A jaw cylinder in a jaw folder is provided. A first base ( ) includes a stationary member ( ) in a jaw mechanism. A second base ( ) includes a swing member ( ) having a jaw portion accessible to the jaw portion of the stationary member ( ). A third base ( ) has end axes ( ) at both ends and is rotatably supported by the end axes ( ) on a pair of opposite frames (Fa, Fb). The first ( ) and second ( ) bases are rotatably located on the third base ( ) about the rotational centerline of the third base ( ) relative to the third base ( ). The first ( ), second ( ) and third ( ) bases synchronously rotate to move the swing member ( ) close to and apart from the stationary member ( ) to grip a print therebetween. A jaw clearance adjusting mechanism ( ) turns the first ( ) and second ( ) bases about the rotational centerline of the third base ( ) in opposite directions to adjust a gap between the jaw portions of the stationary ( ) and swing ( ) members in the jaw mechanism.

In a pin action timing adjustment device of a folding device wherein a change-over between straight run and collect run is performed in one operation for a folding blade action and a pin action, to make it very easy to adjust a timing with which pins fall relative to the projection of folding blades, to make a mechanism very simple, to largely reduce manufacturing costs, to effectively eliminate the occurrence of faults so that maintenance is easy, and to provide an adjusting mechanism which permits ample adjustment tolerance. A control means is connected to a pin action stop cam which causes the pin action stop cam to undergo an angular displacement around its center line, and a stop means which can be connected to the pin action stop cam which has undergone an angular displacement due to the control means and stops the pin action stop cam with a phase displaced by the control means.
