Abstract: Thread-guide device with modulated traversing with an individual thread-guide with a back-and-forth movement fixed to a cord open at the two ends and moved between two pulleys in an alternating clockwise/anticlockwise movement, each activated with its own electric motor, both motors being piloted in frequency. The pulleys are connected to springs which pull the thread-guide towards the centre of its run and which alternatingly accumulate and release energy with every run of the thread-guide.

Abstract: A hand manipulated tube which can be axially stacked and is able to sustain bobbins that can be stacked, one against another, at least for doubling and twisting operations comprising an outside section which is at least partially elastic radially and disposed circumferentially, and which bears protrusions positioned lengthwise in respect of an end face of a portion of the tube, and which extend radially outwards, an inner circumferential seat in the portion of the tube positioned in respect of the other end of the tube whereby the partially radially elastic side cooperates with the inner circumferential seat for the positioning of two axially stacked tubes, axial guides within the tube and possibly a radially guiding and tensioning element between one tube and another.

Abstract: The invention relates to a device for conveying cops and winding tubes at one and the same time between a spinning frame and the relative winding heads which comprises a powered closed-ring conveyor means revolving in a substantially horizontal plane along each side of the spinning frame between one end of the spinning frame and the point of delivery of the cops to the winding heads pre-disposed downstream from the spinning frame, a plurality of pins carrying the cops or tubes and anchored to a conveyor, guides for the pins and a loading/unloading station where the tubes are loaded and the cops are doffed from the spindles of the spinning frame. The cops are conveyed on one side of the closed-ring conveyor, whereas the tubes to be fitted to the spindles of the spinning frame are conveyed advantageously on the other side of the conveyor.

Abstract: A deflector for twisting double twisting spindles with pneumatic threading of the filament and with prepositioning of the rotating part of the spindle during the threading phase. Substantially between the circumference described by the wall containing the outlet port of the filament of the rotating part and the peripheral rim of the rotating plate is arranged at least temporarily an angular deflector in cooperation with the neighborhood of the radial plane in which is disposed the outlet of the filament in the rotating part cooperating through its extension with the neighborhood of the tangent to the curved rim of the rotating plate.

Abstract: The invention provides an injector having a suitably formed head which can partially penetrate through a lateral aperture in a spindle into the vicinity of a chamber containing an expansible capsule.Penetrating into the chamber, the injector laterally displaces the capsule and by injecting through a beak a fluid under pressure creates in the axial passage a negative-positive pressure necessary for transporting the filament.In the vicinity of the chamber there can advantageously be provided a mobile section which is circumferentially displaceable by a projection which is included on the head of the injector, when the injector penetrates or is penetrating the spindle.The injector is further provided with an arm which may be pivoted in the vicinity of the balloon container or on an auxiliary bench.

Abstract: A device for finding, extracting and temporarily positioning the end of the yarn in cops. More particularly, a device that uses single-cop compartments, which move forward in steps, and wherein the cops lie projecting from both ends of the compartments and already correctly oriented. The part on the end of the bobbin is affected by three actions to extract the end of the yarn, two of them being mechanical and the other being pneumatic. Subsequently all the wound yarn is affected by a sucking action so as to pick up the end of the yarn with certainty, wherever it may be. The operations are carried out in four successive stations, wherein the cops are kept in rotation between suitable mandreltailstock groups except in the third station, where the cops are halted.
