Question 6 (Textile Technology & Fibre Science)

In a comber, the component that rotates both in the forward and backward directions is

(B)Top comb
(C)Cylinder comb
(D)Detaching roller
[Show Answer]

Option D is correct.
The detaching roller in a comber machine is a component that is used to separate the fibers of the carded sliver and separate them into individual fibers. The detaching roller has a series of fine wire teeth that grab and separate the fibers as the roller rotates. The separated fibers are then passed through the licker-in roller, which removes any remaining noils (short fibers) and leaves a combed sliver. The combed sliver is of higher quality and uniformity compared to the carded sliver, and is used as the starting material for spinning to produce yarn. The detaching roller is an important component of the comber machine, as it helps to produce a higher quality end product and improve the efficiency of the spinning process.
