Abstract

A method of producing a mineral fiber-insulating web comprises the steps of firstly producing a first non-woven mineral fiber web defining a longitudinal direction parallel with the mineral fiber web transversal direction parallel with the mineral fiber web. Secondly, the web is moved in the longitudinal direction and cut parallel with the longitudinal direction and perpendicular to the transversal direction so as to produce a plurality of parallel strips. Thirdly, the strips are tilted so as to turn the mineral fibers of each of the strips from the arrangement in the transversal direction to an arrangement perpendicular to the longitudinal direction and the transversal direction. The tilted strips are thereupon adjoined so as to produce a second non-woven web containing mineral fibers arranged perpendicular to the longitudinal and transversal directions. A third non-woven mineral fiber web is produced and adjoined to the second mineral fiber web.

METHOD FOR THE PRODUCTION OF IA NILATION TAPE OF MINERAL NLAKMA INSTALLED1 FOR THE PRODUCTION OF IA TAPE OF MINERAL FIBERS AND BOARD ISOLATED IN MINERAL FIBERS

The present invention relates mainly to the technical field for the production of mineral fiber insulation boards. Mineral fibers generally contain mineral wool fibers, glass fibers, etc., more specifically, the present invention relates to a new technique for the production of mineral fiber insulation tape from which mineral fiber insulation panels are cut. Mineral fiber insulation boards made of mineral fiber insulation tape prepared according to the present invention exhibit a number of positive features in terms of mechanical characteristics, such as modulus of elasticity, strength, low weight and good thermal insulation ability.

So far, mineral fiber insulation tapes have so far been generally manufactured as homogeneous tapes, ie. strips in which the mineral fibers which comprise the mineral fiber isotope strip are generally oriented in a single predominant direction, determined in particular by the orientation of the production line, which produces and transports mineral fiber insulation tape during the production process. A product made of a homogeneous mineral fiber insulation tape exhibits certain characteristics due to the integrity of non-mineral fibers and, in particular, of fibers inside the mineral insulation insulation strip made of mineral fiber mineral slabs such as mineral fiber insulation tape are also determined, in particular, by the weight of the surface unit and by the density of the mineral fibers on the mineral fiber insulation board.

Advantageous characteristics of mineral fiber insulation panels of different structure have been achieved to a certain extent, and techniques have been developed for the production of mineral fiber insulation panels in which the mineral fibers are oriented in a general direction other than the direction determined by the production line, see international patent application, International Application .and PCT / JOhal / 00383, International Publication.

ha * ig. 1 is the first step in the production of a mineral fiber insulation strip. This first step involves the formation of mineral fibers from some molding mineral mineral that is obtained in the furnace 30 and extending from the chute 32 of this furnace 30 to a set of four rapidly rotating rotary withdrawing wheels 34 to which the mineral forming melt the fibers are fed in the form of a stream of mineral fiber melt 36. Because the stream of mineral fiber melt 36 is fed to the rotary withdrawal wheels 34 radially thereto, simultaneously to the rapidly rotating rotary threads. tow wheels. 34, a stream of cooling gas flows in an axial direction toward them, causing a formation.
