FIELD: technological processes. ^ SUBSTANCE: invention is related to production of mineral wool items, mostly multi-layer ones. Method includes production of mineral wool carpet, its displacement, longitudinal cut of carpet into strips along width, changing shape and size of strips cross section, laying of strips on top of each other, their mutual displacement, hardening. Prior to strips laying on top of each other every strip is turned around its longitudinal axis by angle of 180 degrees, with variation of displacement direction by angle of 180>>0 degrees. ^ EFFECT: simplified technology of multi-layer mineral wool products making. ^ 1 dwg |
