In Fig. 1 shows schematically a section of the device for impregnation of fiber.

In Fig. 2 shows an embodiment of a matrix, located on the bracket, is provided with an elastic compensator governing minimum clearance Spinneret.

Device for impregnation of the fibers on the winding machine with filling bobbins includes a camera 1 with throttle hole 2 for supplying a sealing composition into the gap of the nozzle 3 formed by the outer surface 4 of the camera 1 in the area of the throttle hole 2 and the outer surface 5 located opposite node, the system of pipes 6, 7 for supplying under pressure impregnating composition from the tank 8 for storing mounted on the base 9 of the machine, into the chamber 1 and the outlet thereof, and means tensioning of the fibers 10. The device is equipped with a sensor 11 adjust the flow of impregnating composition, established in camnago holes 2, made in the bottom 14 of the camera 1, and the horizontal location of a node is made in the form of a matrix 15 with shaped hole 16, forming the tub surface 5 facing the bottom 14, and a means of tensioning the fibers 10 are made in the form of a system of movable rollers 17 having a cross section with a pear-shaped profile, and is located behind Villeroy 3 in the direction of the fibers 10.

In addition, the orifice 2 for supplying a sealing composition into the gap of the die 3 and figure the hole 16 may be offset from the cross section with the minimum clearance of the die 3 by the surfaces 4 and 5 of the bottom 14 and the plates 15 in the direction of filling of the spool 18.

And figured hole 16 on the matrix 15 may be in the form payable with the tail pointing in the direction of movement of the fibers 10.

When this profile throttle openings 2 in the bottom 14 of the camera 1 may be in the form of an expanding cone directed towards the matrix 15.

In one embodiment, the profiles of the bottom 14 of the camera 1 and the matrix 15 in cross section with a minimum gap can be in the form of the sphere.

In addition, the control valve 14 of the rolling rod 13 may be made of Teflon.

Device for impregnation of the fibers on the winding machine with filling bobbins works as follows.

A sealing compound from the tank 8 for storing mounted on the base 9 of the machine, the pipe 6 is fed under pressure into the chamber 1. The amount of impregnating composition supplied into the chamber 1, as in the filling process, and in the process constantly regulated by the sensor 11. The excess impregnating composition discharged from the chamber 1 via line 7. The orifice 2 for supplying a sealing composition into the gap of the die 3 at the time of filling of the chamber 1 is closed by the valve 13. The fiber 10, which is on filling the spool 18, is first passed through the gap of the die 3, and then bypass them a system of movable rollers 17, creating, thus, the tensile stress, the tension in the fiber 10 from the exit from the die 3 to the product subjected to the winding. Due to the drop of the profiles of the rollers 17 is automatically created the necessary tension, oriented in the direction of movement of the fiber 10. For impregnation of the fiber 10 open the orifice 2 by moving the rod 12 with the valve 13 wego composition depends on the magnitude of opening of the throttle hole 2 and is regulated by the movement of the rod 12 with the valve 13. The orifice 2 in the bottom 14 of the chamber 1, having the form of an expanding cone directed towards the matrix 15, and figured the hole 16 in the matrix 15 form an impregnating bath filled with an impregnating composition, the fiber enters the specified bath in unstretched condition, which provides a more complete impregnation of the fiber 10. Due to the fact that curly hole 16 on the matrix 15 has the shape payable with the tail pointing in the direction of movement of the fibers 10, the excess impregnating composition are removed from the fiber 10, and the offset curly holes 16 in the direction of filling of the spool 18 also contributes to a more complete and efficient impregnation of the fiber 10. In the case of education site on the fiber 10, or any other deviations from the standard size of the fiber 10 with the passage of this site through the die plate 3 due to the presence of elastic compensator 20, made for example in the form of a spring, the latter will be compressed and the gap in filiere 3 will increase, passing the node that will prevent breakage of the fibers 10 and will continue to maintain a minimum clearance filiere 3.
