ABSTRACT:
Sheets of paper are commonly held together with a spiral coil, which coil is inserted by a machine with at least one rotating spindle thereon. The spindle receives a spiral binder in a male to female relationship. As the spindle rotates the spiral binder, the spiral binder feeds into a stack of sheets having the appropriate apertures to receive the spindle and bind the pages together.
