Abstract
The present invention provides a restored winding core and a method for manufacturing the same, wherein at least one discarded winding core is first collected. At least one of the extremities of the discarded winding core is internally ground on a predetermined grinding distance to remove the crimping portion and provide a ground portion thereon. The ground portion defines a female joint socket extending at the corresponding extremity of the discarded winding core for providing a machined core extremity. The method also comprises the step of providing at least one hollow insert tube diametrically snugly fitting into the female joint socket. The at least one insert tube is inserted inside the corresponding female joint socket for providing a restored core extremity. The present invention thus allows to restore the damaged extremities of a winding core which can then be reused as a new winding core of the same length. The present method also allows to join several discarded winding cores end to end for providing a restored winding core of a longer length.
