For effective safeguarding of the main nip between the rolls there should be a sensitive trip bar, known as a Lunn bar, fitted parallel to the mill rolls and positioned so that the operator works over it. The Lunn bar has proved effective in reducing the number of fata l and serious maiming injuries at two roll mills from their historical level of...operating a 3 roll bending machine. In particular: The use of gloves with fingertips during initial feeding of work pieces should be prohibited because the tips can be caught and drawn into the roll intake. Where there is a genuine need for hand protection, palm protection only may be sufficient. Loose fitting clothing should not be worn.

The cutting tool is rigidly held and …...forces by actually decreasing web tension as the roll builds. The amount of taper tension is normally measured in percentage of set tension. For example, using the same 3.5 inch core diameter and 35 inch outside roll diameter, if taper tension was set to 50%, the tension will be linearly decreased from 3.5 inch core to 35 inch roll diameter so the
What is the Principle of three roll mill? The three roll mill has 6 main parts, such as roller, bearing, motor, heating dealing, cast parts and painting. The motor drives cast gears, to move 6 pcs of bearings of rollers. The cooling system controls the water of each roller, temperature is cannot be belittled.
