  • the present invention relates to a method and device or mechanism for the removing of bobbins wound on tubes mounted on rotatable spindles and their replacement by empty tubes for the winding of additional bobbins.
  • invention is more particularly related to spinning frames such as ring spinning frames or flyer frames but it is not an essential feature of the invention that a process of attenuation of doubling or the like should take place in the particular machine whose bobbins are to be removed and replaced by empty bobbin tubes.
  • the invention accordingly consists of a method of removing bobbins wound on tubes from a series of parallel spindles of a spinning or twisting machine, placing the removed bobbins on a row of receiving means having the same spacing as the spindle, and, using the same tube gripping means that is used for removing the full bobbins to place empty bobbin tubes on the spindles, the sequence of operations being as follows:
  • the empty tubes after the full bobbins have been set down, are moved in the direction of movement of the gripping means.
  • the gripping means can cease to grip the tubes and they are then used to press the tub es'on to the spindles in a direction parallel to the axes of the spindles.
  • the invention also consists in an apparatus for dofling bobbins from a series of parallel spindles of a spinning or twisting machine, comprising bobbin tube gripping means, a row of bobbin receiving means having the same spacing as the spindles, and control means for causing the bobbin tube gripping means to fulfill the aforesaid sequence of operations.
