Apparatus for centering and attaching a reinforcing ring to a floppy disk

In apparatus including a force translating mechanism mounted for movement to and from a resiliently mounted receiving member, for cooperatively positioning and attaching a reinforcing ring in coaxial relationship to a flexible recording disk, the improvement comprising:

• (a) a cylindrical positioning member mounted for axial movement relative to said force translating mechanism and having a first reference surface corresponding to the inner diameter of such a reinforcing ring and a second reference surface, concentric with and smaller than said first reference surface, corresponding to the inner diameter of such a flexible disk, said cylindrical positioning member, in response to movement of said force translating mechanism for attaching the reinforcing ring to the flexible disk, being moveable axially relative to said translating mechanism between (1) a first position in which said first reference surface causes said force translating mechanism to carry the reinforcing ring in a predetermined disk-attaching position, and (2) a second position engaging said receiving member in which said second reference surface causes the flexible disk to be located in a position concentric with the disk-attaching position of the reinforcing ring;
• (b) said force translating mechanism, said positioning member, and said receiving member mutually cooperating during movement of said positioning member between its first and its second positions, to bring the reinforcing ring and the flexible disk into a bonding relationship during movement of said force translating mechanism toward said receiving member.
