ABSTRACT:
An apparatus for solder joining metal tapes to form laminated metal tapes comprises a channel means having a base, and sidewall means extending therefrom to a cover extending over the sidewall means. The sidewall means define converging channels having an entrance end for admitting the tapes spaced apart, and an exit end where facing tape surfaces can come into contact. The sidewall means separate the base and cover by a distance selected to align the tapes in the width dimension. The cover having a first section extending from the exit end, and a second section extending from the first section to the entrance end, the second section being formed with a cavity facing the channel that permits a solder flow therethrough that minimizes accumulation of particles in the channels. A solder duct means mounted on the channel means for directing molten solder into the channels to flow from the exit end to the entrance end. The solder duct means having a slot extending therethrough and aligned with the exit end. A seal means mounted on the solder duct means adjacent the slot for minimizing solder escaping from the slot while solder coated tapes pass therefrom, and a wiper means mounted on the solder duct means and positioned from the seal means removes exess solder from tapes passing through the seal means.
