With the drive element that can Swiveling the package or the sleeve into the Winding position for the winding process are effected. At the same time With this movement, the energy store can be filled. During the winding process, the contact pressure between Cross-wound bobbin and drive roller with the drive element can be controlled at the same time so that the pressure curve on the Coil structure is matched. Another function can do that Drive element with the pivoting of the coil frame also over a large swivel range in a removal position for the full bobbins.
  • a lever-shaped locking element is compact and space-saving and is well suited to accommodate one Lifting cylinder.
  • the locking element rotates on the shaft coupled, form the imaginary center lines of lever and Locking element preferably an angle between 10 and 90 degrees, especially around 45 degrees. In this way, the Release the lever after uncoupling the locking element of energy of the energy store which is the contact between the Especially the spool and the roller-canceling swivel movement generate effectively.
  • the device according to the invention provides a compact, space-saving and cost-effective solution.
  • the desired one The contact between the roller and the package can be removed in the event of a power failure with the device quickly and safely cause and impairment of the upper thread detection, Damage to the thread and thread position errors can thus be avoided become.
