摘要： The inventive bearing system consists of a bearing seat (21), a roller bearing (18), and a squeezing element (26). The squeezing element lies flatly on the outer ring of the roller bearing and only in areas on corresponding areas of the bearing seat. The areas are preferably linear or strip-shaped and are oriented in an essentially axial manner. This facilitates the insertion and removal of the roller bearing (18) into or out of the bearing seat (21) and prevents the outer ring of the bearing from being rotated along, also in the case of bearing seats that are provided with relatively generous tolerances.

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 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： PCT No. PCT/DE96/01751 Sec. 371 Date Apr. 2, 1998 Sec. 102(e) Date Apr. 2, 1998 PCT Filed Sep. 17, 1996 PCT Pub. No. WO97/13906 PCT Pub. Date Apr. 17, 1997For supplying yarns, a yarn supply apparatus is contemplated that is designed particularly for knitting machines whose yarn demand fluctuates greatly over time. The yarn supply apparatus has a rotor-driven yarn wheel, which in the ideal case furnishes yarn directly to the knitting machine or its yarn guides without the interposition of yarn storage devices. The yarn tension is monitored by means of a yarn tension sensor, which provides measured value detection for a closed-loop controller that controls the supply by the yarn wheel. The controller is also embodied such that it can process signals that contain information about the future yarn demand. Thus in the event of imminent drastic changes in demand, of the kind that in flatbed knitting machines periodically occur at the edges of the knitted goods (turning points of the yarn guide), the controller can react by presupplying yarn or by ceasing to supply yarn. Yarn tension spikes and overly steep yarn tension drops can thus be compensated for. The controller may be designed such that it functions as a closed-loop status controller and intermittently as an open-loop controller. Other provisions, such as disturbance variable compensation, parameter adaptation, or the like, are possible.

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.

摘要： A yarn feeder device for feeding elastic (soft) yarns to a yarn consuming station whose yarn demand fluctuations over time has a control unit which ascertains the current yarn demand or to which the current yarn demand is reported. In accordance with this demand, a yarn feed wheel is driven at a rotary speed suitable for the yarn demand. The yarn travels via a tensioning device to the yarn feed wheel. The tensioning device is arranged such that the yarn is stretched in a defined way. As a result, a fixed association between a desired yarn feed quantity and the rotary speed of the yarn feed wheel is possible.
