Abstract
An adjustable bearing arrangement is used for the remote controlled adjustment of an inking roller or a dampening roller with respect to a second, contacting roller. The journal of the roller to be adjusted is secured to an adjusting element. A pre-settable adjusting force is transferred from one roller to the other. In the adjustment position, the receiving element or elements are locked so that it is temporarily impossible for the now adjusted roller to move either in, or opposite to the direction of adjustment.
Claims15
A method for adjusting a position of a roller in a printing press including:
- providing a first roller movable along a positioning path;
- providing a second roller;
- moving said first roller along said positioning path:
- placing said first roller in contact with said second roller;
- using a positioning force and forcing said first roller against said second roller by moving said first roller along said positioning path in response to said positioning force;
- providing a detent;
- using said detent for limiting said movement of said first roller along said positioning path of said first roller;
- and
- engaging said detent with said first roller subsequently to forcing said first roller against said second roller using said positioning force.
A method for adjusting a roller in a printing press including:
- supporting said roller for movement in the printing press;
- providing an operating device for moving said roller;
- applying a first force on said roller using said operating device during positioning of said roller;
- applying a second force on said roller using said operating device during production of the printing press;
- providing a detent;
- and
- using said detent for limiting movement of said roller subsequently to applying said first force to said roller during said positioning of said roller.
A method for adjusting a roller of a printing press including:
- supporting said roller for movement in the printing press;
- providing an operating device for generating a positioning force for said roller;
- providing an adjustable detent for limiting said movement of said roller;
- providing a detent adjusting motor;
- using said motor for adjusting said detent;
- and
- providing said positioning force for said roller greater than a counter force applied by said detent because of said detent adjusting motor.
A method for adjusting a position of a roller in a printing press including:
- placing a first roller in contact with a second roller;
- using a positioning force and placing said first roller against said second roller;
- providing a detent;
- providing a machine frame;
- using said detent for limiting a positioning path of said first roller;
- providing a counter-bearing on said machine frame;
- engaging said detent with said counter-bearing;
- and
- performing a follow-up on said detent until said detent comes into contact with said counter-bearing.
A method for adjusting a roller in a printing press including:
- supporting said roller for movement in the printing press;
- providing a piezo-electric operating device for moving said roller;
- providing a detent;
- using said detent for limiting said movement of said roller;
- applying a first force on said roller using said piezo-electric operating device during production of the printing press;
- and
- applying a second force on said roller using said piezo-electric operating device during positioning of said roller.
A method for adjusting a roller in a printing press including:
- supporting said roller for movement in the printing press;
- providing an electrochemical operating device for moving said roller;
- providing a detent;
- using said detent for limiting said movement of said roller;
- applying a first force on said roller said electro-chemical operating device during production of the printing press;
- and
- applying a second force on said roller using electro-chemical operating device during positioning of said roller.
