Abstract:
1. A Method for manufacturing a floor panel, wherein said floor panel is composed of a plurality of layers, said plurality of layers comprising one or more basic layers, a top layer forming a decorative surface and a panel top side and at least a sound-absorbing layer integrated into the floor panel and located between other layers of the floor panel; said sound-absorbing layer being a compressible, vibration absorbing material; said method comprising the steps of: providing said one or more basic layers; providing said sound-absorbing layer; manufacturing a composed plate of a size larger than said floor panel at least by providing at least said one or more basic layers and said sound-absorbing layer on top of each other and by mutually attaching at least said one or more basic layers and said sound-absorbing layer; wherein at least one of said basic layers being situated below said sound-absorbing layer; providing said top layer forming said decorative surface above said sound-absorbing layer, such that the sound-absorbing layer is located between said top layer and said basic layer; subsequently forming several floor panels from said composed plates; subsequently forming mechanical coupling parts at one or more edges of said floor panels; said mechanical coupling parts enabling vertical as well as horizontal locking between coupled similar panels; wherein said attaching involves fixing one or more of said sound-absorbing layer and said basic layers upon each other by melting one or more of said sound-absorbing layer and said basic layers by heating the one or more layers into a molten state at their upper surface and, subsequently bringing them together and adhering them with other layers.
