  • Patent number: 4403723
    Abstract: Under direction of a machine controller, an endless chain conveyor is incrementally passed by a plurality of loader heads. The loader heads receive a series of components taped on a reel supplied substrate, sever individual taped components from the supply, and load the individual taped components onto clip carriers of the endless conveyor, on command, in a preferred sequence. The clip carrier mounted components are then indexed past a cutter assembly for trimming the lengths of the leads and removing the substrate, and a positioning disc assembly for positioning the components in the clip carriers before being passed to a rotary transfer assembly. The rotary transfer assembly removes individual components from the conveyor and rotates to an unload position above a linear loader, which laterally transfers the components from the rotary transfer to an insert head assembly.
    Type: Grant
    Filed: April 18, 1980
    Date of Patent: September 13, 1983

  • Patent number: 4029131
    Abstract: An apparatus for sequentially feeding non-axial lead electrical components in their manufacturing strips from a magazine to a forming station where they are removed, bent into a substantially axial lead configuration and taped between two pairs of continuous ribbons of tape. The leads are straightened while in the manufacturing strip by being placed under tension.
