Closed Head

In binding and finishing, an uncut top of a signature produced by folding. During binding, the fold is slit open. Often, however, it is desirable to leave signatures uncut until binding is nearly complete; in thread sewing and saddle-stitching signatures that are uncut open more easily and quickly. Also known as a closed section or a closed signature.
