AutoGlassbot™ Loop Splicing Needles are mainly used to insert one piece of spectra line inside another. They can also be useful in 'opening up' the inside of the hollow spectra line so larger tools can be more easily used. Instead of being hollow inside, the loop splicing needle has a wire loop attached to its trailing end. Below is a picture showing the detail of the DaHo Loop Splicing Needle ends.
The needle is inserted into the line being spliced, and the end of the other piece of line is inserted into the needle’s wire loop. As the needle is inserted into the line being spliced, the other piece of line is pulled along with it. When done, the needle is brought out of the line being spliced, and the end of the line attached to the needle wire loop is tightened to complete one side of the splice, or the terminating loop, as the case may be.
