Abstract
The present invention provides a method and apparatae used to prepare a shaped and molded multilayered article formed from a heated thermoplastic sheet and a first plastic sheet that are driven into melt-bonding contact by a stream of gas. The method involves applying a stream of gas () against the first surface () of a first plastic sheet () so as to drive a second surface () of the first plastic sheet against and into contact with the first surface () of a heated thermoplastic sheet () as the heated thermoplastic sheet is formed (e.g., extends downstream from the sheet slotof a sheet die). The second surface of the first plastic sheet is defined by a thermoplastic layer. The heated thermoplastic sheet has a temperature that is sufficient to melt-bond the thermoplastic layer defining the second surface of the first plastic sheet and the first surface of the heated thermoplastic sheet together, thereby resulting in the continuous formation of a heated multilayered thermoplastic sheet () having a thermoformable temperature. The second surface () of the heated thermoformable multilayered thermoplastic sheet is brought into contour matching contact with the interior surface () of a first mold portion (), and cooled thereby resulting in formation of the shaped multilayered article. A sheet molding apparatus (), a sheet guide apparatus (), and fluid management structures () (e.g., storm/waste water management chambers) prepared thereby, are also provided with regard to the present invention.
