Abstract

A carpet or like covering is fastened to a floor or like support surface by a sheet comprising a thermo-fusible material interposed between the carpet and floor. A field of vibrations suitable for heating the thermo-fusible material is applied to the exposed face of the carpet and the source is moved over the extent of the sheet.

Claims

1. A method of fixing a covering sheet to a surface of a support having a surface area at least as large as the covering sheet, comprising spreading over an entire area of the surface of said support substantially equal to the area of the covering sheet a layer including hot melt glue and a material capable of being heated in response to an induction field of vibrations, arranging the covering sheet on the layer so as to sandwich the layer between the support and the covering sheet, generating through the covering sheet an induction field of vibrations having an area of at least one square decimeter and substantially less than the area of the covering sheet, and displacing said field over the entire covering sheet to cause the entire covering sheet to be evenly glued to the support.

2. A method in accordance with claim 1, wherein the layer is formed integral with and coextensive with the covering sheet and the layer and covering sheet are applied to the support at the same time.

3. A method in accordance with claim 1, wherein the layer is formed by sprinkling over the surface of the support a hot melt glue powder containing elements of said material that are heated by an induction field.

4. A method in accordance with claim 1, wherein the layer is formed by at least one sheet of material that is heated by an induction field and that is coated with said hot melt glue.

5. A method in accordance with claim 4, wherein the material is aluminum.

6. A method in accordance with claim 1, wherein the field is generated by an induction coil supported on a shoe that is moved over the covering sheet.

7. A method in accordance with claim 6, wherein pressure is applied to the covering sheet by pressing the shoe onto the covering sheet as it is moved over the covering sheet.

8. A method in accordance with claim 1, wherein the support is a floor or wall of a building and the covering sheet is carpeting.

9. A method in accordance with claim 2, wherein the support is a floor or wall of a building and the covering sheet is carpeting.

10. A method in accordance with claim 3, wherein the support is a floor or wall of a building and the covering sheet is carpeting.
