<p>A powered draw belt (10) of a belt conveyor (6) for conveying glass sheets (2) has a main supporting surface (13), and is fitted with a suction retaining device (18) for securing a glass sheet (2) to the draw belt (10); the retaining device (18) having at least one hollow body (20; 30) at least partly covering the main supporting surface (13); the hollow body (20; 30) defining a supporting surface for the glass sheet (2), and having at least one elastically deformable portion (26) spaced apart from the main supporting surface (13) to define, with the main supporting surface (13), a variable-volume chamber (25; 33) connectable to a suction source.</p> |
