<p>A molten fiber material flow (3) is shaped into many fibers (4) by means of a liquid jet (2) such as water jet in place of a pressurized gas or air. The flow (3) moves down in a vertical direction while the water jet (2) cuts it at an inclined angle (A). The water jet (2) is formed by at least one nozzle (1) of flat or round type. <IMAGE></p>
