Method of manufacturing glass fiber core thermal insulation panels involves drawing mineral fibers as primary web, sub-dividing into secondary web, rotating, recombining and surrendering into a sideways pendulum feed on moving conveyor belt

摘要

In a process to make panels, mineral fibers are drawn from a chamber as a primary web (2) which is then sub-divided into identical secondary webs (5) by parallel knife blades (4). The secondary webs (5) are then rotated through 90 deg , recombined and surrendered into a sideways-pendulum feed (8) on a moving conveyer belt (9). The fibrous panels are manufactured from a continual web which is subsequently cut into lengths. The fibers are orientated essentially at 90 deg to the panel surface. The secondary-webs are arranged as a sandwich before twisting about their longitudinal axis. The secondary fibers are compressed in two horizontally-opposed directions during or after pendulum folding on the conveyer. The secondary fleece (11) is then fed through a hardening oven.
