May I ask a question about how wide Pile reversal
was. You said 6 inches to 2 foot and then you say 6 inches to 1 foot I just do not under stand Which one it is.
I do know if it is 1 foot wide and a melt seam tray is 1 foot wide it can cause Pile reversal to happen. I think its an installer problem not the carpet manufactured problem.
This is just my option

6" to 12" along the edge.
Pile reversal is a defect.
Pile reversal can be any width along the edge.
not sure how it happens.

Your right it is a Pile reversal defect. How did it happen?
(a)Manufacture?
(b)Carpet Installer?
(c )Carpet Cleaner?
Who's the bad guy hint?
This seam is over heated but not as bad as the one picture Roger has showed. There are some things that resemble each anther like dip in the seam they both have one. The both have humps one has bigger hump than the other. The darker line the size of a seaming iron is were the installer started getting control of his seam iron. That same darker line is condense that has went up in to the fibers and now trapped by scotch guard and seam tape. The fibers could have change direction when the installer used a still tray and this held heat in the fibers to long. This just my theory. I hope this helps.

Pile reversal at the edges is may be serviceable by steaming, but it does not always work.
I have forgotten how it happens at the plant but it is often overlooked.
If the installers are having trouble producing a good seam, try the paper/pencil pile direction tests to see which direction the nap is pointing.
Once you see it and understand it, you will be able to see it from then on.

I get a kick out of you Darian..
You know which way to make the seam.
If you go the opposite way, you train the nap to go the opposite direction from manufactured direction. Both sides of the seam are affected, not one side.
Pile reversal finds one side of the seam affected, not both sides and the pile is in two different directions.
If you run the iron into the nap, rather than with the nap, the paper/pencil test will find a change of direction at the seam edges only, not 12" into the panel.

Pile reversal finds on one side of the seam affected ok then so it is manufacture fault right.
Thanks Ray I'm writing a note so I don't forget.

Pile Reversal is the mills problem if it was caused by the installer seaming it would have been on both sides of the seam.
Know who's fault for the over heated seam? I agree soft bac will shrink and curl in but Shaw has taught installers for years that they needed to turn their iron up on high to make sure they get the glue runny enough to get thru the fleace. Now they have had this typ of prblems and have change their teaching but installers that had gone thru their training back then still think that is how it is to be done.

Roland do you look at the pictures or do you just give out answers.

The only picture's I could see was the very first one's. If there is more they are not coming thru for me to see. But I still stand on the part that Shaw was training installers to turn their irons up on soft bac

Roland your right about Shaw iron temp. The first two pictures look hard and you will see a darker line that is the seam. Now while your focusing on the darker line look closer at fibers you will see a void there and that void is the seam line right in the middle of the darker area.
That what i see.
