摘要

A solvent is metered onto the upper portion of a cylindrical surface while said surface moves at a rapid rate of speed due to its rotation about an axis. The solvent is uniformly distributed along the extent of said surface in all directions to form a continuous film of desired thickness for loosening foreign material carried by said surface. The solvent film is maintained on the moving surface through a segmental arc and is then separated from said surface together with the then loosened foreign material.
