METHOD FOR CONNECTION OF CELLULAR SOUND-ABSORBING PANELS Russian patent published in 2012 - IPC B29C67/20 B29C65/56 B31D3/02 

Abstract RU 2469852 C2

FIELD: construction.

SUBSTANCE: invention relates to the method of connection of the first sound-absorbing panel (2), having a honeycomb cellular structure, with the second panel (21). The method includes the following stages: at least one thorn is inserted (5, 8), having the shape matching with cells (3), at least into one cell (3), located near a connection edge (6) of the sound-absorbing panel. Then the connection edge of the sound-absorbing panel is rolled with a roller (12), the connection edge of the sound-absorbing panel and the connection edge (6') of the second panel are joined. Afterwards both panels are joined to each other with the help of a binder.

EFFECT: invention provides for specified acoustic characteristics due to elimination of collapsing, damage and violation of cells integrity during their connection when arranged in two panels.
