Abstract
Le sac filtrant est formé d'un panneau comprenant deux parties de largeurs différentes, ces largeurs étant telles que lorsque le panneau est plié suivant une ligne de pliage (4) les deux parties forment un panneau à deux plis présentant un coté dépassant (9). Le coté (9) est replié suivant une deuxième ligne de pliage sur le coté libre du pli (2). Les cotés précités et le pli le plus large sont fixés ensemble par une couture de surjet (13) de façon qu'il soit formé un tube (12). L'invention concerne aussi un procédé de fabrication du sac filtrant.
