Abstract: A device for placing a cop with its yarn pulled out into a compartment of a movable storage point from a step-by-step conveyor comprising a retainer for the end of the yarn when found, a fork which can be positioned at an angle and which laterally and alternately cooperates with the compartments of the movable storage point and of the step-by-step conveyor, pincers which can be opened and which retain the end of the yarn when found integrally fixed to and located on the top of each compartment of the movable storage point, a verifier of the presence of the end of the yarn, shears for cutting off the excess part of the end of the yarn and a control device for discharging a cop of which the end of the yarn has not been found. The verifier acts in cooperation with the shears and the control device.

Abstract: A device for aligning cops which withdraws them in bulk from a storage bin consisting of a substantially horizontal conveyor belt which discharges the cops onto a second elevating conveyor belt, which acts as a first spacing means. After the second elevating conveyor belt, the cops are further spaced out by two conveyor belts and are delivered one at a time along their axis into a collection chamber, from which they reach the usage means by passing over a sloped collection surface.

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.
