for a needle 4 that is put on the bore hole of the rotary thread take-up
disc to butt against the right surface 3.

–
Loosen the screws on the belt pulley 5.
–
Push the needle 4 through the bore hole in the rotary thread
take-up disc 6.
–
Turn the rotary thread take-up disc until the needle 4 butts against
the surface 3.
