Combers have been known which have at least one combing head comprising an oscillating nipper unit and in which an intermittently rotatable feed roller is mounted for advancing a lap feed to be combed in the combing head. The process eliminates short fibers, it achieves better parallelization of fibers, it straightens curls, and it removes neps and residue impurities. The combing process is normally used to produce smoother, finer . The feed roller helps to move forward the lap sheet by a small amount of 4.3 - 6.7 mm. The Role of Comber The comber is used in the production of medium, medium-fine and fine yarns, and enables a positive influence to be exerted primarily on the yarn Characteristics of: evenness, strength, cleanliness, and on the fabric characteristics of: smoothness, visual appearance, handle. In recent years, combing has been utilized for upgrading the quality of medium staple fibers. Blonde Buzz Cut with Blunt Bangs. A comber has a nipper head (3), detaching rolls (6), and half-lap (4), wherein, during a combing cycle, the nipper head (3) and the detaching rolls (6) are moved by a drive system (31 to 40) out of a rear end position relative to one another into a front end position and back again. The lap feed, first of all, passes under the feed roller. ERA comber .
