| (54) | Device for multi-component yarn production in a rotor spinning machine and sensor for rotor spinning machines producing the multi-component yarn |
| (57) 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. |
