Abstract
A die head assembly for producing bicomponent meltblown fibers includes a die tip detachably mountable to a support member. The support member conveys first and second polymers separately to the die tip. The die tip has a row of channels defined therethrough that terminate at exit orifices or nozzles along the bottom edge of the die tip. These channels receive and combine the separate first and second polymers conveyed from the support member. An elongated recess is defined in the top surface of the die tip. The recess defines an upper chamber for each of the die tip channels. Stacked breaker plates are removably supported in the recess. The breaker plates have vertically aligned pairs of adjacent holes defined therethrough such that a pair of the aligned holes is disposed in each upper chamber of each channel. A filter screen is in the recess to separately filter the polymers.
