1506880 Air-cushion supported conveyer belts C O JONKERS 10 July 1975 [11 July 1974] 29144/75 Heading B8A A belt 3 supported on a cushion of air, e.g. as in Specification 1,341,897, is shaped preformed or differentially reinforced so as to remain closely spaced from its support surface 1. The belt may be thicker in the central region of its cross-section (Fig. 3, not shown), it may be preformed to an arcuate shape (when under no load and weightless conditions) (Fig. 2, not shown), and it may have reinforcements which are more densely spaced in the region of its cross-section (Fig. 4, not shown). |
