How cans are made
Cans for food, drinks and non-food products may be constructed out of either two or three pieces of metal.
The first cans ever produced were three-piece and they were developed in the middle of the 19th century. They consist of a cylindrical body rolled from a piece of flat metal with a longitudinal seam, usually formed by welding, with a top and bottom, each seamed on the ends of the body.
Three-piece cans may be manufactured in almost any practical combination of height, diameter and shape. This process is particularly suitable for making cans of different sizes as it is relatively simple to change the parameters of the can under production.
The Cazander Brothers mainly have machinery for three-piece cans in stock.
What is a bodyroller?
The body roller is used prior to a semi-automatic welding machine. Where automatic welding machines roll the blanks into round cylinders, semi-automatic welding machines do not. Here the blanks must first pass through the body roller to be rolled into round cylinders, after which the cylinders are welded.
Cazander Brothers regularly offer quality used Bertil Ohlsson body rollers from their extensive stock.
