Description of the invention: [Technical field to which the invention pertains] The yarn is sent to a yarn in a manner that is used for active yarn transfer, that is, controlled yarn delivery, in a yarn feed amount. Yarn machine, yarn feeder of a knitting machine. [Prior Art] Active yarn feeders are known. For example, U.S. Patent No. 5,782,424 discloses an active yarn feeder having a carrier for attachment to a machine ring and a vertical shaft supported by the carrier (4), 10 A pulley is carried on the top and a feed pulley is carried on the bottom. A yarn brake is provided on the free end of the carrier, a yarn extending through the yarn brake to the yarn feed pulley and being wound on the yarn feed pulley for several weeks. A yarn input bobbin is provided on the yarn feed carousel, and the shuttle eye guides the yarn in a controlled manner on one of the conical narrow yarn input regions of the yarn feed roller. Between the yarn 15 is fed between the shuttle and the yarn brake, a yarn sensor lever applies a force to the yarn to test for the presence of a yarn. In the event of a yarn break, the yarn sensor core will fall down and generate a shutdown signal. A similar yarn sensor lever is provided on the output side behind the yarn feed pulley for monitoring the yarn traveling in the direction away from the yarn feed pulley. 20 Although these feeders have proven to be basically satisfactory and have become a benchmark, they require some degree of skill to penetrate the yarn, especially in yarn brakes, input sensors and inputs. The place of the eyes. Another type of yarn feeder is disclosed in U.S. Patent No. 3,922,887, the yarn feeder of which has a carrier, and a toothed pulley is rotatably supported on the carrier 1337633. A drive toothed belt is wound around the toothed pulley. A guide yarn is provided to guide the yarn onto the pulley. The yarn guide eye is height-adjustable for guiding the yarn under the toothed belt in a first position to convey the yarn in a non-slip or slight slip. In a second position 5, the yarn guide shuttle guides the yarn to the area of the toothed pulley that is not in contact with the toothed belt. In this case, the yarn slides on the upper surface of the pulley so that it does not actively advance. The yarn feeder is used in a rubbing operation. U.S. Patent No. 4,598,560 discloses a friction type yarn feeder having a carrier that supports a vertical rotatable shaft. The shaft has a pulley at the top and a plurality of friction wheels at the bottom. The yarn travels in a one-line winding friction wheel and contacts the friction wheel along one of the outer circumferences of the friction wheel. A cantilever lifts the yarn off the surface of the friction wheel. The position of the cantilever depends on the tension applied to the yarn by the yarn machine. Therefore, the friction feeder delivers the yarn only when and only when a tension is applied to the yarn by the yarn machine. • Although the yarn guide member that is movably supported is used to start and stop the yarn transfer in the case of the friction yarn feeder, in the case of the active yarn feeder, the yarn is guided in a controlled manner. To the input area of the yarn feed wheel, a single layer of coil is established. Then, the yarn running on the yarn feeding roller rolls the existing thread reel forward toward the ground. The yarn sensor element or other movably supported component is used to detect a yarn breakage in a timely manner so that the knitting machine can be shut down before the broken end runs into the machine. An active yarn feeder is disclosed in U.S. Patent No. 4,399,952, which is incorporated herein by reference. The two cages are arranged at an oblique angle to each other to provide one of the yarn rolls for feeding. It has a storage drum from which the yarn is known by rotating the drum or by a further storage yarn, which is pulled in the axial direction. The wire winding device reaches the drum. '5 SUMMARY OF THE INVENTION The object of the present invention is to improve the characteristics defined by the yarn feeder described above. This object is achieved by a yarn feeder comprising the first one of the patent application. 10 In the case of the yarn feeding according to the present invention, it is an active yarn feeder or a yarn feeder. The yarn-discreting positive yarn feeder has a yarn feeding roller, and the yarn to be conveyed is wound around the feeding roller, and the wheel is repeatedly made so that the amount of the conveyed yarn does correspond to the yarn feeding of the yarn feeding wheel. The shuttle eye is disposed on one side of the yarn feed wheel, and the m 4 heart-feeding wheel is provided above one of the yarn input areas. The yarn input region constructs a yarn input bevel, i.e., the diameter of the yarn feed pulley _ a portion that is significantly reduced from the shank to the top position to a position slightly below the axial