FRAME FOR FIXATION AND IMPREGRATION OF CELLULAR FILLER EXPANDED PACK Russian patent published in 2010 - IPC B32B3/12 

FIELD: process engineering.

SUBSTANCE: invention relates to devices designed to produced cellular filler (CF) for three-layer panels and enclosures used in various industrial branches. proposed frame represents a hollow parallelepiped consisting of two flat parallel frame jointed together by thrusts for tension members to rest thereon. Proposed frame differs from known designs in that lateral sides of every flat frame accommodate guide rods with seats for tension member ends to rest thereon, where above four angle pieces secured on every flat frame. Note that guide rod seta are arranged with spacing corresponding to that of cellular filler cells.

EFFECT: equal strength of CF, noise absorption by cellular structures.
