ABSTRACT:
A coreless roll winder includes two sets of belts traveling in opposite directions. A cigarette of web material is formed, and the web is wound around the cigarette by the contact with the belts. The roll formed from the winding is transported to the downstream end of the belts and separated from the rest of the web.
