Abstract
Introduction. The low purity of combing flax seed balls with flax harvesters is a problem for the technological operation when harvesting fibre flax. The analysis of the comb designs of the combing units made it possible to identify the main disadvantages that do not fully meet the agrotechnical requirements for harvesting fiber flax. An innovative design of a removable comb for single-rotor drum-type harvesters is proposed.
Aim of the Study. The study is aimed at determining the purity of combing the standing fiber flax stems using a single-rotor comb-dresser with removable combs.
Materials and Methods. There has been made an experimental setup to simulate the process of combing standing fiber flax plants with combs of a single-rotor comb dresser. During the period from 2018–2023, the design parameters and operating modes of the combing unit were investigated and justified. There has been developed a technique for conducting a multifactorial experiment to determine the purity of combing fiber flax using a combing drum-type unit with removable combs.
Results. The results of laboratory studies on the separating flax balls from the standing fiber flax stems by removable combs are presented to determine the combing quality. It has been found that the purity of combing fiber flax plants is up to 99.2%.
Discussion and Conclusion. When studying the technological process of combing Nadezhda standing fiber flax plants the with single-rotor drum removable combs, the physico-mechanical properties of the flax stems were studied in laboratory conditions, the optimal operating modes of the combing drum were determined, which ensure the purity of the stems above 98% that meets the agrotechnical requirements for flax combines.

Keywords: removable combing comb, flax, combing purity, installation gap, combing drum
