Sometimes the mills cutting the steel have dull cutting tools. What happens then is the sheet on top has a slight burr along the cutting edge that curls down and hooks unto the sheet on the bottom. This is a very small burr, but you can feel it with your hand and see it if you look reeeeeally...
A steel brush only helps if sheets are precisely stacked one on top of the other. We did have a steel brush on one of our machines, it made so little difference that we didn't see much of an advantage over not have one at all.
The peeler can lift the sheets no problem, as a matter of fact the peeler will lift all of the sheets of the pallets in the corner if they are stuck together. So it's plenty strong, it's just not a good way of separating sheets reliably. Like I said a peeler and air blowing is not reliably...
We use steel straps that have been chopped into 2" pieces. They get hammered in between every sheet.
This is a fool proof way of getting it to work, but it takes time and I would imagine there should be a machine out there that can separate this kind of material already. Let me know what you think.
Anyone know of a sure way or separating sheets of thin non-magnetic material consistently? Or a machine that can do that. We run through our laser 5 to 6 pallets a day of 20, 18 or 16ga SS. The sheet separator on the loading machine has the conventional pumping actin of the a vacuum cup and air...
