ABSTRACT:
A surface-treating apparatus for can body blanks includes a cutter for cutting an original sheet into can body blank materials having a predetermined width and capable of being divided into plural can body blanks, a conveying path for conveying the can body blank materials, a material-feeding device for intermittently feeding the blank material to the conveying path, and a heater for heating the blank material. First and second film-feeding devices are provided for respectively feeding a printed biaxially-stretched polyester film and a plain polyester film to both sides of the blank material along its conveying direction. First and second press-bonding devices will respectively successively press-bond under heat both films to both sides of the blank material and coupling the blank materials into a continuous form while defining metal-exposed areas for welding parts at both side edges of both surfaces of the blank materials. A cooler for cooling the continuous sheet of the blank materials, a blank material-cutting device for cutting the continuous sheet in its width direction at the space area between adjacent print patterns on the biaxially-stretched polyester film into surface-treated blank materials, a driver for driving the surface-treated blank material out of the conveying path, and a divider for dividing the surface-treated blank material into individual can body blanks according to the print are also provided.
