Headbands:
Headbands function as decorative pieces. The back is lined up using different Methods of lining up. However, the different methods of lining up have one thing in common, that is, smoothening of the surface of the spine by gluing a soft kraft paper over it.
Hollow Backs:
Hollowbacks help save the spine from cracking. This kind of back is achieved by marking a kind of `tube' with heavy wrapping paper. A paper three times the width of the spine is taken and one thickness is glued with the spine and two thicknesses apart from the spine.
The binding is covered either wholly or partially by leather, cloth or paper. All the above processes described so far are known as`forwarding'.
