A method of splicing a trailing end of a downstream metal strip to the leading end of an upstream metal strip. The method has the steps of overlapping the leading end of the upstream strip with the trailing end of the downstream strip, and thereafter friction welding the overlapping ends together at a plurality of spots at which respective spot welds are thereby formed.

Method of and apparatus for splicing metal strips

A method and apparatus for the contactless determination of planarity and a ferromagnetic metal strip during transit of the strip through a strip-processing line or cold-rolling line. Hysteresis loops repetitively impressed in the metal strip and the tangential magnetic field strength is measured at a surface thereof and electromagnetic parameters are determined from the time course of the tangential field strength signal. The parameters are functions of the mechanical stress which is evaluated to determine residual intrinsic stress distribution and then the planarity or nonplanarity of the strip.

Method of and apparatus for contactless planarity measurements on ferromagnetic metal strip

Strip tension in metal strip subjected to a plastic deformation such as skin or dressing rolling, stretch bend leveling or stretching is adjusted by local variation of the temperature to establish a temperature profile which minimizes waviness and camber in metal strip.
