DEVICE USED FOR IMPREGNATION OF THE FIBROUS LENGTHENED MATERIAL WITH THE BINDING Russian patent published in 2008 - IPC B05C1/00 

FIELD: chemical industry; textile industry; other industries; production of the devices used for impregnation of the fibrous lengthened material with the binding.

SUBSTANCE: the invention is pertaining to the devices used for impregnation of the fibrous lengthened material with the binding. The device used for impregnation contains the impregnating block made in the form of the tank with the holes for feeding of the binding on the material, the fitting pipes for feeding of the binding into the impregnation block. On the external surface of the impregnation block in the area of location of the holes there is the recess and the holes of the impregnation block are disposed in the staggered order. Under the recess with the holes of the impregnation block additionally there is the mounted support deck with the capability of adjustment of the gap, through which the fibrous lengthened material is fed in. The support deck is made convex, and the part of the impregnation block with the holes and the recess facing the support deck is made equidistantly to the convex surface of the support deck. The value of the gap is determined by the formula. The device allows impregnation of the material with the highly-viscous bindings, including their mixtures with the powder fillers with the simultaneous adjustment and regulation of the thickness and uniformity of the binding deposition on the material.

EFFECT: the invention ensures impregnation of the fibrous lengthened material with the highly-viscous bindings, their mixtures with the powdery fillers at the simultaneous adjustment and regulation of the thickness and uniformity of deposition of the binding on the material.
