Internally lubricated felt, brush or cellpor rolls apply the forming medium to the coil or blanks. Suitable for different material widths and thicknesses. Throttle valves facilitate setting different quantities of oil for the top and bottom side. With the sector lubrication systems, total or partial lubricant application is possible. Blank lubricators can be used as mobile table trolley structures for multiple operational use. The integrated open-loop control electronics and pressure reservoirs allow the lubricating rolls of the PBA to apply a defined layer of lubricant on round plates and blanks.
