ABSTRACT:
A method of laminating a plastic sheet onto a surface of a hollow body is disclosed.
The method of laminating a plastic sheet onto a surface of a hollow body includes the steps of loading the hollow body into the female die, securing the plastic sheet in a clamping means, heating the clamped sheet to its softening temperature, moving the clamped heated sheet into registry with a male die and the female die, sealing one die of the male die and the female die to one member of the clamping means and the clamped heated plastic sheet to define therewith a sealed chamber, moving the male die toward the clamped heated sheet to form the clamped heated sheet about the male die, moving the male die and the clamped formed heated sheet against the surface of the hollow body in the female die, and applying fluid pressure to the clamped formed heated hollow body to transfer the clamped formed heated sheet to the surface of the hollow body.
