Bernie MillerI remembered that when I was working with the people at the factory where I had the perforating done that the machine could punch any size of hole any where and in any position on a particular panel because it was all programmed in advance. It would punch all holes that were the same size at one go, then they would change the die, do the next size and so on. The panel, during each operation would be moving wildly about as it was positioned for each perforation.
