Instructions for Regularly-Wound Tape:
We sometimes get calls from customers saying they may have a defective roll of double-sided tape since the release liner on their roll of tape is reversed and now the tape is on the top of the liner. The answer is that that effect will happen when the liner on a double-sided tape roll is removed from a roll without the tape coming off at the same time (if the tape was on the outside of the roll then it would have stuck to the lathe when it was originally cut or to the box it was shipped in for that matter). When the liner goes one revolution around the roll without tape coming off at the same time it will then seem like the roll is reverse wound. To correct the problem you just need to unwind the tape alone (make sure the liner stays in place while you are unwinding the tape) from the roll and go one full revolution around. Then just cut off the tape after that one revolution and the tape will now seem like it is wound the correct way again.
Instructions for ATG (Reverse Wound) Tape:
We sometimes get calls from customers saying their roll of ATG tape is wound backwards (either at the beginning of the roll or somewhere in the middle of the roll). That effect will happen when the initial leader on an ATG roll (the piece at the beginning of the roll which prevents the adhesive from sticking to the packaging the rolls are sent in) is aggressive so you have to be careful it doesn't take off the first layer of adhesive when it is removed from the roll. Also if the adhesive on an ATG roll sticks to a surface without the liner being wound up at the same you can see that effect. Basically when all the adhesive comes off one full revolution of a roll without the liner being wound up at the same time it will then seem like the roll is wound like a regular roll of double-sided tape instead of a reverse-wound ATG roll. Before you start the procedure below it sometimes helps if you use your finger to press firmly down on the width of the tape as you go one revolution around the roll which will help transfer the adhesive to the correct side. Then to correct the problem you just need to unwind the liner alone (make sure the adhesive stays in place while you are unwinding the liner) from the roll and go one revolution around. Then just cut off the liner after that one revolution and the tape will then seem like it is wound the correct way again.
