发明名称 Carpet with fusion-cut through bore and its manufacture method
摘要 In a carpet having a through bore, the through bore is formed by fusion-cutting. A hem member is welded integrally to the areas of a napped portion and a base cloth at the circumferential edges of the through bore. This prevents the threads of the napped portion existing at the circumferential edges of the through bore from fraying and also keeps such areas from being stained with oil or the like. Also, a method of welding said hem member to said base cloth is disclosed which comprises: laminating a thermally weldable synthetic resin film for hemming on a carpet, punching out a through bore in the synthetic resin film by means of a high frequency wave, and at the same time welding the hem member integrally to the wall edges of said punched through-bore. The simultaneous operation-welding of the hem member and punching of the through bore-provides a carpet quite easy to form and less expensive.
