METHOD FOR PRODUCTION OF MINERAL WOOL PRODUCTS WITH COMBINED STRUCTURE Russian patent published in 2009 - IPC B28B1/52 E04B1/74 

FIELD: technological processes.

SUBSTANCE: invention is related to production of mineral wool products, mostly strips and plates with combined structure. Method includes preparation of mineral wool carpet with horizontal position of fiber with binder, carpet displacement, its corrugation, arranging of corrugations, longitudinal cutting of carpet along width in parts, installation of carpet parts on above another, hardening. Carpet corrugation is realised by means of single-sided crumpling. Longitudinal cutting of carpet is carried out into two parts. Prior to installation one above another both parts of carpet are turned around their longitudinal axes for angle of 180 degrees, with change of the first carpet part displacement direction by angle 180>α>0 degrees, and the second carpet part - by angle of 360>γ>180 degrees. The second part of carpet is additionally turned around its longitudinal axis at the angle of 180 degrees, with change of direction of its displacement by angle (γ+α) in reverse direction and is laid under the first part of carpet. Corrugation of mineral wool carper is carried out at sharp angle β in direction of its displacement.

EFFECT: simplified technology and increased quality of mineral wool strips and plates with combined structure.
