DEFINITION

Classification: 412/42

Singular ring or ringlike element applier:

(under subclass 38) Apparatus specially adapted for applying a fastener in the form of a single annular element limited for insertion into a single fastener receiving hole of the sheets(*), signatures(*), or quires(*).

(1) Note. The fasteners of this subclass are restricted such that only one fastener can bind only one hole per fastener so that a multiple hole set of sheets(*), signatures(*), or quires(*) will require multiple fasteners to complete the binding operation.
