1. Steel strip arrives at the can manufacturing plant in large coils.
金属板材以大卷的形式运到制罐厂
2. Steel strip is cut into large sheets
卷材被切成大的片材
3. Lacquer is applied to the side of the sheets that will become the internal surfaces of the finished cans. This special lacquer is to protect the can itself from corrosion and from any possibility of interaction between the contents and the metal.
在将成为罐体内表面的一面涂漆，涂漆是为了防止金属本身锈蚀或与内容物发生反应
4. The lacquered sheets are dried in an oven.
漆膜经过烘道干燥
5. The large sheets are slit into small sheets, one for each can body.
片材被分成小块，每一小块做一个罐身
6. Each small sheet is rolled into a cylinder.
每个小片被卷成一个圆筒
7. The cylinder edges are welded by squeezing them together whilst passing an electric current through them. This heats up the metal sufficiently for a sound joint to be made.
卷筒的二边挤压在一起通过电流，这会加热金属表面并把二边金属牢牢地焊接在一起
8. The inside surface of the weld is sprayed with lacquer and then cured by blowing heated air on to the outside of the cans.
罐内壁进行喷涂并在罐外吹热风使之干燥
9. The cans are passed through a flanger where the top and bottom of the can are flanged outwards to accept the ends.
罐身通过一个刮板使罐顶和底部形成折边以便与罐底结合
10. Plain ends are seamed to the can bodies to close one end of every can.
每个罐身都与一个罐底卷合
11. The cans are passed through a beader where the walls of the cans have circumferential beads formed in them to give added strength.
罐子通过一个滚边机给罐身滚筋以增加罐身强度
12. Every can is tested at each stage of manufacture.
At the final stage they pass through a pressure tester, which automatically rejects any cans with pinholes or fractures
每个生产环节都对罐子进行检测。最后罐子通过一个压力检测机，并自动剔除有针孔或爆裂的罐子
13. The finished can bodies are then transferred to the warehouse to be automatically palletised before despatch to the filling plant.
成品罐体运往仓库并自动码垛等待运往灌装厂
