CLEANING AND RELINING THE TEXT BLOCK SPINE
Depending on the condition of the text block spine, the spine lining paper and the crash can be removed before sewing.
If only one or two signatures are separated or in need of repair, it might be easier to punch sewing holes through the spine lining materials and sew directly through them.
If several signatures are affected or if the spine lining materials are in poor condition, remove them and the original sewing threads, then resew the volume, and reline the spine. Relining the spine is discussed in a separate post.
Any complete book repair should include cleaning the text block, resewing the text block, and relining it. Some books may not warrant this full treatment. In that case it is possible to resew through the old spine linings.
