Process for spinning multicomponent yarn on spindleless spinning machine and apparatus for making the same

摘要

Method of spinning multi-component yarn on an open-containing core yarn and spun staple fibers consists in the fact that in the first phase zaprádá staple yarn restoring jejíhokontinuálního retraction, after which begins the second phase to its rotating spun end feed speed reduction core strand, thereby this priprede already drawn off for staple yarn and then gradually increase the speed of feeding the core yarn at a working speed of administration, which is kept below the rate of withdrawn delays of multi-component yarn core yarn. Equipment includes sprádacíjednotku the spinning rotor provided with an axial bore of the core yarn and the exhaust vypredenévíceslozkové yarn exhaust tube and a feeding mechanism (13) of core yarn (11) provided with a separate drive motor (14), whose control unit is connected to a control circuit (18 ) piecing staple yarn (25), whereby at the driver circuit is connected also break sensor (15), the drive feed roller (9) spring (22) and optionally at individuálnímpohonu and the spinning rotor (2).
