In normal lock stitch machines, tailors/sewing operators need to use a trimmer or scissor to cut the needle and bobbin thread after completing the stitch. But with UBT functions, operators just need to push a button or press the paddle back to trim the thread.
Now all the machine manufacturers included UBT trimmers in their lock stitch sewing machines.
