A device for joining textile yarns for joining two ends of two textile yarns by decomposition and subsequent re-composition of the twists of the fibers of the ends in order to make up a single yarn, including two counter-rotating components, each provided with at least one joining element and disposed opposite each other defining a joining zone defined by the area between the respective joining elements facing each other and substantially aligned along a work axis.

An improved system for moving the spools and tubes on the trays of automatic spoolers, where the spooling units composing the machine are at their outlet connected to a discharge circuit fitted with a switch capable of routing the trays on a return path, or switching them to a 'stand-by' circulation on the circuit.

A method for joining textile yarns to restore their continuity each time this becomes necessary in a winding unit, wherein the method is implemented in a joining device which operates several successive steps, one following another, to achieve a continuous connection. The individual operations involved in the method for joining being independent of each other and being autonomous and flexible in their implementation, each implemented step being subjected to an acceptance check based on predetermined quality standards before proceeding to the next operation in the same joining cycle.

A method and device for the continuous automatic monitoring and control of the tension to which yarn is subjected in a winding unit, in particular in an automatic bobbin winding unit, in which along the travel path the clamping force of the braking washers on the yarn is continuously and automatically controlled on the basis of parameters defining the type of yarn being wound and the operational, technical and geometrical characteristics of the feed package being unwound and those of the overlying bobbin under formation.

A conveyor system for an automatic coning machine having coning units for unwinding thread from spools carried by disks. The system has a feeding conveyor for transporting the spools on carrying disks to the coning machine and a removal conveyor for transporting exhausted spool carrying disks from the coning machine. Passages traverse adjacent coning units which are interconnected to and between the conveying and removal conveyors. Feeders are provided for, at least, the feeding conveyor. The feeders are connected to and movable with the feeding conveyor, wherein the feeders are spaced apart from one another and wherein each of said feeders includes an engaging member for contacting a spool carrying disk and moving the spool carrying disk along the feeding conveyor, and a jutting member movably connected to the feeder which contacts the engaged spool carrier disk for guiding the spool carrier disk in a desired position along the conveyor. The system also has a movable deflector operatively connected to each coning unit and its adjacent passage. The deflector is movable into the path of a spool carrying disk being fed along the feeding conveyor by the feeders for engaging and deflecting the movement of a spool carrying disk from a feeder when a spool carrying disk is required in the adjacent passage. Concurrently the deflector is movable out of the path of the feeder.

A conveyor system for an automatic coning machine having coning units for unwinding thread from spools carried by disks, wherein the system has a conveyor for feeding the spool carrying disks to the machine. A plurality of paths are connected to the feeding conveyor, wherein a path traverses an adjacent coning unit and includes a standby position adjacent the feeding conveyor for receiving spool carrying disks and an unwinding station at the coning unit for receiving spool carrying disks from the standby position. A positioning device has a pair of members positioned along the length and on opposite sides of each of the paths, wherein one of the members has recesses which are spaced apart for receiving a portion of the spool carrying disks at the standby and unwinding positions, and wherein the other of the members has protrusions opposite the recesses for engaging opposing portions of the spool carrying disks and for releasably urging the engaged spool carrying disks into the recesses, to thereby position the spool carrying disks at the standby and unwinding positions. A moving device is connected to the system adjacent each path and operatively connected to each coning unit, and the moving device is adapted to overcome the releasable engagement of the spool carrying disks by the positioning device in response to the exhaustion of the spool carrying disks at the adjacent coning unit and to move the exhausted spool carrying disk from the unwinding position and the spool carrying disk from the standby position to the unwinding position.

A method for automatically regulating a thread tension in a bobbin-winding machine having a lower pirn, an upper bobbin, and thread-tension devices, wherein during the entire time thread unwound from the lower pirn is collected on the upper bobbin in formation, the thread-tension devices press on the thread between the lower pirn and the upper bobbin with a pressure action controlled on the basis of a winding speed value of the thread.

A method and apparatus serves to wind yarn on a forming bobbin driven by a grooved drive roller in a collection station, in such a manner as to prevent ribbing during the continuous superposing of the various layers of winding, hence rendering the subsequent technical operations to be undergone by the bobbin yarn both possible and simple. The apparatus includes a control unit having a keyboard, a mini-computer and a motive source which angularly positions the bobbin carrier arm such that the collection station operates in regions not in proximity with regions undergoing a ribbing effect.

A device for sequentially loading tubes in a spinning machine wherein the tubes are fed by a tube orientating device. The device disclosed includes a duct for guiding the fall of the tubes and provided at its lower end with a shutter which loads one tube at a time onto the pegs of the spinning machine doffing belt by withdrawing it from a stack of tubes accumulated within the duct to form a buffer stock.

A device for sequentially loading tubes onto pegs on the doffing belt of a spinning machine having a tube orienting system which includes a duct for guiding the fall of the tubes, and a mobile dispenser comprising a plurality of compartments which receive the tubes from the duct load each from the duct and also load each tube onto the pegs of the doffing belt.

This invention relates to a device for preventing yarn loop formation and for saving the suctioning yarn on winding units. This device keeps the yarn under tension during the knotting and cone doffing steps. The device has a movable bar which is positioned adjacent to the upper end of a pirn during the unwinding process and which is shifted by an actuator to contact the pirn before the yarn is stopped. This is accomplished by keeping the yarn under tension from the pirn cone to a yarn-tensioning disc at the beginning ot the knotting and doffing cycles to prevent loops from forming. Additionally, this device limits the yarn consumption of the knotting cycle. By frictionally clamping the free end of the yarn with an anti-loop device, yarn is suctioned by a free yarn end feed nozzle in a shortened length thus limiting the amount of yarn removed and lost during a knotting cycle.

A bobbin support arm with modulation of the motion transmission between a roller and bobbin to prevent ribboning, by means of a rocker movement between the bobbin and roller determined by the oscillation of the arm both in the horizontal plane and in the vertical plane.
