Production Line: Display Shell Line

Twelve machines covering sphere casing, hole punching, delay fuse cutting and insertion, wrapping and finishing. Shell wrapping is the stage most plants still do by hand, and it is the stage where hand work shows up in the break. The wrapping machines on this line hold consistent tension across the whole sphere, which is what gives a symmetrical break at altitude. This line grew substantially in the current catalog edition. If you looked at an earlier version, look again.
