Carpet seam tape installation.
When the carpet is stretched it is pulled where the edges of the tape are attached to the carpet and the two pieces lift to create a peak.
Carpet tape does make it possible to install multiple pieces of carpeting side by side and if you follow directions for installing carpet seam tape seams should blend with the rest of the flooring.

If you are replacing a section of already installed carpet just pull it back far enough so that plenty of the undersides are exposed.
Seam peaking occurs when the seam is set and then stretching occurs as the installation process is completed.
