Abstract:
1. A device for folding a continuous paper having perforations, the device comprising: a swing arm pivotable about an axis at one end of the swing arm to guide the continuous paper to be accordion-folded along the perforations with equal widths as a result of a swinging operation of the swing arm, and a table that receives the folded continuous paper fed via the swing arm, wherein the swing arm includes a telescopic structure varying the length of the swing arm to at least two different lengths in a swing, wherein the swing arm comprises an arm main body, a sub-arm disposed on a free end of said arm main body, and a telescoping operation motor which extends and retracts said sub-arm from the tip of said arm main body, wherein said swing arm is pivoted about said axis by a swing operation motor disposed in said axis, wherein said sub-arm has a pair of plate members that both project from the tip of said arm main body when the swing arm swings to either side, and wherein said sub-arm maintains a pre-determined distance between a lowest portion of said sub-arm and an upper surface of said continuous paper placed on the table, thereby reducing a size of a part of the continuous paper which is subjected to a wind-pressure.
