1. Apparatus for the preparation of liquid compounds intended to be sprayed on fleeces or felts made of mineral fiber, with these compounds requiring the combination and mixing of several constituents which are in the liquid state, comprising a preparation container (12) to which the constituents are sent through a given number of conduits (13), the total number of conduits being from 1 to the greatest integer value smaller than the number of constituents, with each conduit (13) being connected by at least one valve (10) to constituent feed equipment, with each valve (10) controlling the sequential introduction of a constituent into said conduit (13), with a mass flow meter-type device being placed on each said conduit (13) downstream from the valves (10), and to a distribution means, to which the compound passes from said preparation container.
