Zusammenfassung:	The invention relates to a bending machine for forming a corrugation (2) in a metal sheet (1). The metal sheet (1) is used for constructing a sealing film of a fluid storage tank. The bending machine(9) includes a lower frame (11), a lower mold with a print, an upper frame (10) including an upper punch. The bending machine (9) also includes a first and a second pointer (35, 36) mounted on two sides of the upper punch (12). Each of the first and the second pointer (35, 36) includes a lower end facing the lower end of the lower frame (11). The first and the second pointer (35, 36) are mounted on the upper frame (10) in a manner of rotating between a static position and a working position around a rotary axis parallel to a longitudinal axis of to-be-formed corrugation.
