Automatic backtacking (bartacking)
–
In the machines equipped with the positioning motor it is possible
to pre-select the backtacking by a pre-selected backstitches
number both at the beginning and at the seam end. At the seam
beginning (after the preceding thread trimming) after the pedal
treading forwards the machine sews the pre-selected bartack
entirely automatically. The same at the seam end after the pedal
treading in the position –2 the machine sews the pre-selected end
bartack and then trims the threads (see chapter 8).
