Sleeve (book)

from Wikipedia, the free encyclopedia

In bookbinding, the sleeve refers to a flattened tube made of tough paper, which, glued to the spine of the book , creates an additional connection between the book block and the book cover . In this way, the finished book has a hollow spine.

The hanging of blocks on a sleeve is used especially for books of larger size, as it improves the opening behavior and thus brings with it a higher durability. However, the width of the sleeve has to correspond almost exactly to that of the book spine, because if it were narrower it would tear or come off when the book is opened.

Nowadays, cores can be manufactured and processed both manually and by machine. The corresponding operation is also called sleeves.
