ABSTRACT:
Assembly apparatus for a wear resistant plastic mining screen, preferably one made out of wires formed by extruding urethane around a rigid steel core, includes a feed roll having spaced grooves for receiving elongated profile wires which define the working surface of the screen. A support rod positioning member is mounted at a welding station to frictionally receive a screen support rod on its top side and then be flipped over to position the support rod above the profile wires which pass transversely under it. A welding bar having heated fin portions on its upper and lower sides is then passed between and in contact with the support rod and the profile wires to slightly melt them. The welding bar is then quickly removed and the support rod is quickly moved downwardly against the profile wires and held until the integral joints formed at each intersection are solidified. Additional support rods are welded to the profile wires at spaced intervals until the desired screen length has been reached.
