However, in the above-mentioned method, what is folded along the perforation 5 is sent to the margin slitter by the pin tractor b, but the continuous form is folded in two or only a part is folded. In the case of folding, there is a problem that smooth feeding cannot be performed because the margin in which the pin hole is formed does not come on both sides of the folded form. Therefore, as shown in FIG. 11, a postcard is formed using a continuous form in which only perforations 4 extending in the width direction are formed, and no perforations are formed in the feed direction (perforations may be formed in the feed direction). A device for creating the has been proposed. FIG. 12 shows the same apparatus. A continuous form is cut and separated by a burster f at a perforation position in the feed direction of the continuous form, and is sent to a belt conveyor g as a cut sheet.
