Abstract
A novel and superior lariat and lariat rope body for calf and steer roping having a core of monofilaments in the center around which three or more strands of twisted monofilament yarns are wound tightly to form the rope. A novel method of making lariat rope bodies and apparatus used are also disclosed. The rope body has a core in at least about 68 percent of the length of the rope body beginning with the honda end.
Claims12
The method of making a lariat rope body wherein three or more strands comprised of a plurality of twisted, plied and/or cabled monofilament yarns are wound around a core to form a rope structure, the core being in at least a critical portion of the rope structure, at a winding site, the core being comprised of a plurality of monofilaments, the total denier of the monofilaments in the core being at least about 30,000, the winding taking place while said strands are under tension and while a portion of each of the strands is under compression at the winding site, each strand being made by twisting a bundle of said monofilament yarns under tension throughout the length of each strand during the winding, the strands are wound around each other in any portion of the rope containing no core, the critical portion of the rope structure being at least about 68 percent of the total length of the rope structure, securing each end of the rope structure to prevent the rope structure from unwinding, removing the rope structure from the winding site and submerging the rope structure in a hot, molten wax for a period of time to allow the molten wax to penetrate the strands, removing the hot, wax-penetrated rope structure and holding it straight while it is allowed to cool to form a lariat rope body.
A method of making a lariat rope body comprising winding under tension strands of twisted monofilament yarns around each other to form a rope structure, securing the ends of the rope structure to prevent unwinding when the tension is removed, submerging the rope structure in hot molten wax for a period of time, the temperature of the wax being sufficiently high to relax the stress in the rope structure that would tend to make the rope structure curl and to reduce the viscosity of the molten wax to allow the wax to penetrate the strands, and removing the hot wax impregnated rope structure and holding the hot wax impregnated rope structure straight while it cools to form a lariat rope body, the improvement comprising:
- winding three or more twisted strands under tension around a core to form a rope structure, said strands comprising twisted monofilament yarns throughout the cross section of each strand and said core comprising monofilament yarns with the total denier of monofilaments in the core being at least about 30,000, the core extending throughout at least a throwing portion of the rope structure.
A method of making a lariat rope body comprising winding under tension strands of twisted monofilament yarns around each other to form a rope structure, securing the ends of the rope structure to prevent unwinding when the tension is removed, submerging the rope structure in hot molten wax for a period of time, the temperature of the wax being sufficiently high to relax the stress in the rope structure that would tend to make the rope structure curl and to reduce the viscosity of the molten wax to allow the wax to penetrate the strands, and removing the hot wax impregnated rope structure and holding the hot wax impregnated rope structure straight while it cools to form a lariat rope body, the improvement comprising:
- winding four or more twisted strands under tension around a core to form a rope structure, said strands comprising twisted monofilament yarns throughout the cross section of each strand, the monofilaments in the strands being mostly or entirely nylon material and the total denier of the monofilament yarns in each strand being in the range of about 104,000 to about 137,000 and said core comprising mostly or entirely polyester monofilament yarns with the total denier of monofilaments in the core being in the range of about 45,000 to about 65,000.
