ABSTRACT:
A flexible belt carrier is provided for use in an apparatus for spray soldering the ends of roll capacitor blanks. The belt may be constructed of silicon rubber and has apertures extending transversely through the belt which are positioned very near to one of its surfaces. A slit or opening is made at each aperture through the web separating the aperture from the nearest surface of the belt. The belt moves in a sinuous path such that when flexed around a pulley in one direction the edges of the slit spread and gap, allowing ready insertion of a blank. When the belt passes over another pulley, the belt flexes in the opposite direction so as to foreshorten the slit surface. The slits are made at an angle acute to the surface of the belt. Therefore, as their surface foreshortens, the walls of the web formed at the slit cam against one another and overlap, thereby fully and tightly encircling the capacitor blank, exposing only the ends thereof. At this point, molten solder is sprayed at the sides of the belt and makes contact with the ends of the capacitor blank, adhering thereto. The belt then passes around another pulley which causes the slit edges again to gap, freeing the capacitor blank which is then ejected from the belt. The flexing of the belt loosens any surplus solder that may adhere to the belt.
