Threading up from the Bobbin Board to the Yarn Carrier
Course of yarn
The yarn feeding is carried out from the top - directly from the yarn control unit to the yarn carrier.
To prevent the threads from touching each other, the yarn control units are arranged in a V-shape.
Course of yarn
The course of yarn from the bobbin to the yarn carrier should run straight.
Definition of the allocation of bobbin - yarn control unit - yarn carrier:
- Bobbin 1 - Yarn control unit 1 - Yarn carrier 1
- Bobbin 2 - Yarn control unit 2 - Yarn carrier 2
- etc.
This yarn feeding causes:
- the most reduced yarn tension possible
- that the threads do not touch each other
Example on equipment: of an ADF 32 W:
- Bobbin boards for a total of 32 yarn bobbins
- 32 Yarn control units
- 32 yarn carriers (2 yarn carriers on 16 tracks)
This means: If several threads are combined in one yarn carrier it is no longer possible to use all of the 32 yarn carriers.
