APPARATUS AND METHODS OF FORMING SOUND ATTENUATING LAMINATES HAVING FIBER AND MASS LAYERS

摘要

Apparatus and method for forming a sound attenuating laminate (10) that has a decoupler fiber layer (12) and a mass layer (14) in opposing relationship with each other. The decoupler fiber layer (12) and mass layer (14) of the laminate (10) are heated to the selected temperature in substantially the same amount of time via a hot air source (36) and a heated platen (34), respectively. The heated laminate (10) is conveyed to a mold (40) and formed into a predetermined three-dimensional configuration via the mold (40).
