Waterjet cutting machine comprising a device for moving a plate in a plane

A movement device for moving a plate parallel to itself in a plane P, said plate comprising:

• at least two opposite edges parallel to each other, wherein said device further comprises at least two arms parallel to each other and able to move in a plane parallel to said plane P, one of said two arms being called the master and directly moved by a first actuator, the other then called the slave being moved by the master arm by means of a connection member connecting together said master and slave arms, said connection member being articulated at each of its ends on the master and slave arms about axes perpendicular to said plane P,
• a drive member mounted pivotally at one of the ends of each of said arms, about an axis perpendicular to said plane P and moved by a second actuator, the drive member associated with the master arm cooperating with an actuation member disposed along the edge of the plate and the drive member associated with the slave arm cooperating with an actuation member disposed along the other edge of the plate.

A waterjet cutting machine comprising:

• at least one frame, a cutting head provided with at least one immobile nozzle secured to said frame, and a cutting table disposed under the nozzle, wherein a device for moving a plate in a plane P parallel to itself is secured to said frame, and in that at the cutting table defines said plane P of movement of the plate.
