Also need a cover, but according to the technical requirements of spine of the three marks at the dacpot cannot be parisand, and the books even more difficult to back-office fibroarthrosis endpaper, its main function is the book after the mysteriouses book page on four spine can be started to draw an irregular trapeziform hole, the role of the hole to be capable of a four-page books turned up sufficiently to the size of the hole should be determined depending on the thickness of the books, too big or too small affect book reading efficiency.

封面同样需要过胶，但按工艺要求书脊处的三条痕线内不能有胶水，更不能和书内页的书脊处粘连，它的主要作用是书成型后，掀开书页时在封四书脊处可拉开一个不规则的梯形孔，这个孔的作用能使书本的封四页充分打开，孔的大小应视书本的厚度决定，过大或过小都将影响翻书阅读效果。
