saddle sewing
The process of sewing a section, e.g., a
periodical issue or pamphlet, through the center
fold by means of thread. The term "saddle" derives
from the SADDLE of
the machine. Saddle sewing affords full
openability of the section, i.e., to the gutter of
the binding margin. Saddle sewing may also be done
by hand, usually employing a figure-eight stitch,
but it is more often done by machine, usually one
which has the capability of varying the length of
the stitch. Cf: SADDLE
