A METHOD OF PRODUCING AN ANNULAR INSULATING MINERAL FIBER COVERING, A PLANT FOR PRODUCING AN ANNULAR INSULATING MINERAL FIBER COVERING, AND AN ANNULAR INSULATING MINERAL FIBER COVERING

摘要

In the process, a first non-woven mineral wool material is produced to parallelize a hero direction and a transverse direction; the first nonwoven mineral wool material is annealed in said heat direction; the first non-woven mineral wool material is rotated in the first direction by the slope of the first non-woven mineral wool material, and a climbing mineral wool material is produced, which comprises two coolers of the cold wings of opposite chimneys facing each other in a stack and parallel to the helix and cross strut; separating two bristles from each other along the aforesaid plane and separating them from the non-woven mineral wool material, producing two shrink arches (190 ', 192'); and from the two bristles of the curved half-shell shells, the half-pipe shelf time (190 ', 192') is made into a damp-proof mineral wool as tube shells. The invention also relates to an insulating mineral wool tube shelf time unit and an insulating mineral wool tube shell time. ŕ
