Abstract
An apparatus for forming and driving staples in a single stroke includes a former (4) for forming staples from pre-cut lengths of staple wires, a forming block around which each staple wire is bent by the former, and a driver (3) for driving each formed staple into a workpiece. The former (4) and driver (3) each comprise a substantially flat plate, with the driver slideable within a cut-out portion (33) of the former, and with both plates having their two major surfaces in sliding contact with parallel, spaced apart, guide plates (5, 6). A common driving member (7) is linked to the driver (3) and disengageably linked to the former (4) by means of a retractable link pin (38). The driving member (7) is arranged to initially drive the driver and former together to form a staple around the forming block. Once the staple has been formed, the forming block is withdrawn from within the formed staple. The driving member (7) is disengaged from the former (4) at a predetermined point during the driving stroke after which the driving member drives only the driver (3), so that the driver moves relative to the former to drive the formed staple into the workpiece.
