 1995 (hereinafter, the "Canron device"). The Canron device differs from the Hepburn device, inter alia, in that the safety pin for arresting withdrawal of the lift pin from within the throughpassage is upwardly inserted into the bore in the lift pin, to a locked position, and is arrested from falling out of the bore by a spring-loaded ball bearing. The Canron device resolves, to a limited extent, the problem caused by rotation of the lift pin in the throughpassage. However, the Canron device does not resolve the problem of undesirable load release caused by inadvertent application of tensile force upon the pull line. The disclosed invention is directed toward bale forming belts on round hay balers. More specifically, the invention is a bale forming belt with an improved transverse stiffness and excellent fastener retention.
This invention addresses the need to make the bale forming belts on round hay balers stiffer in the transverse direction. The increase in transverse stiffness counteracts the tendency of the belts to roll over on itself causing damage to the belt and shortening the service life of the belt. Also transversely stiff belts maintain their position on the machine when slack, i.e. very low tension, conditions occur during baler operations. Increased transverse stiffness has long been recognized as a desirable feature in belts used on round hay balers. Manufacturers of these balers have historically advised belt producers of their desire for improved transverse stiffness to enhance the operation of round balers.
Increased transverse stiffness must be achieved without a loss of fastener retention. The belts must have excellent fastener holding properties, both as measured by static pull tests and by dynamic tests. The fastened ends of the belt represent the critical point for maintaining service life of the belt.
The increased transverse stiffness ideally should also be achieved in combination with optimized longitudinal flexibility. The hay baling belts should have sufficient flexibility to enable the belts to run around the relatively small pulleys of the hay baling machines.
The most effective method of increasing transverse stiffness is to use extruded monofilament cords of polyester, nylon, glass, or other material in the outside plies of these multiply belts. The monofilament cords are oriented in the transverse direction.
Current technology, as seen in U.S. Pat. No. 4,518,647, uses outside plies that contain 100% monofilament fill cords. While this approach achieves dramatic transverse stiffness in the belt, there are shortcomings in the physical properties and cost of the
1995 (hereinafter, the " Canron device "). The Canron device differs from the Hepburn device, inter alia, in that the safety pin for arresting coitus interruptus of the ski tow pin from within the throughpassage is upwardly inserted into the tidal bore in the lift pin, to a locked position, and is collar from falling out of the bore by a give - loaded ball charge. The Canron device resolves, to a limited extent, the trouble caused by rotation of the lift pin in the throughpassage. However, the Canron device does not resolve the problem of undesirable load release cause by inadvertent application of tensile effect upon the pull line. The disclosed invention is directed toward bale form belts on round hay balers. More specifically, the invention is a bale forming belt with an improved cross stiffness and excellent fastener retention. 
 This invention addresses the need to make the bale forming knock on round hay balers stiffer in the transverse direction. The increase in transverse stiffness counteracts the tendency of the belts to roll over on itself causing price to the belt and shortening the servicing life sentence of the belt. Also transversely potent knock maintain their position on the car when slack, i.e. very low tension, conditions occur during baler operations. Increased transverse stiffness has long been recognized as a desirable feature in knock used on orotund hay balers. manufacturer of these balers have historically advised belt producers of their desire for improved cross stiffness to enhance the operation of round balers. 
 Increased transverse stiffness must be achieved without a loss of fastener retention. The knock must have excellent fastener halt properties, both as measured by inactive pull trial and by dynamic test. The fastened end of the belt represent the critical point for maintaining service life sentence of the belt. 
 The increased transverse stiffness ideally should also be achieved in combination with optimized longitudinal flexibility. The hay baling belts should experience sufficient flexibility to enable the belts to ladder around the relatively small pulleys of the hay baling machine. 
 The most effective method of increasing cross stiffness is to use extruded monofilament cords of polyester, nylon, glass, or other material in the outside ply of these multiply swath. The monofilament cords are oriented in the transverse direction. 
 Current technology, as seen in U.S. Pat. nobelium. 4,518,647, uses outside plies that contain 100% monofilament fill cords. While this approach achieves dramatic transverse stiffness in the knock, there are shortcomings in the physical properties and cost of the
