(5) AERODYNAMIC EQUIPMENT OF A SPINNING MACHINE

one

The invention relates to the textile industry and can be used in the manufacture of yarn from natural, artificial fibers and their mixtures on ring spinning machines.

The twist produced by the spindle on the machine is distributed unevenly along the thread and monotonously decreases from the winding point on the cob to the clip of the exhaust cylinders of the machine's pull device due to the elastic component of the twisting deformation. The thread guide of the machine is an additional obstacle to the spread of twist to the clip of the exhaust cylinders. Therefore, the thread section between the spindle and the thread guide has a higher twist compared to the thread twist on the cob, and the thread section between the thread guide and the stretch device has a lower turn due to its accumulation at the thread guide and relaxation.

voltage, which reduces the strength of the yarn in this area. The bottom of the increase in the strength of the thread in the area between the thread guide and the exhaust device of the ring spinning machine is set to a reel, which allows to reduce the height of the torsion triangle and thereby increase the twist in this area.

The aerodynamic reel of the spinning machine is known, comprising a housing with a channel for feeding a gaseous agent into a cylindrical thread processing channel, made at an angle to the linear groove for threading, located along the thread processing channel and tangentially to it and made in its cross section on inlet tapering D 1.

Claims (3)

However, this reel does not provide sufficiently reliable locking of the filament in the channel for its treatment with a stream-gaseous agent and sufficiently 3. 9 exact thread contact with these threads for effective false twisting, which reduces the quality of thread processing and adversely affects the thread breakage. In addition, this reel does not allow high-quality curling of the thread without interrupting the supply of the agent to it. The purpose of the invention is to improve the quality of the thread and reduce its breakage. The goal is achieved by the fact that in an aerodynamic reel of a spinning machine, comprising a housing with a channel for supplying a gaseous agent to a cylindrical channel for thread processing, made at an angle to the straight line, a groove for threading the thread, and tangential to it and made tapering at the inlet cross section, the outlet of the gaseous agent supply channel communicates with the groove for threading at the groove portion before it enters the thread processing channel. The aerodynamic reel contains a plate thread guide pivotally mounted on the body with the possibility of overlapping for threading. In addition, the aerodynamic reel contains additionally several channels for supplying a gaseous agent, while the channels for supplying a gaseous agent are parallel to each other. The thread processing channel is widened at the ends. FIG. Figure 1 shows the layout of the reel on a ring spinning machine; in fig. 2 - reel with partial incision; in fig. 3 section aa in FIG. in fig. k-l is an embodiment of a channel for supplying a gaseous agent; in fig. 8 - section BB in Fig. 2. “The aerodynamic reel includes a body 1, in which a groove 2 is made for threading the thread 3 located along a cylindrical channel for processing the thread and tangentially to it. At an angle to the groove 2 in the housing, channel 5 is made for supplying a gaseous agent, such as air. The outlet of the channel 5 communicates with the groove 2 in its region in front of the entrance to the channel. 4 For convenience of threading, the groove 2 at the inlet 6 is made in cross section tapering along a smooth curve. A lamellar thread guide 7 is pivotally mounted on the body 1, having the ability to overlap the groove 2, Channel 5 may have round, oval or rectangular shapes in cross section (Fig.3.6 and 7). A reel may have several channels for supplying a gaseous agent that are parallel to one another. staggered order (FIG. 5) or one below the other (FIG.). Channel 4 is terminated at the ends (Fig. 8). A reel is installed between the exhaust cylinders 8 of the exhaust device of the machine and its thread guide 9. The winding of the produced 3 is carried out on the cob 10. The air supplied through the nozzle 11 passes through the channel 5, enters the groove 2, in which the air flow expands and passes to the channel k . Due to the tangential positioning of the groove 2 relative to the channel k, the air flow is rotated and consequently twists the thread 3 passing through the channel 4, giving it a false twist. In the process of rotation, the thread between the reel and exhaust cylinders receives an additional intensive twist, as a result, the height of the torsion triangle decreases and, consequently, its strength in this area increases, and this, in turn, leads to a more reliable process flow on the machine by reducing the breakage of the thread. The exit of the air flow from the channel 5 into the groove 2 and the filling of the groove on the drive-in length with the air flow allows you to securely fix the thread in the channel 4 and exclude its exit from the treatment area. When knitting the end of the thread 3 to the reclining sliver after it is cut in order to avoid twisting and breaking the thread with a rotating air flow, the groove 2 is covered with a plate thread guide 7 (dash-dotted position in FIG. 2) and the thread skirts this thread during curling 2. After the completion of the tamping, the spreader manually moves the thread guide 7 to the inoperative position of the thread 3 under the influence of the tension in groove 2 falls into the channel C. This reel will improve the quality of the yarn produced on the machine and reduce it of continuity due to the stability of the false twisting yarn, achieved a reliable locking it in the processing channel, and furthermore, simplify about sluzhivayie when piecing n ti. Stable false torsion of the thread reduces its breakage. Claim 1.
