  • Such pliers are known.

  • the object of the invention is generally to design the pliers unit specified at the outset in such a way that clamped fiber whiskers can be combed out as completely as possible through the circular comb. For this purpose, it should be possible to adapt to different cotton weights in a simple manner and without risk of damage to the round comb.

Abstract

L'unité à pince possède une plaque de pince supérieure (10) et une plaque de pince inférieure (9). La plaque de pince supérieure (10) peut être pressée avec son bord inférieur contre la face supérieure (9.2) de la plaque de pince inférieure (9), afin de serrer de la ouate à peigner qui est amenée, de manière à ce qu'une barbe de fibres dépassant de l'unité à pince puisse être enlevée par peignage par un peigne circulaire de la peigneuse. A cet effet, une saillie (16) orientée vers le bas s'étend sur le bord inférieur de la plaque de pince supérieure (10) devant le bord avant de la plaque de pince inférieure (9), afin d'orienter la barbe de fibres contre les aiguilles (18) du peigne circulaire. Cette saillie (16) consiste en un rail de plastique fixé, de façon à être interchangeable, à un corps de base (15) de la plaque de pince supérieure (10). Il existe plusieurs rails de plastique (16) de différentes hauteurs correspondant aux différentes épaisseurs de la ouate à travailler. De cette façon, une adaptation à différentes épaisseurs de ouate est possible de manière simple. Même si par erreur la hauteur du rail de plastique (16) est choisie trop grande, ce dernier ne peut pas endommager le peigne circulaire de la peigneuse, étant donné qu'il est en plastique.
