DEVICE FOR WRINGING-OUT OF THREADS AFTER TREATMENT WITH IMPREGNATING COMPOUND Russian patent published in 1997 - IPC

FIELD: production of fabric in textile industry and in manufacture of fan belts in industrial rubber production. SUBSTANCE: device includes installed on frame fixed parts of die in the form of parallel rollers and movable part located between fixed parts. Movable part is made in the form of hook with toroidal surface of bend. Inner radius of hook and radial clearance between working toroidal surface of hook and working cylindrical surface of rollers do not exceed the length of rolled surface and is not less than radius of circumference in which closed contours are inscribed. Closed contours are obtained from cross-section of all threads to be wrung. The device for regulation of the force of wringing is made in the form of air cylinder connected with movable part of the die. Device for changing and control of the magnitude of wringing force is made in the form of air pressure regulator and pressure gauge. Cock for changing-over the direction of air supply and valve supplying air are connected with pneumatic system. EFFECT: extended process capability of equipment due to provision of qualitative impregnation of threads with reduced consumption of impregnating compound. 4 cl, 5 dwg
