  • the lower portion of the tubular net body is pushed onto the part of the central tube 52 located within the storage container 51.
  • Lubricant or wetting agent 54 filled into the storage container 51 is conveyed upwards under the influence of the capillary action as long as the porous net body 53 is immersed in this wetting agent, so that threads sliding along the crowned surface of the net body 53 are wetted with the wetting agent.
  • the supply of wetting agent within the storage container 51 is used up, so that wetting agent must be refilled from time to time.
  • the storage container 51 is provided with an internal refueling chamber 55 which has an opening 55.1 on its upper side and a downwardly directed cylindrical bore 55.2 in its bottom, which merges into a conical opening 55.3 which widens outwards.

  • the aviva head 50 is gripped and held by the upper gripper 37 attached to the suction device 23, which has two gripper arms 37.1, 37.2 which can be pivoted in the horizontal direction.
  • the gripper arms 37.1, 37.2 of the upper gripper 37 are provided with inwardly directed projections or lugs 38 which, when the gripper arms are closed, engage point-wise in an annular groove 51.2 of the aviva head 50. This ensures that a thread that runs along the outside of the aviva head 50 and runs into the center or the hollow axis of the aviva head at the top is not clamped by these gripper arms 37.1 or 37.2.
  • Air lines are integrated in the lower gripper 22 or in its gripper arms 22.1 and 22.2 and in the suction device 23, through which either for the pneumatic actuation of the gripper arms or cutting devices, not shown, can be supplied with compressed air, or in which a suction air flow can be built up in order to suck off cut thread ends.

  • the filler neck 47 lifts the valve body 56 of the aviva head 50 against the force of the compression spring 58 from the valve seat, so that a connection between the refueling chamber 55 and the inner bore of the cylindrical shaft 56.1 is made through the lateral openings 56.2.
  • This return and closing spring 58 is designed so that it exerts as much back pressure on the filler neck 47 from a certain path that it dodges against the force of the spring 47.3 supporting it and thus opens the filler neck valve assigned to it. Because of the excess pressure prevailing in the storage tank 41, wetting agent 54 can now flow from the storage tank 41 into the storage container 51.
  • the wetting agent flowing into the storage container 51 displaces the air located above the wetting agent or conditioning level, which can flow out via the relief valve of the storage container 51 formed by the elements 60, 61, 62, 63 and 64.
  • the two valves close under the influence of their return and closing springs 58 and 47.3.
  • the filled aviva head 50 can then be moved back into the spindle area and onto the meanwhile inserted into the spindle with two full cross or Supply spools 6 fitted adapter lower part 5 can be plugged on.
