ABSTRACT:
Apparatus for inserting longitudinal studs in a concrete road covering. By means of a longitudinally running sled and forks, an exact parallel orientation of the longitudinal studs is achieved, as well as their arrangement at a predetermined height. Through the automatic loading of a holder for the longitudinal studs and the synchronization of the device with the motion of the device for inserting cross-studs, a minimum distance between the longitudinal ends and the cross-joints is maintained.
