Apparatus for simultaneously deforming and coating

An apparatus for applying a sealant to the inside surface of opening portions of a can end having a curled portion for seaming in order to reinforce it and to prevent leakage of the contents of the can, said apparatus comprising a vertically movable plunger having a top, a stamping die fitted to said plunger top, said stamping die being movable between a lower position and an elevated sealant applying position, a frame defining a chamber surrounding said plunger for accommodating sealant and a cover for said chamber, an inlet port for sealant provided in a side surface of said frame, a central hole provided in each of said frame and said cover so as to permit the vertical movement of the stamping die therethrough, the relative dimensions of said central holes and said stamping die providing a narrow clearance between the stamping die and the central holes thereby removing excess sealant adhering to the periphery of the stamping die, said frame having an inside wall defining said central hole in said frame and a slit formed in the inside wall of the frame below the cover and above said stamping die lower position so as to surround the stamping die for extruding the sealant therethrough toward the upper surface of the periphery of the stamping die at the predetermined lower position of the stamping die.
