  • Patent number: 4391360
    Abstract: The invention is concerned with a machine for drawing yarn hanks from advancing hank carrying supports and doffing the drawn hanks on a carriage or container or conveyor belt. The machine comprises a pliers holder head wherein the pliers, each formed of two or more rods movable near one another, can be adjusted in spacing for adaptation to various dimensions of hanks. The head is rotatable about a horizontal axis to arrange the hanks in horizontal direction and is tiltable or upsettable about a further horizontal axis. Furthermore, the head is mounted to be movable parallel to the extension of the hank carrying supports, and preferably also parallel to the advancement or feeding of the hank carrying supports.

  • Patent number: 4349309
    Abstract: A rotating device for rotatably transferring yarn skeins or hanks from a first generally stationary support or carrier to a second generally movable support or carrier, the latter being substantially at the same level as the first support or carrier, comprises a vertical structure, carrying two slide guides parallel to the movement of the second support; thereon a carriage having a rotating head is movable and has a rotating frame with two slide bars integral therewith; a rod carrying slider moves forwardly and backwardly on the bars, and carries two skein-holder rods which are parallel to each other and can be moved toward and away from each other. Preferably, the rotational movement is given by a cylinder-piston assembly between the vertical structure and an eccentric location on the rotating frame.
