In a method for the production of toaster heating elements firstly connecting strips made of electrically conductive material are arranged in the region of edge recesses at opposite edges at the rear side of a support plate, opposite to the heating side. Then a plurality of heating conductor wires are provided substantially parallel to one another and in such a way that they cross the connecting strips in the region of the edge recesses at the heating side and thereby are electrically connected to said strips. Furtheron the wires are cut off. In an apparatus for performing the method there is provided a processing station comprising a supporting surface for the support plate of the heating elements. The processing station further comprises housing grooves one for each connecting strips. Said grooves are situated at opposite side edge regions of the supporting surface. Further a delivery station associated with the processing station is provided. The delivery station comprises a plurality of supply reels for the heating conductor wires to be arranged on the support plate. A connecting device forms an electrically conductive connection between the heating conductor wires and the connecting strips. A severing device cuts for the heating conductor wires.
Method for the production of a toaster heating element comprising a heating conductor wire and a support plate provided with edge recesses at opposite edges, the heating conductor wire being disposed substantially over a front, heating side of the support plate, comprising the steps of arranging connecting strips of electrically conductive material at a rear side of the support plate (1), which is opposite the heating side, so that each strip extends fully across a dimension of the support plate in the region of the edge recesses (3) of a respective one of said opposite edges, arranging a plurality of heating conductor wires (2) substantially parallel to one another each of the conductor wires crossing the connecting strips (5) in the region of an oppositely located pair of the edge recesses (3) at the heating side, electrically connecting said conductor wires to the connecting strips (5), and then cutting said conducting wires to form discrete conductive lengths.
