With the matrices aligned and the space bands set to the correct measure, the machine then ‘locks up’ the line with great force and the plunger injects the molten type metal into the space created by the mold cavity and the assembled line. The machine then separates the mold disk (carrying the freshly cast slug), the metal pot, and the first elevator. The mold disk then turns to present the line at the ejecting position, in the process passing by a knife that trims the base of the slug to type height (0.918″ on US machines). The slug is then forced through an adjustable pair of knives to trim the slug to the proper body height before sliding down into a ‘galley’ of finished lines next to the operator. Depending on the model of machine, the mold disk could have 4 (standard), 6, or 2 molds, giving the operator his choice of line lengths and body sizes.
