a shatter -, bullet - and / or soundproof laminate is assembled of two or more parallel glass panes and one or more layers of transparent synthetic plastic material , one layer between each pair of neighboring panes . the laminate is assembled while the lowermost pane is supported from below in a horizontal or nearly horizontal plane , and the plastic material is admitted in a liquid state by way of one or more rigid or deformable tubes which extend from the outside into the spaces between neighboring panes . at the same time , one or more additional tubes establish one or more paths for expulsion of air from such spaces . the panes can be pivoted , tilted and / or turned in the course of admission of plastic material . the tubes extend through removable or permanently installed strip - or bead - shaped seals which are disposed between or surround the marginal portions of the panes and seal the spaces between the panes from the surrounding atmosphere . the plastic material can be admitted in metered quantities , especially for the production of a long series of identical laminates .
