COVER LAYER AND PANEL WITH SOUND-ABSORPTION PROPERTIES AND METHOD FOR PRODUCING SAID LAYER AND PANEL

摘要

The invention relates to a cover layer and a method for producing said layer (2). According to said method, a layer of adhesive (6) is applied to a coating (4), the layer of adhesive (6) is partially activated and bonds to the coating (4) and the bonded coating (4) and adhesive layer (6) are then perforated (8). The invention also relates to a sound-absorbing panel and an associated production method, according to which channels are configured in a support panel (20), connecting a first face (24) of the support panel (20) to a second face (26) of the support panel (20). The first face (24) of the support panel (20) is then provided with grooves (28) and the grooves (28) and channels (22) are positioned in relation to one another in such a way that at least one section of the channels (22) is connected to at least one respective groove (28). According to the invention, the grooves (28) are aligned in a first direction, said direction running at an angle greater than 10°, preferably at an angle greater than 30° and in particular at an angle of 45° to the respective edge of the faces (30, 32) of the support panel (20). In addition, a cover layer (2) can be placed on the support panel (20) that is provided with grooves (28).
