Abstract
Abstract A stitcher including an anvil 104, a former 105 for forming a length of cut wire about the anvil 104 into a staple, and a driver 106 for driving the staple. The anvil is retractable and acts as a support for the staple during driving. The anvil is locked against movement during forming, and movement of the former 105 acts to release the anvil to perm it it to move out of the path of the driver 106 during driving while supporting the staple. (Figures 2 and 5.)
