Overview thread sealing
The bookbinding method "thread sealing" makes use of special sealing threads, which are stitched through the spine of a signature during folding. Exposed to pressure and heat, the thermoplastic part of the thread ends, which stick out of the spine, adheres to the signature and assures a strong attachment of its single pages.
Afterwards, the signatures will be gathered for adhesive binding. This guarantees a strong hold of the signatures among each other. There is no need for milling prior to binding.
Advantages of thread sealing
- Time and ressource saving:
Thread sealing takes place directly within the folding process.
- High strength:
The adhesive surface is broader than the one of a usual adhesive binding.
- Flexible spine:
Books bound by thread sealing technology lay very flat.
