  • Back latching (BK) means special contruction of stitch plate which enables use of thread remained after sewing a piece of fabric. Because of back latching the seam is more durable and resistant to unstitching.

    But you can use this machine as a regular overlock (stitch type 514). Using back latching is an option.

  • what is the meaning of back latching? what is it and different then the regular overlock 4 thread stitch?

    thanx
