METHOD FOR FOLDING SECTIONS COMPRISING A HOLLOW BODY AND A COATING SHEET, AND RESULTING FOLDED SECTION |
摘要 |
<p>A method of forming a composite profile including a hollow body with approximately parallel opposite walls and a covering sheet fixed against a first one of the walls includes heating a portion of the composite profile to form a temperature gradient. A hot forming projection is then pressed against a second one of the walls so as to bring the first wall into contact with the second wall at a formed region. At least one section of the profile is then pivoted about the formed region so as to produce a folding line.</p> |
