<p>An article, e.g. a mat or belt pad, includes a flexible backing layer (3) having a pile (4) of thermoplastics material. A design is applied to the mat using a thin and flexible thermoplastics sheet (5) which is secured to the mat by high frequency welding in selected areas (7) which become recessed into the pile. A brass welding die is used which removes a peripheral area of the sheet (5), and the die may be profiled to form embossed regions (8) on non-bonded areas of the sheet. The non-bonded areas are supported by the pile (4) so that very intricate embossed shapes and profiles can be achieved.</p> |
