Tightening hinges

Description:
When a text block is loose in its case, sometimes instead of replacing the cover, we can insert a white glue (polyvinyl acetate) along the length of the joint with a knitting needle. The book is then placed in a book press to tighten the adhesion of the text block to the case.
