Appeal No. 1999-2148 Page 9
Application No. 08/864,947
First, an impregnated bias-cut fabric layer 16 preferably with
its warp extending angularly with respect to the warp in sheet
15 and of a width just to fill remaining spaces between steps
5, 5' is applied (Figure 5) and in like manner succeeding
layers of bias-cut fabric 17, 18, 19 are supplied to fill the
spaces between steps 6, 6' (Figure 6); 7, 7' (Figure 8) and 8,
8' (Figure 8) respectively. Finally, outer layers of bias-cut
fabric 20, 21 (Figure 9), the outer one spanning the space
between steps 9, 9' formed by the covers, followed by a
slightly longer rubber covering sheet 22 (Figure 10) are
disposed about the entire assembly and successively cemented
in place to supplement the previous layers and enable a smooth
outer surface to be formed.
After Galloway's splice has been formed up and prepared
for curing by application of tape T (Figure 11) for
maintaining pressure against it and blanket A (Figure 12) for
minimizing escape of vulcanizing heat, dry steam preferably at
about 80 p.s.i.g. is introduced through duct 26 to mandrel
chamber 25 and circulated therethrough to exhaust duct 28 for
a suitable curing period. Upon completion of the vulcanizing
