Particularly rugged & and long-lasting The ROTOL squeeze-on roller system is a lubricator developed exclusively in house by Eckardt. This is an exceptionally rugged, long- lasting lubricating machine designed to apply lubricant in precisely defined film thicknesses over an entire surface. Features & benefits • Far longer service life in comparison with conventional felt rollers • Works with all pumpable lubricants • Achieves thinnest, homogeneous film thicknesses • Very high viscosities possible • Rugged ROTOL calender roller made of non woven material • Practically impervious to mechanical damage • Lubrication media is retained on the surface of the roller; no premature wear resulting from being drawn in How it works Fleece rollers remove cleaning liquid, for example, from cleaned metal parts during the forming process of carbody parts. Following close consideration we came to the conclusion that this principle of “squeezing off” could be reversed and used to apply lubricants. That is the basis for the ROTOL squeeze-on lubricator. The fluid medium is fed between the distributor roller and the fleece rollers. (the amount of oil fed into the system is not decisive). The medium spreads across the entire width of the roller. The fluid is absorbed by the open pores of the fleece roller. The line pressure acting on the pores increases constantly as the roller rotates on the surface of the sheet metal; the roller begins to flatten. The fluid forms a wedge between the fleece and the surface of the sheet metal. Depending on the pressure the porosity of the fleece roller reaches practically zero. The media is squeezed onto the surface absolutely homogeneously.
