Once the book has been
stitched together it is rolled and hammered to turn the flat spine
back into a rounded shape, which protects the sewing by reducing
the strain on it when the book is opened. The book is put
into the lying press, two large pieces of wood which are tightened
by means of wooden screws and a bar known as a ‘press pin’. When
the book is the correct shape it is covered by a piece of open
weave cloth called mull and a strip of thin strong paper known
as ‘kraft’ paper.
The book is rolled and
hammered into its rounded shape.
It is then put between specially-shaped
backing boards and lowered into the lying press.
The lying press screws are tightened.
The spine edges can then be shaped
over the backing boards with the backing hammer.
