Abstract
Apparatus for the production of a nonwoven material wherein a web of material is drawn over a series of parallelly aligned porous rolls. The web is treated with a jet of pressurized water as it moves in contact over each roll. The web is compressed between the first roll in the series and is wetted by a curtain of water as it is being compressed to increase the density of the web material prior to its being treated with the pressurized jets of water.
