This method heat-softens the cutting edge of thermoplastic material with a flat σ surface, vacuum-forms it using a test mold with an embossed pattern, and transfers the embossed pattern τ onto the mold surface at the same time as molding. With this method, the shape Q) by,

Jlc was applied to the skin sheet under normal temperature conditions using a test mold with an embossed pattern τ carved on the mold surface.
After the nitride forming process, the sheet is removed by vacuum suction.

? ! -It takes a lot of effort to make it! ! Use vacuum molding mold 5τ. The surface of this vacuum mold has a surface skin 1 with opposing unevenness /b wedge-like 2: g 4', and vacuum suction holes 6 with small σ are opened in the surface of the mold. First, the sheet A with a smooth surface is heated to the temperature of a normal vacuum bottom shape (Fig. 6). At this time, the sheet A is heated to the temperature of the vacuum mold 5 (Fig. 6). Although some degree is transferred, the thread twist 4 of the stitch 6 does not appear.

At this time, the material and thickness of the sheet to be used during vacuum forming (m5nm), 5 nm, or porous dust, should be determined as appropriate.

．． It is best to resheet the sheet at about 140 to 180 degrees Celsius in the first step. Heat it up [about 0200 to 260 degrees Celsius, also, this re-771] Heat / Blow hot air τ with a hot jet gun on the 8th method [Effects of the Invention] From the above explanation, it is impossible to solve the problem by using any method such as instant heating with a flame such as a burner. It is now possible to transfer embossed patterns with good re-visibility.
