In Figures 5 and 6 the strip I0 is provided with‘ 30

_
In the forms of the invention» above described,
the strips l0 and the ends of the arms engaging
the same are disposed preferably between one
cover of the book and the bound sheets although .
15 these portions of the binding may be disposed in .
the middle of the book between the sheets or po
sitioned at the rear edge of the bound sheets, if
desired. However, a neater binding is provided
and the covers can be opened back to back by
20 disposing the strip and arm ends beneath one
cover, and the assembly of the sheets upon the
, binder arms is also facilitated.
For this reason
the strips I0 and the engaging ends lld'of the
arms II when in contact with a cover'preferably
lie in a plane parallel with the covers. The strip
and interlocked ends of the arms therefore pref
erably lie in a non-r‘adial plane of the circle or
cylinder de?ned by the arms. Where the strip
and arm ends are to lie ‘midway of the bound
30 sheets or are ‘to extend rearwardly from the
bound edges of the sheets they are disposed in a
radial plane of the circle de?ned by the arms.
The arms and strips of the above described de
vices can be formed of relatively thin material
such as sheet metal. In order that the ring
shaped arms when formed of thin material shall
be sumciently rigid to retain their shape and
that rough edges shall be avoided, it is preferred
