ABSTRACT:
A parts supplying apparatus for carrying and supplying a part such as a projection nut to a predetermined point in space comprises a telescopic supply rod including an outer and inner shaft, and a magnet being fixed to a proximal end of one of the two shafts. The supply rod first extends in its entirety towards the predetermined point, or destination, with the part attracted and held at the proximal end by way of the magnet. When the part reaches slightly short of its destination, relative displacement in longitudinal direction of the outer and inner shafts takes place so that the magnet is moved away from the part until its magnetic force on the part is no more influential, whereupon the part is allowed to fall under gravity down to the destination accurately.
