<p>The upright glass sheets are clamped between L-sections locked together. The two independent rings enclosing each packet (1,2,3) are each in two L-sections, and incorporate a bottom supporting portion (32) and a vertical profiled portion. The frame incorporates two or more rings (6,7,8) of different sizes, to accommodate sheets of different sizes. The vertical members have fixing devices (22,23) all at the same height, to secure adjacent packets to each other. The rings for the longer packets can be duplex ones, made in two parts joined by cross-struts.</p> |
