Abstract:
A pin action timing adjustment device for a folding cylinder, comprising:a folding cylinder,plural pin mechanisms which cause pins provided in said folding cylinder to rise and set on the outer circumferential surface of said folding cylinder,plural folding blade mechanisms which cause folding blades to rise and set on the outer circumferential surface of said folding cylinder in conjunction with the rising and setting of said pins provided in said folding cylinder,a pin action fixed cam having the same center as the rotation center of said folding cylinder,a folding blade action fixed cam having the same center as the rotation center of said folding cylinder,a pin action rotating cam and folding blade action rotating cam formed in one piece having the same rotation center as the rotation center of the folding cylinder, which can selectively change over between a state wherein the cams rotate in a predetermined relation to the rotation of the folding cylinder and a state wherein they have stopped in a predetermined relation to said pin action fixed cam and folding blade action fixed cam,a pin cam follower provided in said pin mechanisms which causes said pins to rise and set from the outer circumferential surface of the folding cylinder together with the pin action fixed cam and pin action rotating cam,a folding blade cam follower provided in said folding blade mechanisms which causes said folding blades to rise and set from the outer circumferential surface of the folding cylinder together with the folding blade action fixed cam and folding blade action rotating cam,a control mechanism linked to the pin action fixed cam which causes the pin action fixed cam to undergo an angular displacement around its center, anda stop mechanism connectable to the pin action fixed cam, and which stops the pin action fixed cam with a phase whereby it was displaced by said control mechanism.
