Process for the production of sandwich elements from reactive plastics material

Image Number 4 for United States Patent #7293594.

The invention relates to a process for the production of sandwich elements (so-called panels), in which the rising reactive mixture is guided, when it rises, through guide elements arranged between the upper and lower outer layers. This process produces void-free panels having a regular cell structure. The invention also relates to an apparatus useful for the production of such sandwich elements.
