Method and apparatus for intermediate yarn storage during renewed spun thread joining

In a textile spinning apparatus comprising a spinning and winding machine, an apparatus for storing yarn being spun and delivered to a yarn winding device during the course of a yarn end joining operation, the apparatus comprising a spinning mechanism for spinning a new yarn from a newly delivered sliver, a mechanism for drawing the new yarn off at a selected speed in a path of travel toward the winding device, first and second yarn storage members disposed successively downstream of the spinning mechanism along the path of yarn travel, a yarn end joining mechanism disposed downstream of the storage members and a mechanism for controlling the travel of the yarn, the travel control mechanism nipping with rollers the travelling yarn at a position between the first and second storage members and being programmed to brake the travel of the yarn, after the second suction storage member is filled with yarn to a predetermined level, for a predetermined period of time such that the travelling yarn is suctionably stored within the first storage member during the yarn end joining operation and programmed to accelerate the travel of the yarn after the braking such that the stored yarn is removed from the first storage member and delivered to the winding mechanism.

In a textile spinning machine wherein yarn spinning and wind-up is begun by joining a yarn end from a newly spun yarn with a yarn end retrieved from a spun yarn on a yarn winding device, the newly spun yarn being continuously drawn off and delivered along a path of travel to the winding device during the course of yarn end joining in a joining device, a method for temporarily storing the continuously drawn off yarn during the course of yarn end joining comprising guiding the newly spun yarn being drawn off past a first downstream yarn suction storage member and a second downstream yarn storage member, the yarn end joining device being downstream of the storage members, braking the travel of the yarn being drawn off with rollers at a position between the storage members such that the yarn being drawn off is suctionably stored in the first storage member, after the second suction storage member is filled with yarn to a predetermined level, during the course of thread joining operations and then subsequently accelerating with rollers the travel of the yarn at the position between the storage members after the yarn joining operations are completed to remove the yarn stored in the first storage member.
