Abstract
The present invention relates to a process for the insertion and conveying of a labile additive, or a mixture thereof, in a transporting pipe, in which a main stream of molten material flows, said process characterized in that it incorporates said additive, or said mixture, in a portion of the pipe delimited by the main stream, according to one of the following alternative modes: a) in a longitudinal direction with respect to the flow direction of the main stream of molten material, or b) in a transversal direction with respect to the flow direction of the main stream of. molten material, or c) according to a composition of the longitudinal (a) and transversal (b) mode, thus forming a resulting stream which keeps the labile additives segregated from the main stream of molten material.
