Newspaper production apparatus

A newspaper production apparatus, comprising:

• a paper feeding unit which feeds a continuous paper;
• an ink jet printing unit;
• a folding unit which cuts and folds the continuous paper having been printed;
• and
• a controller which controls the folding unit,
• wherein the folding unit is a rotary folding unit provided with a folding cylinder including:
• a retaining mechanism which is capable of retaining a sheet on an outer circumferential surface of the folding cylinder and is capable of releasing the retained sheet at an appropriate timing by control of the controller;
• and a folding blade mechanism which projects the retained sheet radially outward at an appropriate timing by control of the controller, and
• the rotary folding unit is controlled by the controller to, by performing an operation of releasing the retained sheet by the retaining mechanism and an operation of projecting the retained sheet by the folding blade mechanism once in an arbitrary plural number of turns of the folding cylinder, be capable of collect run by which sheets retained by the retaining mechanism are folded at each arbitrary plural number of turns of the folding cylinder.
