The invention discloses a continuous roll cold bending forming method for stainless steel water stop strips, which is characterized in that: continuous roll cold bending forming is adopted to produce roll-bent deformation pass by pass continuously by using a roll; upper and lower roll opposite rolling forming is adopted in a deformation process; and a guide vertical roll and a lateral roll are adopted at the same time. The method has the advantages of high product consistency, stable quality, unlimited length, reasonable straight angle change and arrangement and long equipment service life.
