Hi Marks and dear all, thanks for your comments and suggestion.
I think at this moment I will not make notes with loop chirality or handedness of the bends because each of these bends possess a few loop formations and of course will have different loop chirality descriptions. Such as Zeppelin Bend has 6 loops forms, Rigger's Bend has 8, Ashley's Bend has 6 etc.
Starting from the beginning, I aim to do the OTHER tying methods, they are differ from the known tying methods. I have had delivered some startings and tying methods in My Working Notes such as Ends Crossing, Opposite, Parallel, Twist, Spiral Drops, Pecking Duck ... These starts tying methods will access to different loops formations of bends. Also at the finished ends tuckings they are either in crossing, non crossing, twisted elbow or not, the results will be different and becomes another bend.
You may use my loops formations charts to name out their loop chirality. I always think that the chirality description applied to some loop knots and bowlines are most adequate as each knot is with one SP and one WE. But for the bends, apart from my mentioned reasons above (different starts tying methods) , each bend is with two SPs and two WEs and each may pointing differently to four directions North, South, East and West (64 sets are worked out).
About Bends of superposed are of Types 1 and 2, and the Bends of interlocked type are of Types 3 and 4. They are tabulated in my Loops Formations Charts of Bends in "My Working Notes 5".
You can find out the difference if the loops chirality is changed or reversed in the chart also. But except two bends, though the loops chirality is changed or reversed, the bend remain unchanged (but reversed and mirrored). They are Alpine Butterfly Bend and Y-lock Bend.
About the terms used to describe chirality, I prefer to use S twist loop and Z twist loop. For the terms S twist and Z twist are common and universal used in rope, cable and screw threads.
