<p>A nail feed mechanism is provided with a front feed claw (9) and a rear feed claw (10). Disposed forwardly of the claw (10a) of the rear feed claw (10) is an abutment (10b). The abutting surface of the abutment (10b) for abutting connection nails is wider than the inter-nail gap so that it cannot enter between nails. When the front feed claw (9) retracts to arrest the terminal nail (TN1) in the first row, the abutment (10b) and the pawl (10a) advance into the nail passageway, with the abutment (10b) entering between the terminal nail (TN1) in the first row and the front nail (FN2) in the second row, the claw (10a) entering behind the front nail (FN2) in the second row. After nail feeding, the feed claw retracts, with the abutment (10b) and the pawl (10a) moving across the lateral surface of the connection nail (N2) in the second row to return to the retracted position, the front feed pawl (9) engaging the front nail (FN2) in the second row to continue nail feeding.</p> |
