Abstract
A method for sewing together covering elements is provided, in which two first threads and a second thread are used in a sewing machine having sewing needle means. In operating the sewing machine, the covering elements are fed at a given feeding pitch, such that the two first threads are entwined about the second thread in each of needle holes formed by the sewing needle means in the covering elements. Those entwined three threads fill and close the needle hole, thereby preventing leakage of a liquid foaming agent at a foaming process for forming a foamed product integral with the covering elements. The sewing needle means may comprise one sewing needle, in which case, both two first threads are used in that one sewing needle, or alternatively may comprises two sewing needles, in which case, the two first sewing threads are respectively used in the two sewing needles.
