Abstract

La présente invention a trait à un groupe de cage (1) pour un banc d'étirage d'une machine textile avec une cage (3) pour le guidage de deux manchons de guidage (4a, 4b) enlaçant un double cylindre presseur (2), avec un support de cage (13) disposé de manière détachable en un point de fixation central (23) de la cage (3) et comprenant deux faces latérales orientées à l'opposé l'une de l'autre (35a, 35b), et avec un élément de guidage (14) dont chaque extrémité (14a, 14b) fait saillie des deux faces latérales (35a, 35b) du support de cage (13). La cage (3) comprend respectivement un bord de renversement (8a, 8b) pour renverser les manchons de guidage (4a, 4b). Afin d'empêcher une rotation de l'élément de guidage (14) autour du point de fixation central (23) de la cage (3), le groupe de cage (1) comprend entre chaque bord de renversement (8a, 8b) et l'élément de guidage (14) à une certaine distance (24) du point de fixation central (23) de la cage (3) au moins un élément de support (25) pour supporter l'extrémité (14a, 14b) respective de l'élément de guidage (14).
