An apparatus which is suitable for automatic operation is provided for riveting bowed leaf-like springs to flexible bodies, e.g. for riveting shanks to innersoles. Two riveting devices are included in the apparatus for simultaneously riveting the two ends of the shank to the flexible body. This means for feeding the flexible body to riveting position and the means for feeding rivets to the riveting devices are more or less conventional. The shanks to be united to innersoles are fed one at a time, from a pair of magazines holding a stack of shanks at the ends, to a pair of guide bars containing matching grooves, pushed along the grooves by a pusher means, which shanks at the end of the grooves arrive at the riveting position. At the end of the grooves, the lower ends of the latter are in the form of leaf springs so that the shank to be united can be snapped out of the groove. The guide bars are mounted so as to be pivoted downwardly against the action of a spring. As the riveting devices press against the shank and flexible part to be united, these parts are firmly retained in their proper position as the shank is snapped out of the groove and the riveting action is finished. |
