    The invention relates to an arrangement for advancing a continuous strip of mutually integrated nails to the nail driving section (5) of a nail driving apparatus provided with a safety-catch device (24) and a nail strip magazine, and to hold the nail strip in the nail driving section. Single nails are stripped from the nail strip in the nail driving section by means of percussion and driven, in conjunction therewith, into the workpiece to be nailed. The magazine (6) incorporates a nail strip accommodating strip guide path (7) which adjoins the nail driving section (5) and in which the nail strip is held biassed towards a nail driving location in the nail driving section (5) by strip feed means (17, 18) located adjacent the strip guide path and engaging the nail strip located therein. The nail driving location is constructed in a manner to prevent a lone, unattached nail from twisting or turning therein. For the purpose of positioning the foremost nail in the nail strip in an exact position in the nail driving location (this foremost nail being the next in line for separation/driving into the workpiece) there is provided a rotatable nail positioning element (35) which is journalled for rotation and sideways movement in the nail driving section (5) and which is capable of being brought into engagement with the nail strip. The safety-catch device (24) is movable relative to the nail driving section and is held in a forward safety position by means of a coil spring. The safety device presents a latching surface (31) in the region of the positioning element (35), and arranged between the latching surface and the nail positioning element is a movable latching element (38). As the safety-catch device (24) is retracted (to its nail firing mode) the latching surface (31) is urged against the spherical latching element (38), which in turn moves the nail positioning element (35) into position-fixing latching engagement with the nail strip, in a region thereof immediately behind the foremost nail located in the nail driving location.

    The device comprises a housing 1, a nailing section 2 fixed thereto with a housing part, a magazine 3 for placing a nailing strip (not shown) in it, which is connected to section 2 at a right angle to the nailing direction, safety locking means 4 To install the device into an inoperative position and the plate 5, which with the help of bolts 6 rigidly fastens the nailing section 2 on the housing 1. The nailing section 2 with the casing part is designed as a guide 7 for moving the nails drum 8, a cylindrical part 9 with teeth protruding on its side surface mounted on a shaft 10 whose axis is parallel to the axis of the shock rod 8 and the tooth of part 9 with the surface of the guide 7 for contacting nails and centering them along the axis 11 of the guide 7, which is located in the groove 12 of the casing part, which surrounds the cylindrical part 9, can be moved along its axis by the holder 13 and the spherical element 14 installed therein in contact with the teeth of the part 9
    The magazine 3 is designed as a guide T5 with a longitudinal channel 16 for accommodating a nail nor- stud therein, the holder 17 of the magazine 3, one end 18 of which is connected to the guide 15 and the other 19 to the case of the nail band feed unit 1P. 2 driving nails from the winding means 20, placed in the guide 15 of the tangled elastic belt 21, of the segment hinge 22 with the Fixer 23 in its position at the free end of the guide 15, which is connected to the tool 20 with the strap 21 tnik 22 handles 24 with a plate 25, nap ION parallel to the guide 15 to the section 2 for nailing.
    In addition, the device comprises a holding magazine 6 in the casing part of section 2, a stopper spring 26 attached at one end to the guide 15, and a free end abutting against the beveled surface 27 of the holder 17 of the magazine 3,
    The safety locking means 4 is arranged to move along the axis of the impact rod 8 in the form of a guide 7 of a sleeve 28 spanning a free edge, successively connected elements 29 and 30, one element 29 of which is installed in a guide 31 connected to housing 1, and another element 30 is connected to the safety bar 32 of the device. In this case, the element 29 at the edge facing the shock rod 8, with its surface 33, which is beveled towards the rod 8, contacts with the spherical element 14,

    the nail bar, which is located in the guide 7, and means for preventing the nail from the last nail from the nailing strip, which is made in the form of a permanent magnet 38 radially mounted in the guide 7, and in element 30 a slot 39 is made, designed for placement in it of a plate 25 in the absence of a nailing strip in the device.
    The device works as follows.
    Using the handle 24, the follower 22 is moved to the free edge of the guide 15 of the magazine 3 and is secured by the lock 23 to it. In the longitudinal channel 16 of the store 3, the nailing strip is placed, releasing the binder 22 from fixation. At the same time, the binder 22 by means of the tool 20 and the traction elastic belt 21 moves the nailing strip along channel 16 until its first nail is placed in guide 7.
    The device with the sleeve 28 is abutted against a blank (not shown) for hammering nails, and pressing the device. At the same time, the spring 34 is compressed. In the process of movement, the surface 33 moves the spherical element 14 into position between the teeth of the part 9 and thereby performs with high precision a combination of the axis of the nail located in the guide 7 with its own axis 11. When the guide 7 the free end touches the surface of the workpiece, its axis will be aligned with the axis of the nail, and the serially connected elements 29 and 30 connected to the sleeve 28 through the rod 32 turn on a drive (not shown), which with the help of the impact rod acts on the nail, Nail s via the base plate 37 is sheared from the nail strip and clogging in the workpiece,
    j
    The sequence of operations for hammering the following nails is repeated.
    The last nail is held in the guide with a permanent magnet 38 before driving into the workpiece.
    When the nailing strip is fully used, the plate 25 is automatically positioned in the slot 39 and it becomes impossible to operate the device, since the movement of the sleeve 28 is impossible and, therefore, the drive of the device cannot be activated.
    Bringing the device into operation
    state requires placement in it. new nailing strip.
