Abstract: An assembly and method of reducing discoloration of a foam material resulting from laser processing the material comprising an assembly configured for positioning below the material being processed and for directing air into open cells of the open-cell foam material to pressurize the material during laser processing. The assembly comprises an air delivery mechanism comprising one or more apertures for an air chamber positioned directly below the material travel path. Aligning the one or more apertures with the axis of the laser beam and its focal point when the material is positioned above the one or more apertures and pressurizing or filling of the open cells with air in the direct vicinity of the target area reduces processing related discoloration of the material. The cells are laser processed concurrently with pressurization thereby substantially reducing settling of debris and smoke on the material and reducing discoloration.

Abstract: An assembly and method of producing one or a plurality of reservoirs or wells having a bulge when viewed in cross-section, in a foam material, with a laser processing system. The assembly comprises a housing configured to receive a galvo therein, and wherein the first housing has exterior surface topography comprising a plurality of apertures; a compression mechanism comprising an exterior surface topography having a plurality of surface protrusions thereon for compressing the material passing over at least one of the plurality of surface protrusions; and wherein the housing and the compression mechanism are spaced apart providing a gap there between for receiving a web of the material therein. Laser processing comprises compressing the material around a target area on a first surface of the material and concurrently directing a focal point of a laser beam to the target area to produce the reservoirs.
