A machine includes a conveyer that is movable along a generally linear path. Two fiber chutes deliver fiber to the conveyer. First and second heaters and compression devices are used to provide different densities to the different fiber layers. A first heater and first compression device is used to compress a first fiber layer prior to depositing the first fiber layer onto a second fiber layer. The compressed first fiber layer and uncompressed second fiber layer are conveyed to the second heater and second compression device where both layers are heated and compressed. Aesthetic layer may also be applied to at least one of the layers. A third layer may be provided on the first layer opposite the second layer. The compression devices are adjustable by an actuator for processing fiber batts having different thicknesses on the same machine. Adjustable trimmers are used to trim the sides of the continuous fiber batts and cut the batts to a desired width, height and length.
