The series of matrices thus assembled in line forms a line matrix, or, in other words, a line of female dies adapted to mold or form a line of raised type on a slug cast against the matrices. After the matrix line is composed, it is automatically transferred to the face of a slotted mold into which molten type-metal is delivered to form a slug or linotype against the matrices.

In a book of fiction of a dozen different characters, the productive energy passes through a dozen different matrices before finding expression.
While the parts are in this position, the justifying bar Q is driven up and pushes the spaces or justifiers upward through the line of matrices until the line is expanded or elongated to fill completely the gap between jaws P, P.
This permits the composition of one line, the casting of another, and the distribution of a third to proceed simultaneously. The matrices pass through the magazine by gravity. Their release is effected by mechanisms shown in Figs. 5 and 6, which are vertical sections through the magazine, the keyboard, and intermediate connections.
