Abstract
The invention relates to an overfeed composite spinning device and method suitable for ring spinning and applications of the overfeed composite spinning device and method. The method comprises the following steps of: driving an overfeed mechanism by the rotation of a front roller so as to lead filament bundles or yarns to be overfed in the front roller; and then enabling the filament bundles or yarns together with synchronously feeding short fiber strands to go out of a jaw of the front roller to be twisted and combined into double-component composite yarns. The overfeed buckling wrapping effect of the composite yarns is obtained by adjusting the overfeed amount and the feeding angle of the overfeed mechanism. The device for implementing the method comprises a tensile controller for controlling the tensile force of the externally tied filament bundles or yarns, the overfeed mechanism and a synchronous displacement locator, and is capable of really fulfilling the purpose of forming the yarns through the short fiber strands by buckling wrapping. The composite spinning method is special, and easy to implement; and the corresponding device is simple in structure, can be conveniently installed, and can be used for the wrapping composite spinning of short fibers on a ring spinning frame.
