Abstract
The invention relates to a blowing device (4) for a laser system (1) used for separating or welding workpieces (17). The blowing device (4) has at least one nozzle assembly (5), which generates a gas stream (7) that is oriented at an angle to the laser beam (3). The blowing device also has an air supply (8) which, on one side of the nozzle, leads into the proximity of the nozzle opening (6) and which is provided for an air supply stream (10) that is fed to the gas stream (7) in an essentially parallel manner or at an apex angle. A second air supply (9) is arranged on the other side of the nozzle. Said second air supply leads into the proximity of the nozzle opening (6) and is provided for a second air supply stream (11) that is fed to the gas steam (7) in an essentially parallel manner or at an apex angle. A protecting glass (13), which is oriented toward the gas stream (7) in an essentially parallel manner, can be alternatively or additionally placed in the proximity of the nozzle opening (6). Said protecting glass is provided in the form of a pane and directly abuts against the nozzle opening (6) in a sealed manner. In the preferred embodiment, the outer cross-section of the nozz…
