Lamination lubricant dispensing unit for lubricating a working roller of a rolling mill for laminating a sheet of alkali metal or alloy thereof into a film

A rolling mill for laminating a sheet of alkali metal or alloy thereof into a film, the rolling mill comprising:

• a frame;
• a first working roller rotationally mounted to the frame, the first working roller having a first lamination surface;
• a second working roller rotationally mounted to the frame, the second working roller being disposed below the first working roller, the second working roller having a second lamination surface, the first and second working rollers being positioned to receive the sheet therebetween;
• a lamination lubricant dispensing unit for supplying lubricant onto the second lamination surface, the lamination lubricant dispensing unit comprising:
• a dispensing unit body defining a laterally extending wall;
• first and second side walls extending forwardly from the laterally extending wall;
• and
• a ledge connected to a lower end of the laterally extending wall and extending forwardly from the laterally extending wall, the ledge being connected to lower ends of the first and second side walls and extending between the first and second side walls, the ledge, the first and second side walls and the laterally extending wall defining a recess having an opened side, the ledge having a front edge abutting the second lamination surface, the ledge being an angled portion extending upward and rearward from the front edge toward the laterally extending wall, the dispensing unit body defining at least one lubricant passage having an outlet defined in the laterally extending wall;
• a lubricant reservoir for holding lamination lubricant therein;
• and
• a pump fluidly connected between the lubricant reservoir and the at least one lubricant passage for supplying lamination lubricant from the lubricant reservoir to the at least one lubricant passage, from the outlet of the at least one lubricant passage, lamination lubricant flowing along the ledge to the front edge of the ledge and from the front edge onto the second lamination surface.
