Abstract: A method and device for honing a metal strip of arbitrary width in continuous motion, allow honing of a suspended portion of at least one side of a metal strip, being free of artifacts and automated. The device includes a device for vertically positioning an abrasive element at the surface of the strip. A device for horizontally moving the abrasive element transversely to the motion of the strip can be coupled to the vertical-positioning device and moved back and forth from one edge of the strip to the other. A first device allows uniform pressure to be applied to press the abrasive element against the strip. The first device allows a uniform pressure to be applied to a suspended portion of the strip in motion and can be coupled to a second device allowing the pressure to be adjusted according to the longitudinal tension of the suspended portion of strip.

Abstract: A splicing machine for connecting metallic bands including at least three toolings determining successively the cutting profile of both edges (m1, m2) to be connected, the welding of both edges on to one another and the flattening of the welded matter in excess. The machine includes a tool carriage (3) mounted to slide parallel to the running direction of the bands (M1, M2) on which are mounted to slide, perpendicular to the running direction, at least two supporting chassis (41, 51), each for one of the connecting toolings (4,5), a motor and a worm (32) for positioning either connecting tooling (4,5) in a common working position, by sliding the tool carriage (3) and apparatus to control the transversal sliding motion of the corresponding tooling for the actuation of the latter.
