Banded nails produced of different materials and with nails the heads of which are bent between 10 and 130 DEG , so designed that, when driving in nails, the large drive-in force exerted by certain drive-in tools, can be used to bend the head further. Between one bent end of a nail head and the nearest adjacent nail tip partial separation is brought about by a recess, the design and depth of which depend on the penetration resistance of the nail and requirements in respect of the nail band's stability. When rolling up the nail band, the connecting bridges between the nails are subject to bending. In addition, the rooling-up form changes in accordance with the different nail head angles. When driving in one nail at a time feeding motions are produced, which feed forward one nail at a time. The feeding motion actuates the unwinding of the nail bend. |
