Abstract:
A spinneret holder assembly for producing a continuous plastic multiple-component yarn with a preset component ratio, comprising, in a mutually superimposed arrangement: a plate for conveying a first component and at least one second component; a distribution plate with first channels for the passage of said first component and a first compensation element for said second component; a pre-spinneret with second channels for the passage of said first component which are aligned with said first channels and a second compensation element for said second component; and a spinneret with extrusion hole which are connected to said channels for the passage of said first component and extend from a region for the distribution of said second component; the paths followed by said first component and said at least one second component being different from one another with respect to their configuration, and the load loss of the various paths that are covered being identical for each component, for a constant ratio between the components of each filament that leaves said spinneret, and wherein said conveyance plate forms a distribution element for the passage of said first component which is fed by a first pump, a first duct for the passage of said second component fed by a second pump being further provided, said first compensation element provided in said distribution plate comprises a V-shaped manifold at the apex of which said duct for the passage of the second component is connected, multiple branches having a variable cross-section, so as to ensure constancy of the amount of second component fed into each one of the distribution branches, extending from said manifold.
