摘要:
A device for producing a thread connection by splicing includes a splicing head having a splicing chamber formed therein in which a tension-proof thread connection is formed by mutually entangling, hooking, intermingling and/or wrapping fibers of thread ends, means for supplying heated splicing air to the splicing channel, and an adjustable heat source coupled to the splicing head.

摘要:
Method for the knot-free connection of two threads formed of textile fibers of limited length having at least one twisted fiber strand, including a splicing device for mutually tangling, intermixing and intertwining individual fibers of the two threads, which includes inserting the two threads coming from opposite sides into the splicing device, trimming the end of each thread to a predetermined distance from the splicing device, vibrating, loosening, combing and separating the thread ends into individual fibers, cleaning and spreading apart each thread end by blowing compressed air into the splicing device obliquely to the longitudinal direction of the individual fibers and by beating, pulling and tearing with mechanical and pneumatic stresses in direction toward the thread ends, withdrawing the prepared thread ends from opposite sides up to the splicing device, tangling, mixing and hooking the individual fibers of the two thread ends to each other to form a splice connecting the threads after setting the splicing device in operation, introducing a thread twist into the splice, and removing the connected threads from the splicing device, and a device for carrying out the method.
摘要:
Method for connecting an upper thread to a lower thread, which includes inserting the threads into a longitudinal groove formed in a chamber for connecting the threads with a thread feeder being movable from a thread receiving position to a thread delivery position, splicing the threads together in the chamber using compressed air acting on the threads from the side, securely holding the threads up to the application of the compressed air when the threads are inserted into the chamber uncrossed, and securely holding the threads which are inserted into the chamber during the splicing in the immediate vicinity of the chamber when the threads are crossed during movement of the thread feeder, and a device for carrying out the method.

An automatic splicer for spun yarn, including open end spun yarn. Opposite yarn ends for splicing are inserted in opposed yarn clamping devices, adjacent yarn loop pulling devices, in a splicing slot of a splicing chamber, adjacent mechanical combing devices and in yarn severing devices. Excess yarn is cut from the yarn ends by the yarn severing devices at a predetermined distance from the splicing slot and the yarn loop pulling devices are advanced to pull the ends of the yarns to the combing devices at which air is applied to the yarn ends to direct the yarn ends to the combing devices. The yarn loop pulling devices are then partially retracted to feed the yarn ends into the combing devices at a controlled rate of feed for combing the yarn ends progressively from their ends to a length corresponding approximately to the length of the subsequent splice. The yarn loop pulling devices are then advanced further to withdraw the yarn ends from the clamping devices and into alignment in the splicing slot in which compressed air is applied to splice the yarn ends. The combing devices are rollers with needle clothing and they may be driven by the force of the air that is applied to the yarn ends to direct the yarn ends to the combing devices. Yarn feed slots may be formed in the splicing chamber extending transversely from the splicing slot to combing devices, in which case the severing and application of air for directing the yarn ends may be performed sequentially for the two yarns to avoid both yarn ends being drawn into the same feed slot.
