A vacuum is formed on the second surface of the support, and portions the heated thermoplastic sheet are drawn through the perforations of the support and to the second surface side of the support. Thermoplastic attachment heads are formed on the second surface side of the support, from the thermoplastic material of the sheet that is drawn through the perforations. The thermoplastic sheet and the support are fixedly attached one to the other by means of the edges of the perforations being embedded in the thermoplastic material of the sheet drawn therethrough, and the thermoplastic attachment heads.
