<p>A method of pressure-welding a composite material includes passing a pair of strips (1, 2, 11, 12) through a gap (g) between a pair of pressure-welding rolls (5, 6, or 15, 16). One or both of a composite material (7, 17) pressure-welded by passing through the gap and one of the strips introduced into the gap are wound around one of the pressure-welding rolls. Under this state, the pair of pressure-welding rolls are made to have different peripheral speeds from each other, thereby controlling the draft of each strip. </p> |
