12-strand ropes are made from any or all of the following fibers: olefin,
polyester, or nylon.
Machovec is proud to bring you information
on splicing rope. End-for-end rope splicing may be performed on new or used rope. This is an
all-purpose splice technique designed for people who generally splice used
rope as frequently as new rope. By following the procedure below, the
splice can retain from 90% to 100% of average new rope strength and in
used rope up to the same
proportion of residual used rope strength.
Step 1...Marking Measurements
Tape ends of line to be spliced. Lay two ropes to be spliced side-by-side and measure one tubular fid length, (two wire fid lengths because wire fids are half size) from taped end of each line and make a markóMark
Mark 1 measure one tubular fid lengths (two wire fid lengths) and make
on both lines.
Mark 2 measure two tubular fid
lengths (four wire fid lengths)
and make Mark 3 on both lines.
Step 2...Tapering Tail
in the direction of the taped end of the line, mark every second right and
left strand* for three strands.
Cut every marked strand and pull out of line (tape at end can cause resistance and may have to be removed in order to pull out cut strands).
Tapered end will now have only 6 strands remaining. Tape tapered tail tightly to keep from unbraiding
during the rope splicing process.
*Larger rope diameters may have pairs of strands in right
and left direction. In this case, treat the pairs of strands as a single
strand, marking and cutting both in each direction as described
Step 3...Repositioning Ropes
Reposition ropes for splicing according to diagram below.
Step 4...Burying Rope A Into Rope B
Attach fid to tapered end of
Rope A and insert fid into
2 and bring out at
Then remove fid.
Pull tapered tail of
Rope A until you have buried up to
. With larger lines, once you have fid and tapered tail through the line, tie off tail to stationary object; then
use both hands and weight of body to bury Rope B up to
Leave tail sticking out
Step 5...Finish Burying
Attach tapered tail of
Rope B to fid. Insert fid into Rope A approximately the diameter of the line away from insertion point of Rope A into Rope B.
Bring fid and tail out at Mark 3 of
Rope A. Following same procedures as in Step 4 to bury Rope B up to its Mark 2.
Leave tail sticking out.
Step 6...Smooth Out Splice
Pull tails to tighten crossover. Then, smooth braid in both directions away from the crossover. Now cut off tailsócut tails on an angle so as to give them a point.
Give a final smoothing, away from crossover, stroking rope firmly. Tails should bury inside cover.
Rope splicing is a bit of an art, form as well as function.
LOCK STITCHING PROCEDURE
From mark 2 at crossover, count 8 picks in either direction and insert stitching twine.
Working towards the crossover, pass end "b" back and forth through splice until a minimum of two (2) complete stitches have been made on each side of crossover.
Tie an overhand knot in each tail, as close to its exit point as possible.
Insert tail of stitching twine at exact location where
twine emerges. Using needle or small fid, pull (or push) through rope at a slight angle. Pull hard on the end of the twine so that the knot disappears inside the rope. Trim off the remaining twine close to the rope.
We hope this information on splicing rope was helpful.
