end sheets

The image above shows one type of end sheet used for sewn text blocks, of double folio construction and with a cloth hinge. Another variety uses a single folio with the paste-down added as a separate sheet. However, this leaves both the sewing and usually a narrow strip of hinge cloth exposed to immediate view on opening the book. Besides added strength, the double folio type offers the aesthetic advantage of concealing the hinge cloth and sewing, requiring that one leaf must be turned to reveal the latter.

This illustration shows a type of end sheet used for adhesive-bound text blocks. It is made of a single folio, attached by the stretch cloth hinge to a single leaf. The folio is reinforced with a captive strip of mylar between its leaves, which are glued together to form a double-thickness paste-down.
