Automatic backtacking (bar sewing, bartacking)
On machines equipped with the positioning motor and automatic

pre-selected number of reverse stitches both at the beginning and at
the end of the seam. At the beginning of the seam (after previous
thread trimming) after the pedal treading forwards the machine will sew
the pre-selected bar and continue the sewing. At the end of the seam it
will sew the pre-selected bar at the pedal treading in position -2
(see section 7.11).
