Abstract
The present invention comprises a nail driving device with a magazine for nails held together in nail strips, with a nail transport device, wherein the nail strips are pressed in the direction of a fixed stop surface by means of a spring element, and moved in the direction of the exit channel of the device mouthpiece. In order to be able to work with nail strips in which the nail shafts are spaced apart, but rather lie shaft against shaft, it is provided that the nail transport device has a transport shuttle which can be moved in the longitudinal direction of the magazine using the piston rod of the feed cylinder, and which has a wedge-shaped nail strip separating element which is operative during the reverse movement of the shuttle such that the transport element is formed as an advance clamp which grasps the separated nail strip laterally during the forward movement of the transport shuttle in such a way that the nail strip resting against the stop surface can be clamped between the transport shuttle and the advance clamp by means of spring action, and can therefore be moved forwardly along with the transport shuttle.
