ABSTRACT:
A band finishing tool having a scissor-type mechanism utilizes a sliding pawl to hold one side of the buckle. The other side of the buckle is held along the edges of by buckle holding members to allow the free end of the tab to be folded over and engage the outside band diameter. The sliding pawl is mechanically coupled to the scissor-type mechanism. A rigid rollover member is mechanically coupled to the sliding pawl by way of a coupling spring. Initial squeezing of the scissor-type mechanism causes the sliding pawl to engage the buckle. Further squeezing of the scissor-type mechanism causes the rollover member to move laterally with respect to the pawl. This movement causes the tab to be folded over the buckle. The tool also includes a slot for prebending the leading edge of the tab at approximately a 45.degree. angle with respect to the band axis.
