    摘要: A worksheet supporting bed for a laser cutter comprises a series of thin bands arranged parallel to one another in a common plane to form an even support surface. The bands take the form of endless strips each of which being tensioned between two braces. One of the braces is fixedly secured to an end frame portion of the bed and the other brace is secured via a tensioning screw to an opposite end frame portion. By turning the screw, the tension in the associated endless band is adjusted, and by removal of the screw, the associated endless band may be removed and another one substituted for it. The bands define elongated slots which may be penetrated by an optional mechanism which engages a worksheet supported on the bed and transports it to or from the bed. The upper edges of the bands may be smooth so that fabric sheets may slide along it easily without snagging. Also, the bed is gas-permeable.

    摘要: A method of cutting a multilayer pile of sheet material with a beam of laser radiation is disclosed. A laser beam having a low order mode intensity distribution is focused onto the pile and during cutting a stream of liquid coolant is directed into the material vaporization region to absorb energy from the outer region of the mode distribution which could otherwise result in adhesion of adjacent layers, globularization, singeing or other undesired effect.
