Peaks and Valleys
Actually, just peaks. Maybe we'll discuss valleys another time. Back in days of yore when super thick plushes and flowing shags were wall-to-wall favorites, you could trim the edges with a chain saw and still end up with an invisible seam. Those days are gone. Today short dense cut-piles and loops are popular and invisible seams are not always possible. Here's one reason why: When carpet is installed tension runs uniformly across the backing until it comes to a seam. Then the line of tension drops down through the seaming tape and up again and continues across the backing. This causes the seam to lift when stretched, resulting in a 'peak'. When we get a call regarding a 'side-match' issue, the vast majority of the time it's not a color variation but a shadow being cast on the 'downhill' side of the peak. This is why we recommend that seams run perpendicular to a strong light source whenever possible as well as the use of wide seaming tape, (which limits or eliminates peaking at the seams). One of our customers makes sure consumers are aware of that and has them sign a form confirming that peaking has been explained.
to check it out. Since consumers consume it infrequently, there are a lot of things about carpet they are totally unaware of. Accordingly, we think this is a great idea.
