Abstract:
A melt spinning apparatus for extruding at least first and second liquids into multi-component filaments having a side-by-side cross-sectional configuration of the first and second liquids, comprising:a die tip block including a recess communicating with a set of first liquid discharge outlets and a set of second liquid discharge outlets arranged in respective pairs of said first and second liquid discharge outlets communicating with each other; an insert received in said recess and separating said recess into first and second liquid passages, said first liquid passage communicating with said set of first liquid discharge outlets and said second liquid passage communicating with said set of second liquid discharge outlets, said insert including a first liquid input configured to receive the first liquid and to communicate with said first liquid passage and including a second liquid input configured to receive the second liquid and to communicate with said second liquid passage, said first and second liquid passages respectively delivering the first and second liquids to said first and second sets of liquid discharge outlets to form the multi-component filaments; and a spacer received within said recess between said die tip block and said insert, said spacer having a predetermined thickness to selectively offset said insert with respect to said recess and change respective width dimensions of said first and second liquid passages.
