Abstract

L'invention concerne un finisseur à coffrage glissant comprenant un mécanisme de roulement (3) qui porte un bâti (2) déplaçable en hauteur sur lequel est prévu un dispositif de transport (23) pour amener un matériau fluide, le bâti présentant une unité de montage (8) pour fixer un dispositif (10) pour façonner le matériau fluide. Le finisseur à coffrage glissant selon l'invention est caractérisé en ce que l'unité de montage (8) comprend, pour la fixation du dispositif de façonnage du matériau fluide, au moins deux éléments de fixation (16) en forme de griffe qui sont disposés sur l'unité de montage de manière à s'ouvrir dans la même direction. À ces deux éléments de fixation (16A à 16E) en forme de griffe de l'unité de montage (8) du finisseur à coffrage glissant (1) sont associés au moins deux éléments de retenue cylindriques (17A à 17E) qui sont disposés sur l'unité de montage (9) du dispositif de façonnage du matériau fluide (10) de telle manière que leurs axes s'étendent transversalement au sens de travail (A). Les éléments de fixation en forme de grille du finisseur à coffrage glissant qui sont ouverts dans la même direction accueillent les éléments de retenue cylindriques du dispositif de façonnage du matériau fluide. Une variante de réalisation prévoit la disposition d'éléments de retenue cylindriques sur l'unité de montage du finisseur à coffrage glissant et d'éléments de fixation en forme de grille sur l'unité de montage du dispositif de façonnage du matériau fluide. Il est avantageux que les éléments de fixation ou encore les éléments de retenue du finisseur à coffrage glissant puissent absorber tant le poids du dispositif de façonnage qu'une force s'y opposant, sans qu'il soit nécessaire de soumettre à une pression des dispositifs cylindriques hydrauliques ou pneumatiques.
