Abstract
An apparatus for manufacturing a magnetic disk wherein a center core having an adhesive substance previously applied thereto is adhered to a magnetic sheet. The apparatus includes a holder having a center core retaining member extending therefrom for receiving and retaining the center core, the holder being rotatable such that the retaining member rotates about an orbital path; a core feed station, disposed along the orbital path, to which the center core having the adhesive applied thereto is fed, the center core being received by the retaining member at the core feed station; an adhering station disposed along the orbital path at a position downstream of the core feed station for adhering the center core to the sheet; and an annular housing substantially surrounding the orbital path an through which hot air is circulated so as to partially dry the adhesive applied to the center core. The apparatus further includes a station disposed along the orbital path for supplying center cores having a double-sided adhesive tape applied thereto so that center cores can be alternatively adhered to the sheet using such tape.
