La plaque porte-pince supérieure (3) est montée mobile par rapport à la plaque porte-pince inférieure (2) pour former un point de serrage (KS) et est sollicitée par un appareil de sollicitation pour produire une force de serrage. La plaque porte-pince inférieure (2) est attachée de manière fixe dans le bâti de machine -lorsque l'on regarde en direction d'un cylindre de détachement (8) placé en aval et monté rotatif- et comprend un moyen d'alimentation (5) destiné à amener le matériau fibreux (F) au point de serrage (KS) de l'unité pince à laquelle est associé un cylindre de peignage (16) monté rotatif au-dessous d'un bâti de machine (MS) et pourvu sur sa circonférence d'au moins un segment de peignage (19) et d'un segment de détachement (20). Le cylindre de détachement (8) susceptible d'être sollicité par des moyens de sollicitation (B1, B2) peut être rapproché du segment de détachement pour former une ligne de serrage (KL). L'invention propose d'effectuer un réglage sur différents matériaux. A cet effet, le cylindre de détachement (8) est monté dans un logement (10) monté mobile dans la direction radiale du cylindre de peignage (16) et sollicité par des moyens de sollicitation (B1, B2), le logement étant relié à un dispositif de commande (17) par l'intermédiaire duquel l'écart (E, E1) entre le cylindre de détachement (8) et la plaque porte-pince inférieure (2) peut être réglé.
