Abstract

La machine comprend un chariot (13) mobile au des­ sus du plan de travail (11B) et portant un rouleau ou cylin­ dre de pression (15) avec des moyens (25) pour la poussée de celui-ci vers le plan de travail et le matériau (M), et com­ prend en outre des moyens de butée (27, 29) pour arrêter le rouleau ou cylindre de pression (15) à une distance du plan de travail (11B) inférieure à l'épaisseur à laquelle le ma­ tériau (M) doit être réduit, ainsi que des moyens de motori­ sation (23) pour imposer au dit rouleau ou cylindre (15) des rotations dans des sens opposés en fonction de la direction de deplacement du chariot (13). The machine comprises a carriage (13) movable at des above the worktop (11B) and carrying a roller or cylin pressure dre (15) with means (25) for the thrust of this one towards the work plan and the material (M), and com further takes abutment means (27, 29) to stop the pressure roller or cylinder (15) at a distance from the plane of work (11B) less than the thickness at which the ma material (M) must be reduced, as well as means of motori station (23) to impose on said roller or cylinder (15) rotations in opposite directions depending on the direction for moving the carriage (13).
