Abstract
There is disclosed a melt-blowing die head having a die tip which, instead of a number of individual orifices, has a single continuous slot opening running its length. In addition the die tip is reinforced by means of aerodynamically shaped bosses in the fluid delivery channels which bear between the air plate and the exterior surface of the die tip. The die tip may also have reservoirs at either end in which debris may be collected when the slot is cleaned while the die head is in place on a melt-blowing machine.
