The object of the present invention is a laser cutting equipment, comprising a table (1) along which a band of sheet- metal (2) unwound from a coil moves continuously, a gate assembly (3) equipped with a laser head (4), and a control system (5), wherein the gate assembly (3) is slidably moved over the table (1) surface in two perpendicular table (1) plane axes, and the table (1) comprises a plurality of supporting rolls (6), deployed perpendicular to the sheet- metal (2) transport direction at preset distances, not larger than the diameter of a single support roll (6), wherein the supporting rolls (6) are bearing mounted in such a way that they can freely rotate around their own axes, and there is a follow-up table (7) equipped with a slot (8) to evacuate material subject to laser machining in the table (1) between the supporting rolls (6), while the movement of the follow-up table (7) along the axis of the sheet-metal (2) movement is coordinated with the gate assembly (3) movement, characterized in that the supporting rolls (6) are seated in the table guide (9) and are slidably moved in it along the axis of the sheet- metal (2) transport direction, wherein the supporting rolls (6) are connected with one another by means of flexible connectors (10). The object of the invention is also a method of laser cutting.
