Document Type and Number:
Japanese Patent JPS6344392
Kind Code:
B2
Abstract:
According to this method a cellular core (1) is produced, having dimensions smaller to the prescribed dimensions and such size difference is compensated by applying on said core a fiber tissue (2). The space existing between the core (1) and the hull (3, 4) of the board, thus occupied by the tissue (2), is filled with foam in order to form, in the edge area of the core, a highly pressure resistent foam layer reinforced by the fibers, which perfectly binds the rigid hull (3, 4) of the board to the core.
