<p><P>PROBLEM TO BE SOLVED: To provide a method of laying a covering sheet in which positioning can be easily made when laying and spreading a nonwoven fabric and an impervious sheet in piles, moreover, after the positioning, the nonwoven fabric and the impervious sheet are each other made into a contact opposite state by high friction. <P>SOLUTION: The method of laying a covering sheet is characterized as follows. A low friction sheet material 15 is spread to cover the upper surface of a nonwoven fabric 9 after spreading the nonwoven fabric 9, an impervious sheet 7 is spread on the low friction sheet material 15 which has been spread, the end edge of the impervious sheet 7 is made to meet the end edge of the other adjoining impervious sheet 7, performing the position adjusting, and the end edges mutually adjoining each other are joined, then, the low friction sheet material 15 is removed from between the nonwoven fabric 9 and the impervious sheets 7, and the nonwoven fabric 9 and the impervious sheet 7 are made as laminating arrangement. The impervious sheet 7 has an uneven surface 13 on the surface which counters the nonwoven fabric 9, which becomes high friction contact to the nonwoven fabric 9, and thereby the shift is inhibited. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
