Abstract

L'invention concerne une machine à couper les carreaux qui comprend un socle (1) s'étendant horizontalement dans la position d'utilisation de la machine, destiné à recevoir un carreau (8), ainsi qu'un chariot (3) qui peut être déplacé horizontalement au-dessus du socle (1) le long d'une glissière (2) et sur lequel est articulé un support d'organe de coupe (4), en particulier un support de molette de coupe qui porte un organe de coupe (5), en particulier une molette de coupe. Lorsque le chariot (3) est déplacé le long de la glissière (2) dans une direction de coupe (S), le support d'organe de coupe (4) s'appuie contre une butée (6) par l'intermédiaire d'une contre-butée (7) de sorte que l'organe de coupe (5) soit soumis à une force vers le bas verticalement pour faire une entaille dans le carreau (8). L'invention vise à perfectionner avantageusement cette machine en ce qui concerne son utilisation. À cet effet, le support d'organe de coupe (4) est articulé sur le chariot (3) de façon à glisser ou rouler sur le carreau (8) sensiblement sans application de force verticalement en cas de déplacement du chariot (3) dans une direction opposée à la direction de coupe (S).
