ABSTRACT:
An improvement is disclosed for reducing or even preventing interferences or interactions between adjacent, closely-spaced laydown jets utilized in a fibrous sheet laydown process. The improvement comprises positioning an inverted "V-shaped" baffle between adjacent, closely-spaced laydown jets so that the turbulent gas streams produced by each laydown jet are diverted and vented away from the area of sheet laydown on a moving collection belt. The baffle vents the fountain of gas produced by the collision of adjacent laydown jets in a cross-direction to that of the direction of belt movement.
