How do traditional bows tie rubber bands?

First of all, correct a misunderstanding that bowstring is not a rubber-band bow. The energy of bowstring comes from the rebound of bow piece. Bowstring materials must be tough but inelastic, and rubber bands are absolutely not acceptable.

There is a special winding method for strings, but generally speaking, two bundles are combined into one bundle, and the upper and lower chords are set aside and wrapped with a string protector.
