Disclosed is a method for manufacturing a mineral fiber-containing element comprising the steps of: providing mineral fibers in the form of a collected web, providing a binder in an amount of 1 to 10 wt % of the total weight of starting materials, subjecting the collected web of fibers to a disentanglement process, suspending the fibers in a primary air flow, and mixing the binder with the mineral fibers before, during or after the disentanglement process to form a mixture of mineral fibers and binder, collecting the mixture of mineral fibers and binder and pressing and curing the mixture to provide a consolidated composite. Disclosed a mineral fiber-containing element produced by that method. Disclosed is an apparatus for the production of a mineral fiber-containing element comprising: a mineral fiber-forming apparatus for producing a supply of fibers entrained in air, binder supply means for supplying binder to the fibers, a first collector arranged to receive the fibers from the fiber-forming apparatus, suction means for applying suction through the collector and thereby collecting the fibers on the collector as a web, a disentanglement apparatus for disentangling the web to provide disentangled fibers, web supply means for supplying the web to the disentanglement apparatus, air supply means for supplying a primary air flow in which to suspend disentangled mineral fibers and, a second collector for collecting the disentangled mineral fibers and binder, and a press for pressing the collected disentangled mineral fibers and binder. |
