It is a standard fact that the perf tool on your folding machine isn’t that great. It is something that is accepted and battled with, and it feels like you must make the best of a bad situation. But when push truly comes to shove, you are forced to outsource that special job that needs a fine flat perf. So why doesn’t it work, and why do we stand for it?
Why doesn’t the perf tool work?
Does the image below look familiar? I bet if your folding machine came with a perf tool it does. Standard blades are generally not made to last (hence the missing tooth), not only that but they tend to be around 12tpi (teeth per inch). In general, this number needs to be higher, especially if you are working with thinner stocks. Standard flatbed perf blades tend to start at 17tpi and the rule of thumb is that the thinner the stock, the higher the tpi.
So we have took a brief look at the blade, but what about the boss? Again the picture below will be all too familiar to a lot of machine owners and operators. The boss, just like the blade, wasn’t created for such intricate applications and has no longevity (in other words, the more you use it the poorer results you will achieve). This already has alarm bells ringing, metal on metal will never end well, especially with a cheap perf blade. There is only so long that two bits of metal can repeatedly hit into each other before something wears away, and in this scenario the blade’s teeth will be the first thing to go.
These two poor components result in a perf that viciously punches the paper, leaving the finished job with a ridge along the perf line and covered in paper dust.
Why do we accept this method?
Sadly there is no definitive answer to this question. Unfortunately the industry has accepted that the tools they are able to acquire are not fully up to the task, so when a job comes in that demands a high quality finish it is immediately outsourced. When something is done a certain way people generally accept that as normal. Rotary perforating has a stigma attached to it which until recently it hasn’t been able to shake.
The perf revolution begins
The reasons given above for the acceptance of less than adequate micro- perforating, while true, are not acceptable, and that is where Tech-ni-Fold comes in. We wanted to solve this issue rather than accepting it and our Micro-Perforation Tool uses some of the best engineering techniques we could source to produce blades that maintain their quality throughout millions of sheets, and we have also stepped away from the metal boss to run our blade along a nylon sleeve to keep the perf flat and neat.
