DEVICE FOR APPLICATION OF POWDER ONTO MATERIAL CLOTH Russian patent published in 2008 - IPC B05C19/04 

FIELD: technological processes.

SUBSTANCE: invention is related to the filed of plants for application of loose materials (powders) on the surface of different materials cloth, such as paper, non-woven materials, leather and its substitutes, fabrics, and may be used in manufacture of wallpapers. Plant for powder application onto material cloth contains feeding bunker, cylindrical dosing shaft, which is installed in rotation supports under feeding bunker and contacts with them, and cleaning brush that is fixed in rotation supports. Feeding bunker is equipped with sealing device that is provided at the outlet of dosing shaft from area of contact with feeding bunker. Feeding bunker is installed with displacement along horizontal in respect to vertical axis of transverse cross section of dosing shaft. Sealing device is made in the form of elastic plate, which is installed along tangent to the dosing shaft transverse cross section circuit contour part inside the bunker and is equipped with mechanism for elastic plate pressing to the surface of dosing shaft. Specified shaft has smooth surface with deepenings that are evenly installed on this surface. Cleaning brush is installed in respect to dosing shaft from the side of its outlet from area of contact with feeding bunker and is installed so that between surfaces of cleaning brush and dosing shaft air gap is provided from 0.1 to 1 mm. Angular rate of cleaning brush rotation is more than angular rate of dosing shaft rotation 5...10 times.

EFFECT: increase of efficiency, reliability of plant for application of loose materials and reduction of expenses in its operation.
