ABSTRACT:
A relatively short and improved multistranded rope member, commonly referred to as a pigging string, particularly adapted for rodeo applications and the like. The improved pigging string includes an integrally back spliced loop in one end thereof and is therein fabricated without twist bias to provide a smooth and reliable interconnection in a hard, yet pliable tying element for binding calves' feet during rodeo competition. The back splice is formed during twist fabrication of the pigging string in an intermediate section thereof and is so configured as to alleviate twist-ridges and loose strand lays which often interfere with maximum efficiency in use of pigging strings. Likewise, the pigging string is assembled in a taut configuration around the back spliced loop, then immersed in a preheated wax mixture prior to being post stressed during cooling. In this manner the pigging string provides the requisite tensile strength in a tightly wound, pliable embodiment affording a balanced use thereof as necessary where time is precisely recorded.
