Patent ID: 7217233

Claim:
A parallel folding apparatus of a folding machine, comprising: a first cylinder and a second cylinder arranged, with circumferential surfaces of said first cylinder and said second cylinder being in contact with each other; a guide member for guiding a signature which is transported on a lower circumferential surface of said second cylinder after being parallel-folded by gripping/holding means of said second cylinder in cooperation with knives of said first cylinder, said guide member including, a stationary guide which is located downstream, in a rotating direction, of a point of contact between said first cylinder and said second cylinder and disposed along the circumferential surface of said first cylinder and the circumferential surface of said second cylinder, and a moving guide which is disposed in such a manner as to be movable by drive means in accordance with an operating speed of said folding machine between a close position, where said moving guide is moved to a position closer to the circumferential surface of said first cylinder and the circumferential surface of said second cylinder than said stationary guide inside an area defined by said first cylinder, said second cylinder and said stationary guide, and a remote position, where said moving guide is moved to a position as remote as, or outside said area and more remote than, said stationary guide, and wherein said first cylinder is a first jaw cylinder for forming a signature in cooperation with a folding cylinder, and said second cylinder is a second jaw cylinder for folding said signature in cooperation with said first jaw cylinder or for receiving said signature from said first jaw cylinder without folding said signature.
