Abstract

Selon l’invention, un motif continu de matériau de filetage (3) est formé par la mise en rotation d’une taraudeuse (37) sur la surface circonférentielle d’un élément de support rotatif (10) pourvu de tiges de filetage (11) saillantes. Dans cet exemple, un support de retenue de  taraudeuse (38) pourvu de la taraudeuse (37) est entraîné par deux moyens manivelle d’entraînement (32a, 32b), et des servomoteurs (33Ma, 33Mb) servent de sources d’entraînement respectives pour lesdits moyens (32a, 32b). Ainsi, dans la production d’une feuille (5) destinée à un sac d’extraction résultant du placement d’un matériau de filetage long dans un motif rotatif déterminé, les différentes procédures et le changement du motif rotatif du matériau de filetage (3) sont non seulement facilités mais la vitesse de production est également accrue.
