A lot of times during the course of the project we are asked if there are specific machines already available for production that we can buy, perhaps as surplus. A brief answer to this is no, there aren't any, but there are a few types of paper and web handling machines that do perform many of the operations needed. We do not have any folding or creasing steps in the process, and that's intentional, but we do have adhesive steps, and the application of adhesives can be a messy business if not handled right.
Shown are some envelope making machines that produce ordinary envelopes that you might use to mail a letter or more likely, pay a bill with. The principle of the system is to take a roll of paper and cut, fold, gum and shape, which should be simple. But look at how complex these machines really are, with their many stages and sections devoted to certain operations.
The paper rolled out into a sheet is referred to as the web in the paper industry. Webs have coatings put on, get rolled and rerolled, cut and converted, laminated with other webs, and more. The world of paper and sheets is a vast one.
Polaroid did have some machines used for the production of the sheet film. For instance, the sleeve making machine which we have designed our own version, is an obvious example. You can see some of them in this video.
