The charged caps are thenpassed to a machine similar to Fig. 3633, in whichthe punch moves on a stationary guide across theplate, and, entering each hole, lines the caps in suc-cession with the tin-foil, the plate being moved aseach row is completed. A second punch may beused to apply a drop of varnish after the lining isin place.
