Abstract: A circular knitting machine for the production of high-pile fabrics having combed-in fibres is disclosed herein. The knitting machine has a needle cylinder carrying knitting tools, at least one carding means for combing fibres into the knitting tools, an exhaust hood disposed above the needle cylinder and intended for the removal of loose fibres and at least one component disposed within and/or outside of the exhaust hood and fastenable thereto by means of at least one strut, to substantially eliminate the danger of any accumulation of loose fibres on the strut. The strut has an airfoil configuration.
