A reactor plate assembly (111) for a fastener dispensing device (30) includes a metal reactor plate (113) mounted onto the distal end of a fixed support arm (35) for the device, the reactor plate including a flattened top surface (117) shaped to define a pair of elliptical, needle-receiving holes (123-1, 123-2). The reactor plate assembly (111) additionally includes a brush anvil (115) removably secured to the underside of the support arm (35). The brush anvil (115) includes four separate bristle clusters (127-1 - 127-4) that are retained within associated bores (141-1 - 141-4) in a block, with a first pair of bristle clusters (127-1, 127-2) projecting into one needle-receiving hole (123-1) and a second pair of bristle clusters (127-3, 127-4) projecting into the other needle-receiving hole (123-2). Each bristle cluster (127-1 - 127-4) includes a group of individual nylon bristles, the free ends of the bristles lying flush with the top surface of the reactor plate (113) to provide a planar support surface which can be penetrated by the needles (59-1, 59-2) of the device during the dispensing process. |
