loose pages

Detached single leaves can be reattached to the text block by hinging or tipping depending on the structure of the text block.

Since each leaf of a sewn text block is one half of a complete folio, always make sure the other half of the folio is well attached to the text block. If the second leaf is loose, both leaves must be repaired.
Two detached halves of a folio can be re-attached by hinging or tipping, or as a partially detached signature (separate post).
