发明名称 Paper reinforcing and repair rings
摘要 A reinforcement pad can be applied to sheets of paper, such as notebook paper. The reinforcement pad generally comprise a ring having a split region. The split region permits placement of the reinforcement ring around an object, such as the ring of a ring binder, without removing the sheet to be repaired or splitting the ring.
