DEVICE AND PRODUCTION METHOD OF WORKPIECES FOR ROTOR BLADES OF WIND-DRIVEN POWER PLANTS, AND ALSO ROTOR BLADE AND WIND-DRIVEN POWER PLANT WITH SUCH ROTOR BLADE Russian patent published in 2017 - IPC B29C53/56 B29C53/82 B29C70/36 B65H49/00 B65H69/06 B29L31/08 F03D1/06 

FIELD: power industry.

SUBSTANCE: group of inventions relates to a device (1) and a production method of end parts workpieces (101) for the wind-driven power plants (versions) rotor blades and the wind-driven power plant. The device contains the winding mandrel (3a), which is made with ability to rotate for winding of preferably band-shaped fiber composite material. The device (1) contains also mounted with ability to move along the winding mandrel the impregnating device (5) for the fiber composite material impregnation before being wound into the winding mandrel, and the loading mechanism (7) with the storage device to supply the fiber composite material, mounted with ability to move along the winding mandrel, preferably simultaneously with the impregnating device. The method contains the feeding operation of the fiber composite material by means of the loading mechanism. The material is fed through the impregnating device to the winding mandrel and the winding of the fiber composite material into the winding mandrel is performed by rotating it.

EFFECT: manufacture of the end parts for the rotor blades with the minor variations in resistance.
