(2) Prior art In the prior art, beads were not suitable for forming the side edges of a blind system that moves at high speed along the guide rails without congestion. This has led to such shutter systems having to use a series of small, jointed, hard plastic blocks as their side edges. However, this solution is very expensive, especially because it is labor-intensive, and if the side edge accidentally falls off its rail, it must be re-inserted into the rail, and these small pieces have the risk of being easily damaged. . (C) Summary of the Invention One of the main objectives of the present invention is to provide an effective solution to this problem, which provides a continuous bead, which can avoid any obstacles, and can be manufactured on a non-labor-intensive automated continuous production scale . For this purpose, the side edges of the blinds of the present invention mainly include a bead having a core surrounded by a reinforced outer sheath and covered by a sliding agent. Preferably, the core comprises a porous material impregnated with a sliding agent such as polytetrafluoroethylene. In a preferred embodiment, the core contains polyamide, which is coated with a thin layer containing a sliding agent, such as by spraying. The present invention also relates to a bead that can be used in a blind system in which the side edge is moved in a guide rail, and it is mentioned in the scope of patent application. Other details and features of the present invention can be understood from the following description of specific embodiments of the blind system of the beading of the present invention, with reference to the drawings. (IV) Embodiments In many figures, the same symbols represent the same or similar elements. The invention also relates to a specific bead with a core covered by a slipper, and a shutter system with a specific bead on its side edge to move in a guide rail. In the first embodiment of the present invention, as shown in Figs. 1 and 2, the bead includes a core 1, which includes a soft yarn 2 extending side by side in the length direction of the bead, and includes a soft woven envelope 3 The diameter surrounding the yarn 2 and the core 1 is usually in the range of 3 to 8 mm, preferably 6 mm, which is surrounded by the reinforced outer sheath 4, which can reduce the coefficient of friction. The sheath 4 can be made of, for example, polyurethane. Finally, if necessary, a Teflon layer 9 whose brand name is Teflon can be applied to the outer sheath 4 by evaporation. When the bead must be moved in a guide not shown in the figure, it can be reduced. The coefficient of friction of the bead surface. The bead cooperates with a sliding belt 5 which extends transversely over the entire length of the bead and is fixed by the strip 6 on the plane 7 of the bead's axis 8 200408758 widened . The sliding belt 5 is made of polyamide cloth, which extends around the core 1 to form the latter outer sheath. This weaving thread is more slippery than the weaving slipper 5 of the outer sheath 4, and is preferably coated by evaporation and impregnated with polytetrafluoroethylene. The fixing strip 6 is usually made of a thermoplastic plastic, which can form side edge protrusions in the lateral direction of the shutter system 16. Fig. 3 shows a second embodiment of the bead of the present invention, which is different from the first embodiment as a core 1 and is made entirely of soft polyurethane, and at least an outer layer thereof is porous. As described in the previous embodiment, the sliding strip 5 widened by the fixing strip 6 extends laterally over the entire length of the bead. These slip bands 5 are made of polyurethane as well as the core 1, and are integrated with the core. The surface of this core and the sliding belt 5 are thermally impregnated with polytetrafluoroethylene, as shown by symbol 9 in FIG. 3. The thickness of the polytetrafluoroethylene layer thus formed is usually about 20 to 60 micrometers, preferably about 40 micrometers. The fixing strip 6 integrated with the sliding belt 5 does not contain PTFE impregnation, and it can be fixed to the side area of the shutter system 16. Fig. 4 is a cross-sectional view of a third embodiment of the present invention and is at right angles to the axis of the guide rail. The main difference between this embodiment and the second embodiment is that in the former, the bead has an extension of the driving belt 10 extending to the sliding belt 5, and the fixing strip 6 is opposite to the bead in the radial direction. In this embodiment, the drive belt with a concave-hole belt 11 and the drive belt 10 are integrated into 200408758, which is connected with the drive system. In order to make the driving belt 10, especially the concave-hole belt 11 relatively resistant to compression in its longitudinal direction, and to ensure its limited plasticity, the driving belt 10 has internal reinforcement 17. This inner reinforcement 17 comprises glass or aromatic aramid fibers, such as Kerlar, extending along the length of the drive belt 10. The composite body formed by the beaded core 1, the sliding belt 5, the fixing belt 6, the driving belt 10 and its belt U is molded into one piece, and is made of polyurethane. In addition to the fixing strip 6, this composite is impregnated and covered with a polytetrafluoroethylene layer 9. The drive belt 10 and its beads move inside the guide rail 12. The drive system is fitted near the upper end of the drive path and includes a sprocket 13, which rotates on a horizontal mandrel 14 parallel to the plane of the shutter system 16, as shown in FIG. An arc-shaped shield 15 is concentric with the sprocket 13 and extends above the guide rail of the extension, not shown in the fifth figure. The inner surface of this shield 15 is also covered with a Teflon layer 9. The experiment of the present invention proves that when the polytetrafluoroethylene is thermally applied to the sliding surface of the open pores, it will penetrate the pores to a certain depth. When the polytetrafluoroethylene layer is worn on these surfaces, it can be replenished at any time by the continuous movement of the polytetrafluoroethylene contained in the pores on the surface. It is believed that the present invention is not limited to the above embodiments shown in the drawings, but many other changes can be made without departing from the scope of the present invention. Because of 8-200408758, in addition to PTFE, other slip agents can be used. In other aspects, in some cases, an outer sheath made of a pre-impregnated slip agent or a woven yarn consisting mainly of a single yarn containing the slip agent may be installed on the core.
