  • the stop means 12 further comprises a blade 12.2, which protrudes from the auxiliary body 11 via bearing surfaces 18 for placing the auxiliary device 10 on a winding tube 2 and thereby provides a stop plane 20.
  • the bearing surfaces 18 thereby form a channel element 14 which is open to one side, wherein a groove 18.2 is provided between the bearing surfaces 18.
  • the auxiliary body 11 has a functional compartment 16.1.
  • the functional compartment 16.1 may be provided as an opening, through which a power unit 16 can be introduced into the auxiliary body 11.
  • the energy unit 16 can preferably be a battery, particularly preferably a lithium-ion battery, via which energy for the alignment means 13 and / or an adjustability of the stop means 12 can be provided.
  • the auxiliary device 10 is a hand-held device which can be operated independently of a winding machine 4.
  • an auxiliary device 10 can be used, for example, for a plurality of winding machines 4.
  • the auxiliary body 11 may further be formed of a plastic, preferably a polyamide.
  • the stop means 12 may be provided integrally with the auxiliary body 11 or attached thereto.
  • the stop means 12 may further preferably be formed of a stainless steel.
  • the energy unit 16 and / or the functional compartment 16.1 are also advantageously in the context of the first embodiment and in the context of the embodiments of FIGS. 4 . 5 . 6 and 8th used.
  • Fig. 8 shows a method according to the invention for aligning a winding tube 2 to a reference 1 in a schematic representation.
  • placing 102 an auxiliary device 10 is provided on the winding tube 2, so that a stop means 12 of the auxiliary device 10 is brought into abutment with a counter-stop means 5 of the winding tube 2.
  • a common displacement 103 of the auxiliary device 10 and the winding tube 2 follows until an alignment of the winding tube 2 and the reference 1 via an alignment 13 of the auxiliary device 10 takes place.
  • a transfer 101 of the alignment means 13 of a deactivated state II in an activated state I in particular before placing 102 of the auxiliary device 10, take place.
  • individual steps of the method 100 can be repeated as often as desired, and the entire method 100 can also be repeated in order, for example, to align a plurality of winding cores.
  • the method 100 thus offers a flexible, simple possibility by means of the auxiliary device 10 to align the winding tube 2 at the reference 1.
