Carpet shearing is a process that trims and levels carpets to create a variety of effects, including:
Creating a pattern: Tip shearing is a technique that involves tufting some carpet loops higher than others, then shearing the carpet to cut the taller loops but not the shorter ones. This creates a pattern with a darker cut pile that looks like a shadow.
Leveling: Shearing can be used to level the carpet after washing, trimming off any protruding tufts and fuzz.
Revealing pattern: Shearing can reveal the pattern of a hand-knotted rug.
Making imperfections less noticeable: Shearing can make minor weaving imperfections less obvious.
Aging: Shearing can give a new rug an aged look.
Thinning: Shearing can transform a thick pile rug into a thinner one.
Even out wear: Shearing can even out the appearance of rug wear.
Carpet shearing is usually done after the backing process as part of the in-line process
