<p>PCT No. PCT/GB84/00288 Sec. 371 Date Jul. 26, 1985 Sec. 102(e) Date Jul. 26, 1985 PCT Filed Aug. 20, 1984 PCT Pub. No. WO85/01098 PCT Pub. Date Mar. 14, 1985.A high-temperature, rapid-cycle pin oven for the curing of coatings on hollow container components, includes an oven unit (2) whose housing (14) is divided into three compartments interconnected by internal explosion relief panels (136,142,144). One of the compartments (36), designed for a normal working pressure in the range 1 to 1.01 atmosphere, has a light explosion-relief panel (132) which provides primary pressure relief to atmosphere while ensuring that if the internal panels blow out, the entire interior is vented to atmosphere. This panel comprises a light casing (202) with thin tinplate bursting diaphragms (210) in the bottom, overlaid by a light, absorbent mattress (220), and a light top cover (222) which can blow out. A perforated hot air delivery screen (38) forms one wall of the narrow working chamber (34) and comprises a number of plates removably and replaceably fastened to a frame (72) fixed in the housing.</p> |
