1534597 Endless conveyers SAINT-GOBAIN INDUSTRIES 16 Sept 1976 [22 Sept 1975] 38370/76 Heading B8A Workpieces A, e.g. tubes, are conveyed through a hot gas heat-treatment zone at successive levels and in successive opposite directions, the workpieces being rolled the while about axes normal to their direction of movement. As shown the tubes are rolled along perforated plates 3 by bars 4 carried between a pair of endless chains 5. The upper and lower runs of the chains are used to convey the tubes in successive different directions. Transfer between the upper and lower runs and from one conveyer to the next is by gravity. The plates 3 may be inclined to the horizontal (Figs. 4 and 5, not shown). A particular application described is the heating of resin bonded fibrous shells in a gas-fired oven in order to harden the resin (Fig. 1, not shown). |
