  • Patent number: 6694718
    Abstract: A yarn splicing device for producing a knot-free yarn connection, particularly with elastic yarns, comprises a splicing body (25) formed with a splicing channel (26) to receive the yarns to be spliced and having at least one compressed air inlet opening (29) for pneumatic splicing of their constituent fibers. Yarn clamping devices (43, 44) and cutting devices (41, 42) are provided adjacent the splicing channel. Preparatory nozzles (53, 54) act to prepare the yarn ends for splicing and pneumatically hold the yarn ends to be spliced. Restraining devices (49; 50) are arranged along the splicing extent of the yarn between the clamping devices (43; 44) and the preparatory nozzles (53; 54) to pneumatically resist contraction of the yarn ends up to the preparatory nozzle (53; 54). The number of unsuccessful yarn splicing attempts with elastic yarns thereby can be reduced.
