knitting machines with strongly variable yarn requirements, having a yarn delivery wheel (4) driven by a motor controlled by the claimed yarn tension sensor to provide constant feed tension. b) Analyzing the tension signal to detect periods when the tension can vary from the set value (e.g. during the carriage return on the knitting machine) and initiating the actuator to lift the yarn off the measuring peg, reset the zero and replace the yarn on the peg.
