Covering


The covering operation is done in the last of the book binding process. Cover
of the book contains the name of the book, author, and publisher. It is made
attractive by printing in multicolours. Cheap edition and general textbooks
are covered with thick printed card sheets. High quality books are covered
with boards. There are two types of covering process namely Paper back edition
and Board cover edition also called hard bound book.


Paper back edition:- In paper back edition, the book is covered with a thick
card or paper. The centre part of the book cover is creased according to the
thickness of the book. Paste is applied on the spine of the book and in the
centre part of the cover. The spine of the book is placed on the cover and fixed
with the book. Then paste is applied to both sides of the end papers and pasted
with the cover of the book. When it is dry, the edges are trimmed in the last.


Board cover edition (Hard bound books):- Books that need long life are covered
with boards. Board covering process is divided into the following processes:




  1. Preparation of the cover: The cover of the book is prepared separately.
    Two pieces of boards for each book are cut 5 mm larger in the length and
    same size in the width of the book. The covering material of the boards is
    also cut 15 mm larger in the length, and width plus spine of the book. A
    thin layer of paste is applied on the rough side of the covering material.
    Both pieces of the board are placed on it and pasted with turning in, the
    excess part of the covering material. A thick strip of paper is pasted on
    the covering material left for the spine of the book.




  2. Preparation of the book: First the book is trimmed at the head, tail, and
    fore edge of the book. Thin liquid glue is applied on the spine. Rounding
    and backing operations are done for the spine of the book. A strip of cloth
    is pasted on the spine with overlapping about one inch on both sides of
    the book. Headbands are fixed on both sides of the spine.




  3. Setting cover of the book: The spine of the book is placed in the centre of
    the prepared cover. Paste is applied on both sides of the end paper and
    pasted on the board of the cover. Paste is also applied in the spine for
    tight back book. For hollow back book, a strip of paper is pasted on the
    spine of the book and the spine remains unpasted with the cover.
