Folding Device and Printing System

A folding device for folding continuous paper, which is previously provided with fold lines at given intervals, along the fold lines in a zigzag pattern, the folding device comprising:

• a feeding member of the continuous paper;
• a swinger fin that swings using one end thereof as a fulcrum like a pendulum in synchronization with the fold lines while feeding the continuous paper into the inside thereof;
• and
• a table to be surmounted by the continuous paper that has been folded, wherein:
• the swinger fin is driven by a pulse motor and controlled in swing velocity step by step;
• the number of drive pulses of the pulse motor in each step is determined according to top-and-bottom length of the continuous paper;
• and maximum swing velocity of the swinger fin and pulse frequency in each step are determined according to feed rate of the continuous paper.

• and
• a table to be surmounted by the continuous paper that has been folded, which are arranged in the order named as viewed in a feeding direction of the continuous paper, wherein:
• a travel sensor for detecting a traveling condition of the continuous paper is disposed between the feeding member and the swinger fin, as viewed in the feeding direction of the continuous paper.

• a feeding member of the continuous paper;
• a swinger fin that swings using one end thereof as a fulcrum like a pendulum in synchronization with the fold lines while feeding the continuous paper into the inside thereof;
• a paddle member for pressing a fold line portion of the continuous paper fed to the swinger fin;
• a table to be surmounted by the continuous paper that has been folded;
• and
• top-and-bottom length setting means arranged for setting top-and-bottom length of the continuous paper, wherein:
• the paddle member includes:
• a pair of paddle units in which distance therebetween is variable so as to correspond to the top-and-bottom length of the continuous paper;
• and
• a distance-detecting member for detecting the distance between the paddle units.
