Patent number: 7326161Abstract: A folder includes a cut-off cylinder, etc. for cutting a web into sheets; a group of cylinders for folding each sheet into a signature in accordance with the selected folding specifications; and a conveyer apparatus, a fan wheel, a delivery conveyer, etc. for conveying signatures. In the folder, a cutting blade, etc. are disposed on the upstream side of the cut-off cylinder with respect to the feed direction of the web. When the folding specifications of signatures are changed or when the width of the web is changed, a control device operates the cutting blade to cut the web, and controls the feed of the web in such a manner that only a cut portion of the web present on the downstream side of the cut blade with respect to the feed direction is conveyed to the delivery conveyer.Type: GrantFiled: April 28, 2005Date of Patent: February 5, 2008Assignee: Komori CorporationInventor: Akira Ishikawa

Patent number: 6779788Abstract: A web of printed paper is cut into sections by a cutting cylinder while riding on a folding cylinder, and each paper section has its midpart subsequently pushed by a folding blade on the folding cylinder into a jaw cavity formed in the surface of a jaw cylinder in order to be folded into the form of a signature while being transferred from the folding cylinder onto the jaw cylinder. Mounted adjacent the opposite ends of the jaw cavity in the jaw cylinder are a pair of hooks which are cammed into and out of the space that is created by the midpart of each paper section upon insertion in the jaw cavity. The paper section has its midpart positively retained in the jaw cavity while being folded. A set of fixed and movable jaws is also provided in the jaw cavity and functions mostly to fold the paper section rather than to grip the same against accidental detachment.Type: GrantFiled: May 29, 2003Date of Patent: August 24, 2004Assignee: Kabushiki Kaisha Tokyo Kikai SeisakushoInventors: Yukitoshi Takahashi, Hiroyuki Fujinuma

Patent number: 6257142Abstract: Several printing units are arranged in a row for printing on as many separate webs traveling in centerline alignment and in phase with one another. At least one preselected web, on issuing from one printing unit, is directed over an angled guide rod thereby to be turned 90 degrees out of phase with the other, unselected webs. Subsequently traveling over a triangular shaped former, the preselected web is folded along a centerline thereof, back into phase with the unselected webs. The preselected web, already formed, and the unselected ones, yet unfolded, are then all superposed one upon another, with the fold of the preselected web in register with the aligned centerline of the unselected webs. The superposed webs are then folded by another former along the aligned centerline of the unselected webs. Subsequently fed into a cutting and folding device, the webs are cut and folded transversely into individual multiple-page signatures each having one center spread in addition to the usual inmost center spread.Type: GrantFiled: December 6, 1999Date of Patent: July 10, 2001Assignee: Kabushiki Kaisha Tokyo Kikai SeisakushoInventor: Takayuki Baba
