1299660 Jointing by rolling; making composite sheets ALLEGHENY LUDLUM INDUSTRIES Inc 29 Dec 1970 [2 Jan 1970] 61688/70 Headings B3A and B3M Apparatus for roll-bonding between rolls 40 and 50, Fig. 1, a number of thin parallel strips fed from a coil 2, to a substrate fed from a coil 1, includes guiding rolls 10 which prevent misalignment of the strips relative to the substrate. The rolls are arranged to move axially in response to lateral movements of the substrate. The strips are hot or cold-bonded to the substrate, and the substrate may be slit longitudinally to produce lengths of substrate having a thin strip along each edge. The substrate may be of stainless steel, and the strips (in the form of wire or foil) of aluminium, zinc, cadmium, magnesium, or a base alloy of such a metal. The final product may be used as a trim strip for a car, with the thin strips along the edges acting as a sacrificial metal. As shown in plan in Fig. 2, the guiding rolls 10<SP>1</SP> are provided with grooves for the strips, and are carried between side frames 16. The substrate runs between rollers 20 which are coupled to the frames by supports 26 and a screw 24. If the substrate shifts laterally, the rollers 20 follow the substrate and cause the frames 16 and the rollers 10<SP>1</SP> to move correspondingly. The frames are slidably mounted on fixed rods 22 for this purpose. The screw 24 allows the spacing of the rollers 20 to be adjusted for different widths of substrate. |
