UNIT FOR PRODUCING MINERAL WOOL, AND DEVICE FOR SPRAYING OILING COMPOSITION, PROVIDED IN SUCH A UNIT Russian patent published in 2022 - IPC B05B7/08 

FIELD: spraying devices.

SUBSTANCE: invention relates to an annular spraying device. The annular spraying device for spraying an adhesive composition to mineral fibers contains a contour of distribution of the specified adhesive composition and a set of spraying nozzles communicating via fluid with the distribution contour, placed along a perimeter of the annular spraying device, to spray the adhesive composition to fibers intended to pass inside the annular spraying device defined by the axis of rotation. In this case, each spraying nozzle is oriented inward the annular spraying device with an inclination angle set relatively to the plane of rotation of the annular spraying device. At the same time, spraying nozzles placed sequentially along the perimeter of the annular spraying device are located so that to have an orientation relatively to the plane of rotation of the annular spraying device with different inclination angles.

EFFECT: achievement of homogeneity of distribution of an adhesive composition on glass fiber torus.
