At present, most textiles are produced and processed on the basis of cloth rolls. There are generally two types of cloth rolls. One is the cloth roll containing a core rod. The other is the cloth roll without a core rod. Although this kind of cloth roll does not need to disassemble and assemble the cloth supply machine when in use, because the cloth roll does not contain a core rod, it is relatively soft, and an additional mechanism needs to be added.
