摘要

TITLE: EQUIPMENT FOR THE DOSING AND SPREADING OF FIBERS BETWEEN TWO LAYERS OF BITUMEN EMULSION Equipment for dosing and spreading a layer of mineral, vegetable or synthetic fibers, between two layers of bitumen emulsion It is essentially characterized in that it comprises, in cooperation, at least the following modules: a) a dispenser 11 supplied with sticks or granules which consist of pre-cut fibers assembled together by means of a specific binder and provided, at the outlet, a trough transfer screw 13 capable of dosing the quantity of sticks or granules; b) a centrifugal fan 21, with rigid blades, capable of sucking the sticks or granules coming from the doser 11 and ensuring, by means of said blades , the bursting of said rods or granules and the transfer of the fibers thus obtained to a dispersion chamber 31 capable of balancing their distribution and of spreading them uniformly over the first layer of bitumen emulsion.
