Device for multi-component yarn production in a rotor spinning machine and sensor for rotor spinning machines producing the multi-component yarn

摘要

The device for multi-component yarn production (5) comprising a continuous component (4) and a component spun in the rotor (3) from singled-out fibres (21) on a rotor spinning machine whose operating unit contains means for preparation of singled-out fibres (21) from sliver (2) and for their transport to the spinning rotor (3), where they are processed into a spun component, whereas the operating unit further contains means for supplying continuous component (4) to the spinning rotor (3) and means to draw off the spun multi-component yarn (5) and winding it onto the bobbin (71), while in a path of the continuous component (5) a sensor (10) of the continuous component is inserted and in path of the multi-component yarn (5) a sensor (8) of the multi-component yarn is inserted. The path of the continuous component (4) in the area of the sensor (8) of the multi-component yarn (5) is situated close to the path of the multi-component yarn (5) and in the area where the continuous component (4) is situated near to the path of the multi-component yarn (5) the continuous component (4) has a sensor (10) of the continuous component.
