    Hi All,

    The delivery chains on our DI are due for replacement. I have purchased a set of chains from Heidelberg and would like to know how to replace them.

    Does anyone have a practical/easy method of doing this - please advise.

    What should I be careful of when doing this so as not to cause any problems / damage to the press?

    Many Thanks

    Hi sir:
    Carefully :
    1) In order to maintain
    the pretension and at the same time not to overstress
    the torsion springs ,had been modified gripper
    bars, i.e. they were equipped with an additional
    torsion spring.
    2) Removal and installation of gripper bars
    3) Checking/adjusting the gripper bite
    4) Checking/adjusting the gripper closing times .
