Abstract
Method for producing a fibrous product comprising: passing a texturized yarn (10) through a first passage (12) having a first outlet (14); projecting the texturized yarn (10) from the first outlet (14), inside a chamber (20), so as to fill the chamber (20) with the texturized yarn (10), thereby forming a first segment (31) of the fibrous product; moving the first segment (31) away from the first outlet (14); and forming a second segment (32) of the fibrous product in place of the first segment (31) and contiguously to the first segment (31), as many segments as necessary being contiguously formed by repeating the above steps. Apparatus for implementing the method.
