ABSTRACT:
In a method of making non-woven fibrous material such as paper, the papermaking stock as it is being delivered to the foraminous support of a papermaking machine has air under pressure introduced into it to produce foaming of the stock and the stock is subjected to turbulence. This is effected by providing the head-box of the papermaking machine with a slice the body of which includes a slot through which the stock flows to the foraminous support and which is shaped to impart turbulence to the stock. The body also includes an air supply passage which communicates with the slot to introduce the pressurised air into the stock.
