FIELD: plastic metal working.
SUBSTANCE: apparatus for corrugating sheet material includes shaping members rigidly mounted on shafts. Shafts are rotated in opposite directions by means of their drive units. On one shaft shaping members are arranged normally relative to axis of shaft; on other shaft shaping members are arranged symmetrically relative to said normally arranged member and in pairs at mutual inclination angle α in range 15° < α < 90°.
EFFECT: possibility for making constructional members of panels with noise absorption properties.
