    A roving moving to a spinning machine passes between top and bottom input rolls of which the top roll is adapted, upon breakage of the roving, to be raised by a lift member which is movable into engagement with the spindle of the top roll and carries with it a clamping element which serves to clamp the incoming broken end of the roving against the top roll to retain it ready for subsequent rethreading into the nip of subsequent drafting rollers.

    6.Pr. Dilna machine according to claim 5, on t-; This is due to the fact that the elastic coating of the upper roller has a conical bevel on the end portion of the length. The length of the coating is 0.125-0.25.
    The invention relates to the textile industry and relates to spinning machines for yarn production. The known spinning machine, each workplace of which contains at least one exhaust device and a lever for withdrawing the upper roller of its feed pair from the lower driving cylinder at. a yarn break set-up: with its curvilinear surface interacting with the trunnion of the upper aalik and raising it, and containing a means for clamping a roast when the yarn is broken, having a console mounted on the palei lever, ij. . The disadvantage of this machine is that it is difficult to maintain due to the fact that after a break in the yarn there is no automatic filling of the roast into the feeding pair of the exhaust device. The use of supplement "-. constructive means for refueling roving complicates and increases the cost of machine design. The purpose of the invention is to simplify servicing by providing an automatic filling of the roving into the steam supplying appliance. This goal is achieved by the fact that in a priloil machine, each workplace of which contains at least one exhaust device and a lever for retracting the upper roller of its feed pair From the lower drive cylinder when the yarn is broken, installed with the possibility of its curvilinear surface interacting with pinning the upper roller and lifting it, and containing a means for clamping the rim when the yarn is broken, having a finger cantilevered on the lever, the lever is mounted with the possibility of bringing its curvilinear surface to At the same time, the axis of rotation of the lever is located under the driving cylinder of the feed pair, and a finger for clamping pins (111 fingers fixed on the lever in the area of its curvilinear surface with the possibility of contact with the outer cylindrical surface of the upper roller. The finger is set in such a way that the zone his contact with the upper roller is located below his pin. The lever is set relative to the feeding pair from the side of the roving into it. The lever is set relative to the supply pair on the exit side of the roving. The pair has two coaxially arranged upper rollers, each roller being mounted for movement relative to the other in a direction perpendicular to its axis of rotation. The elastic coating of the upper roller has tapered bevels on the end sections with a length of 0.125-0.25 of the coating length. FIG. 1 shows an exhaust device of a machine in the working position, a transverse section; in fig. 2 - the same, in the position when the yarn is broken; in fig. B-b - options for installing a lever with a finger for clamping a roving relative to the twin upper rollers of the feed pair; 7 is an embodiment of the exhaust device; in fig. 8 - installation of double outer rollers of a pitakad.i pair; Figures 9 and 10 are embodiments of the mechanism for turning a lever; in fig. 11 - the end part of the upper roller of the pitqvdei i pair. Each workplace of the spinning machine has at least one exhaust device, the contents of which supply the pair with the lower driving cylinder 1 and the upper roller pressed against it 2. Between the supply and middle pairs of the exhaust device is installed / single-arm lever 3, OSB, 4 of which located under the cylinder 1 (Fig. 1). The lever 3 has a curved surface 5 to retract the upper roller 2 from the cylinder 1 when the yarn is broken and. means dd clamping rove b, having a finger 7, mounted console on the lever 3 in the area of its curvilinear surface 5, which is located eccentrically relative to axis 4, Element 8 is fixed on the lever to rotate it. During the operation of the machine, the roving b, from the guide funnel 9, enters the clamp of the absorbing pair of the exhaust device, moves B: the stretching process to the preconditioning table 10 and the exit from the exhaust device in the form of NEd4KH is twisted in the yarn. a yarn break element 8 rotates the lever 3 counterclockwise on axis 4, as a result of which its curvilinear surface 5 inwards jtuiT in contact with pin 11 of the upper rail 2 and retracts its cylinder i. At the same time, finger 7 presses the level to the outer cylindrical surface: 12 roller 2 in his area Loose below pin 11 (Fig. 2). When the lever is rotated clockwise, its curved surface moves out of contact with the pin of roller 2:. As a result, it is lowered onto the cylinder, and the roving is released from the clamp with a finger and fed by the feed pair through the table 10 to the middle and high pairs. In the case of drawing a rove with a small fiber length, the guide table 10 may be absent (Fig.7. The feeding pair may have two coaxially arranged upper rolls, each of which is mounted for movement relative to, the other in the direction perpendicular to its axis rotation (Fig. 3-6,8). The levers are positioned with one side of the upper rollers and one on the other side of the upper rollers (Fig. 3) inserted into the pitakadi (Fig. 3). The right upper roller is retracted from the cylinder, and the left roller is pressed into it's time to cylinder. The option is possible: placing the levers relative to the feeds of the pair on the exit side of the rovings from it (Fig. 4). According to Fig. 5 and b, the levers are installed on the outer ends of the upper rollers on the input side of the pair of rovings and on the side The upper rollers of the flying pair are installed in such a way that when you lift one of them, for example the left one (Fig. 8), the right roller remains pressed to the drive cylinder. It is possible to provide an elastic coating for each upper roller 2 with a conical bevel 13 on the end portion of a length of 0.1250, 25 of the coating length (Fig. 11). The bevel provides adherence of the roller coating in this zone to the drive cylinder 1 without deforming the coating in the zone of its cylindrical surface and allows the adjacent roller to be lifted without disturbing the contact of the other roller with the cylinder. The lever can be rotated manually by element 8 or from an actuator connected to a yarn break sensor. The mechanism 14 includes a locking dog 15, interacting with the protrusion 16 of the lever 3, made two shoulders and spring-loaded spring 17 (Fig. 9). In the event of a yarn breakage by the sensor signal, the mechanism 14 brings the pawl 15 out of contact with the protrusion 16 and the rod 1-7 rotates the lever 3, bringing the curvilinear surface 5 into contact with the upper roller trunnion 11 entering the recess 18 on this surface. In the embodiment (Fig. 10), the second arm 19 of the lever 3 is connected with the actuator 20 by the anchor 21. When the sensor signal about the breakage of the yarn to the actuator input 22 is received, the anchor is shifted to the right by turning the lever 3 to lift the upper roller 2. Received to the input 23 of the signal mechanism 20, the anchor is moved to the left. transfer lever in the off position. The coistructure of the spinning machine allows a reliable fixation of the roving when the yarn is cut, followed by its automatic insertion into the exhaust device, which prevents the maintenance of the machine.
