发明名称 RESTORED WINDING CORES, METHOD AND APPARATUS FOR MANUFACTURING THE SAME
摘要 <p>The present invention provides a restored winding core and a method for manufacturing the same, wherein a plurality of discarded winding cores is first collected. Each extremity of each core is internally ground on a predetermined grinding distance to remove the crimping portion and provide a ground portion thereon defining a female joint socket. The method also comprises the step of providing a plurality of hollow insert tubes diametrically snugly fitting into the female joint sockets. Each insert tube is inserted inside the corresponding female joint sockets of two respective cores for joining the two cores end to end to provide an endless recycled master core having an internal surface continuity therein. A finishing fold is spirally wound around the recycled master core and therealong for providing a restored winding core that can be cut to any desired length. Advantageously, the restored winding cores can be continuously manufactured.</p>
