ABSTRACT:
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.
