In a heading machine (1) including a travelling mechanism (2) and a cutting boom (3) or frame, the cutting boom (3) or frame carries at least two rotating cutting heads (5) whose axes of rotation (6) extend in the heading direction or enclose acute angles with the heading direction and which, together, define a cutting profile having a profile width (a), as well as two cutting rollers (8,10) arranged substantially parallel and behind the cutting heads (5) and capable of being positioned on the floor (9) and on the roof (7), respectively. Both cutting rollers (8,10) comprise end portions (25) which are extendible to the width (a) of the profile for the formation of a substantially rectangular cutting profile.

La présente invention concerne une machine de creusement (1) comportant un mécanisme de roulement (2) et un châssis ou bras orientable de coupe (3). Ledit châssis ou bras orientable de coupe (3) porte au moins deux têtes coupantes rotatives (5) dont les axes de rotation (6) s'étendent dans le sens de creusement ou forment un angle aigu avec le sens de creusement et qui définissent conjointement un profil de coupe avec une largeur de profil (a), ainsi que deux cylindres de coupe (8, 10), disposés de manière sensiblement parallèle et derrière les têtes coupantes (5), qui peuvent être positionnés sur la base (9) ou le faîte (7). Les deux cylindres de coupe (8,10) présentent des sections d'extrémité (25) pouvant se déplacer sur la largeur de profil (a) pour réaliser un profil de coupe sensiblement rectangulaire.
