PURPOSE: To make it possible to manufacture an economical shutter without using any holding type at all with a manufacturing means which attaches a greater importance to a shutter function and interconnect shutter members of an opening and closing type rolling up shutter without shaking and manufacture a sound absorbing shutter capable of minimizing noise, such a wind pressure noise or operating noise effectively.

CONSTITUTION: A shutter raw material 3 supplied continuously from a raw material supply device 2 which supports a coil 1, which winds up the shutter formation raw material 3 is consecutively cut in specified sizes equivalent to the width of a finished shutter by means of a notching/cutting device 4. After it is cut, the raw material is passed through a roll forming device 5, thereby forming connection edges on both edges of the shutter raw material 3 consecutively. Then, the material is drawn out and placed on a take-out mount 6.
