  Note :

  On a two-bar machine, for example, the back guide bar enters the needles earlier than does the front guide bar during the backward swing and it is therefore free to commence its overlapping movement earlier than the front guide bar. During the return swing the back guide bar is last to reach the line of the needles and it has therefore a much longer period of time in which to make its overlap. Advantage may be taken of this fact by making the pattern wheel slopes for the overlap much longer for the back bar than for the front bar.
