Abstract
Method and apparatus for supplying binder to newly formed mineral wool fibres by means of several distribution means like nozzles or spreaders (30-33, 36-36, 41-43) while said mineral wool fibres are suspended in an air or gas stream on their way to a collection means (29), which in one or more steps form a final mineral wool path (F-J), whereby the binder or binder mixtures from the different distribution means (30-33, 35-36, 41-43) are supplied to different parts of the fibre suspension and in such amounts--in relation to the fibre flow in that part of the fibre suspension, which is actuated by the respective distribution means--that different layers (e.g. F+J, G+I, H) of the final mineral wool path get different content of binder.
