VERFAHREN UND SPINNMASCHINE ZUM HERSTELLEN VON COREGARN
摘要:
A method and device for the production of core yarn (63), whereby a core yarn (12) is brought to a fibre slubbing (8) which has been refined in a drafting system before said slubbing is reinforced by twisting. The core yarn (12) is embedded in covering fibres. The fibre slubbing is compressed in a compacting device (22) after the core yarn (12) has been brought to the slubbing and before twisting occurs.
