Abstract
Equipment for the laser cutting of metal sheets is to hold the metal sheets in a vertical plans by means of a laser-focusing head (10) which is movable in a vertical plans relative to the metal sheet (12). The equipment includes an abutment member (18) carried by the focusing head (10) and intended to bear against that face (20) of the sheet (12) facing the focusing head (10).
Claims12
Equipment for the laser cutting of metal sheets, comprising:
- means for supporting a metal sheet to be cut in a plane,
- a laser focusing head movable relative to the metal sheet in a plane;
- and
- an abutment member carried by the focusing head and intended to bear against that face of the sheet facing the focusing head;
- wherein the abutment member comprises two shaped discs spaced from each other and having respective mutually facing surfaces which define a channel for the evacuation of a return gas flow.
