Abstract
An improved closure for books characterized essentially by the fact that the inner face of the rear pulp comprises a transverse recess in the form of a rigid, die-cut T-shaped plate whose transverse section is of a smaller width than that of the said aforementioned recess to allow the sliding of said piece in the recess, its limited path being left inside thereof and said part comprising its outer end turned in arc to be anchored on the main paste in the introduced position of the piece constituting closure. (Machine-translation by Google Translate, not legally binding)
