The present invention relates to a method and a device for generating a two-phase gas-particle jet for treating surfaces by means of particles, in particular CO2 dry ice particles, using a two-phase gas-particle jet. Included is a transformlighting module for transforming and lighting vertex data. The capture frame contains a second gasket that seals against a removable cover and further contains provisions for latching the removable cover to the enclosure. The shear forces disrupt the web increasing the softness and decreasing the stiffness of the web.
