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 the first component and a first compensation element for the second component; a pre-spinneret with second channels for the passage of the first component which are aligned with the first channels and a second compensation element for the second component; and a spinneret with extrusion holes which are connected to the channels for the passage of the first component and extend from a region for the distribution of the second component. The paths followed by the first component and the second component are different one another and the load loss of the various paths that are covered is identical for each component, so as to obtain a constant ratio between the components of each filament that leaves the spinneret.
