Abstract
Band shaped contact material is advanced along an approximately horizontal contact material guide past a displaceable knife and counter-holder which cooperates with a stationary counter-knife to a directly adjacent approximtely horizontal contact piece guide in alignment with the contact material guide for receiving successive contact pieces cut-off by the knives which are ejected from the contact piece guide by horizontal advance of the contact material onto a horizontal surface of a vertically movable electrode of a resistance welding device which raises the contact piece into compressive contact against a contact carrier held on the surface of a stationary upper electrode of the welding device and then the two pieces are welded together. Interconnecting apparatus is operative to simultaneously draw back the contact material after the ejection step into the position necessary for the knives to cut off the next contact piece as the previous contact piece is welded to a contact carrier.
