ABSTRACT:
This invention relates to a method of producing interior material of corrugated cardboard used for a ceiling of a car, for example.
Corrugated cardboard base material is plasticized by being heated and moistened while in a flat plane. Thereafter, the corrugated cardboard base material thus plasticized is pressed in a forming die having a low temperature such as a room temperature to be shaped in a predetermined manner. Afterward a covering sheet is disposed thereon having a thermally melting sheet provided thereon so as to be faced toward the corrugated cardboard base material thus shaped, they are pressed in the forming die to melt the thermally melting sheet by the preheated shaped corrugated cardboard base material to bond the covering sheet to the corrugated cardboard base material so as to produce interior material.
