  • Patent number: 7611660
    Abstract: The present invention relates to an apparatus and method for cooling material during continuous vacuum forming. The apparatus includes one or more cooling regions positioned adjacent one or more vacuum regions. A rotatable support belt including perforations therein supports a flexible patterned belt. The flexible patterned belt includes apertures spaced along the length and width thereof. The one or more cooling regions provide a cooling fluid to be drawn through the apertures in the flexible patterned belt to form an area of cooling fluid on the flexible patterned belt which contacts a bottom surface of a hot material received on the flexible patterned belt in order to cool the bottom surface of the material and the flexible patterned belt. The vacuum regions are in fluid flow communication with the perforations of the support belt and the apertures of the flexible patterned belt for drawing the material onto the flexible patterned belt.
