<p>1,130,315. Endless conveyers. BADISCHE ANILIN- & SODA-FABRIK A.G. 18 Feb., 1966 [19 Feb., 1965], No. 7186/66. Heading B8A. [Also in Division B5] Radiant heaters 17 (Fig. 1) fuse the ends of laterally disposed tubular blanks gripped between opposed pairs 6 of endless conveyers by which they are carried over slide rails 3 whose spacing may be adjusted. In the form shown the conveyers consist of chains (6) (Fig. 2, not shown) equipped with straps (6b) gripping the blanks and guided by rails (8) . . . (11) cooled by watercooled bars (12). The heaters are radiant quartz tube heaters. The fused portions are subsequently cooled by endless steel bands (27) (Fig. 3, not shown) backed by water-cooled members (29) and engaging portions of the blanks partly protected from the radiant heat by being disposed in the gap (13) (Fig. 2, not shown) between the guides (10), (11). The fused portions are then formed by grooved rollers (41), (42) (Fig. 4, not shown). The forming rollers (41), (42), and the rollers carrying the cooling bands (27), (28) are biased against adjustable stops set in accordance with the thickness of the blanks. Before entering the heated region the ends of the blanks are trimmed by a rotary member 44. The spacing of the heaters 17 from the conveyers may be adjusted, and the heaters are preferably nearer to the conveyer at one end than at the other. The spacing between the slide rails 3 may be varied by a crank 5 controlling lazy tongs 4.</p> |
