ABSTRACT:
A meltblowing die designed to efficiently receive a preassembled die tip assembly is described. The die assembly includes a die body mounted on a meltblowing machine and a replaceable die tip assembly. The die tip assembly includes a mounting block, to which are mounted a die tip and air knives on opposite sides of the die tip. The positions of the air knives are adjustable to set air gap and set back parameters important in proper operation. The die tip assembly is moved into and out of the die body after air knife adjustment, permitting the adjustment to be made with the die tip assembly off the machine, and allowing rapid replacement. The replacement die tip assembly is preheated, permitting replacement while the die body is still hot.
