PURPOSE:To reduce variance of depth of a groove of an inlay type clad band, by forming the groove by removing a dummy wire rod which is superposed on a base material and rolled, and executing the rerolling by fitting in a clad wire rod. CONSTITUTION:On a band 2 of an optional base material, a dummy wire rod 4 is superposed, and is cold-rolled by rolls 5, 5. In this case, in accordance with a shape of the groove, a sectional shape of the dummy wire rod 4 and its hardness are selected suitably. Subsequently, a clad material 3 is fitted into a groove 21 on the base material 2 formed by peeling off the dummy wire rod 4 from the base material 2. After that, a clad band 10 obtained by rolling by rolls 6, 6 and press-contacting the clad material 3 is subjected to diffusion annealing and finishing cold rolling as necessary, by which a desired inlay type clad band is obtained. |
