Abstract
For the initial operation or changeover of a can body welding machine, a modular stack magazine to guide and hold a stack of blanks has adjustable stack supports with holding surfaces projecting under the lowermost blank. These stack supports are adjustably mounted on a frame which is releasably connected to a blank separating device. To assist the destacking of individual blanks, adjustable spreading air feed elements are also fitted to the frame. These adjustable components together with the frame form an exchangeable module, so that once their settings have been carried out--the setting operations being inherently complex, because as they are governed by many other parameters besides size of blank they have to be arrived at empirically, and they must be made all over again if just one of those parameters is altered--the module can be stored ready for reuse after maintenance operations, or after the use of another module.