direction. The yarn input zone can be considered to have a greater than 120. One - the conical part of the cone angle. Unlike a true conical structure having a circular cross section, the yarn input region may have a polygonal cross section, and a plurality of independent sticks form a cage feed pulley. The line input zone is for providing a slow, axially slidable movement of the yarn roll as the yarn feed wheel rotates. The yarn feeder is provided with a yarn feed pulley which can be formed by an enclosed body or a side. The yarn coil is wound around the yarn feed roller a plurality of times. The yarn is fed into the shuttle through a yarn before reaching the yarn feed pulley. The shuttle eye and the feed pulley rotate relative to each other 1337633 to produce a coil. This movement is achieved, for example, by rotation of the yarn feed wheel relative to one of the yarn input eyes. Feeding of the yarn roll can be carried out by the shape of the yarn feed wheel or by a separate feed device. The yarn input shuttle is movably disposed with the restriction that the yarn to be traveled on the five yarn feed pulley is pivoted to a working position. In the event that the yarn has broken due to its breakage or because it has sagged for a significant degree for other reasons, the 'yarn input fuzzle will move to another position, which is detected by the sensing member and used to emit a Corresponding signal. The signal can be a switching signal or, for example, can be used to signal a fault condition and/or turn off a later connected machine such as a knitting machine. The yarn input shuttle is preferably held in a manner such that it moves in a vertical plane during movement from the working position I to a stop position u, the axis of rotation of the yarn feeding wheel being located in the vertical plane and The vertical plane extends radially from the axis of rotation. During this event, the yarn input 15 shuttle eye remains at least in the operative position and preferably remains in all of the intermediate positions and remains in the parked position above the yarn storage area of the yarn feed pulley. In the conventional yarn feeder, a yarn guide shuttle is provided on the input side in front of the yarn feed roller for guiding the yarn to the input area of the feed wheel, and also provides additional application on the yarn. Frictional yarn sensor lever. In the yarn feeder according to the present invention, the yarn sensor lever and the yarn input bobbin are combined into a movably supported member so that there is no such thing as a force applied to the yarn. In this way, it is possible to work with a very low yarn input tension that is smaller than the conventional yarn feeder. By virtue of the possibility of working with a very low yarn input tension, the yarn is less stressed and the wear occurring in the yarn guiding element is less than 1 1337633. By minimizing the amount of yarn deviation, the tension of the yarn in progress and its damage are reduced. For this reason, this trend has made the use of very fine yarns feasible. The movably supported yarn input shuttle is preferably oriented such that its axis ? 5 is radial to the axis of rotation of the yarn feed pulley. In this way, its function ^ is independent of the direction of rotation of the yarn feed wheel. - The yarn feed roller of the yarn feeder according to the present invention may be driven by a motor at a constant or variable revolutions per minute (rpm) or by a belt. By inputting the rotatably supported yarn into the shuttle eye, it is in principle possible to monitor the yarn tension. According to a preferred embodiment of the present invention, the yarn input fuzzing is used only to monitor a yarn breakage, i.e., it only monitors the presence of the yarn. For this reason, the yarn input eyelet is held by the yarn against a fixed pedestal, preferably at a position (working position) close to the yarn feeding wheel. After the yarn breaks, the yarn input shuttle can be removed from the yarn feed pulley (stop position). At the same time, a preferred pivoting motion is performed. The path of the movement of the yarn into the eyelet is preferably selected as described above such that the yarn is fed into the eye at all end positions and at the intermediate position at the height of the yarn input area of the yarn feed wheel. Or above. In this way, it is ensured that the yarn is always wound on the delivery 20 yarn in a well-ordered manner even if the yarn input shuttle is temporarily turned out of its working position' and does not occur here. The overlap of the line volumes. The yarn input shuttle is preferably carried by a pivot lever that is movably supported at one end, and the yarn input shuttle is disposed or formed at the other end of the lever. Preferably, the pivoting lever pivots about an axis above the upper rim of the yarn feed wheel. Moreover, the axis is preferably oriented away from the feed pulley
