![]() This image shows clearly the
two (yellow) hydraulic cylinders, used to set pressure to
the top roller. These cylinders are interconnected to
guarantee an even pressure on both sides of the press. The
maximum force these cylinders can produce is 10.000 kgs.
(22.000 lbs.) each. The total maximum downward force of the
top roller is therefore 20.000 kgs. (44.000 lbs.)These
cylinders are not intented as a tool to move the top roller
vertically when this roller is not under pressure. The
"normal" pressure spindles will take care of that. The top
roller rests on heavy pressure springs. This means that the
top roller will follow the movement of the pressure
spindles, both up and downwards.The pressure in the
hydraulic system, which indicates the downward force of the
top roller, can be read on a gauge. This allows to use the
same pressure in a future printing run easily. Use the "back-button" to go back to the JZM pages. |
