Together with the top comb, the circular comb is the key technological component of the comber, influencing the characteristics of the yarn with respect to evenness, strength and cleanliness, which in turn have a direct effect on the finished product as far as softness, visual effect and grip is concerned.
To improve the quality of the end product it is essential for the comber to extract short fibres, neps and other impurities and to produce an even sliver. The combing intensity, also referred to as comber noil percentage, depends on the cotton processed and its staple characteristics. It is the aim of the combing process to comb out as little as possible to achieve the optimal result for the intended application and the cotton processed.
The circular comb combs out the protruding part of the fibre fringe which is held by the nipper. In the process of transporting the fibre fringe to the detaching roller, the top comb combs out the part of the fibres previously clamped by the nipper.
PRIMACOMB
Years of research have resulted in the development of the PRIMACOMB high-performance circular comb.
COMB-PRO
These circular combs have been developed for combers that run with maximum speed of 400 nips/min.
Ri-Q-Comb
The latest generation of circular combs has been developed in co-operation with Rieter for their most recent E80 comber. The highlight of this circular comb surely is the increased combining surface of 130 degree, which allows an optimum combing action.
Ri-Q-Top
Todays generation of high performance combers puts increased demands on the two key components in the combing process, i.e. circular and top combs. It is only due to the special configuration, the precision and the special finish of these key elements that the increase in production rates as known today can be realised with the same or improved technological values.
FIXPRO
The FIXPRO top comb is constructed identically to the Ri-Q-Top and is designed to preferably complement the COMB-PRO circular comb. Graf provides the entire scope of circular and top combs to cover all requirements and applications. Great efforts are undertaken to develop new circular and top combs to assure perfect components for the latest, but also for older types of combers.
