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.
