A clinching mechanism has an anvil composed of first ( ), second ( ) and third ( ) plates arranged in a spaced apart stack with the second plate ( ) positioned between the other two. The plates ( ) are mounted on a housing ( ) so as to be slidable relative thereto and the second plate is also connected to the first and third plates ( ) so as to be slidably movable relative to said first and third plates between a first aligned position in which at least one edge of the first, second and third plates ( ) are aligned to form and anvil face and a second retracted position in which the second plate ( ) is retracted from the anvil face. With the second plate in its aligned position, a staple to be clinched in received with its two legs ( ) on either side of the second plate ( ), the second plate operating to guide the legs ( ) into engagement with associated clinching device ( ) positioned between the first and second, and the second and third plates. Once the staple is located, the second plate ( ) is moved to its retracted position in which it is partially retracted from between the legs. The clinching device are then operated to fold the legs ( ) towards the staple crown and also urge the legs ( ) laterally towards each other, the retraction of the second plate ( ) permitting the legs ( ) to be clinched into close alignment with each other.
