Does increase the diameter of the rope substantially. Unlike bends, splicing retains most of the strength of the rope (85 to 90%). Excellent splice for repairs along headropes & footropes of various nets.

A 3/8 inch diameter yellow polypropylene rope will be spliced to a 3/8 inch manila rope. It is 3/8 inch diameter yellow polypropylene rope will be spliced to a 3/8 inch manila rope. It is generally not advisable to use dissimilar ropes for actual field applications.generally not advisable to use dissimilar ropes for actual field applications.

When splicing large lines or synthetics such as nylon or Dacron, the When splicing large lines or synthetics such as nylon or Dacron, the strand ends may become frayed and difficult to work with. To guard strand ends may become frayed and difficult to work with. To guard against this, wrap them tightly with a turn of tape or a seizing.against this, wrap them tightly with a turn of tape or a seizing.

When cutting the excess strands off, do not cut so close as to cutting the excess strands off, do not cut so close as to allow the strands to untuck.allow the strands to untuck.

If the splice is to be tapered do not cut the excess strands at this time – follow the steps shown in the following slide.

If a tapered splice is desiredIf a tapered splice is desired you should allow an extra you should allow an extra 3-4 inches when unraveling the strands prior to intertwining the 3-4 inches when unraveling the strands prior to intertwining the two ropes two ropes (figure 1).(figure 1). A tapered splice is made by taking an A tapered splice is made by taking an additional 2 to 3 tucks after the minimum number while cutting additional 2 to 3 tucks after the minimum number while cutting away some of the threads from each strand before each extra away some of the threads from each strand before each extra tuck tuck (figures 5A & 5B).(figures 5A & 5B).
