    摘要： Disclosed herein is a bedding or seating product (10) having a spring core (12) comprising coil springs (26) having unknotted end turns (72, 74) made from high tensile strength wire. In each embodiment, the end turns (72, 74) of the coil springs (26) are generally U-shaped having one leg (76) longer than the other (78), the legs (76, 78) being joined by an arcuate connector (80). The springs (26) are oriented in the spring core (12) such that a long leg (76) of one end turn (72) abuts a short leg (78) of the adjacent end turn (72) prior to be wrapped in helical lacing wire (32). The high tensile wire enables the coil springs (26) to be manufactured using less wire than heretofore possible.

    摘要： A hollow coil spring and a method for manufacturing therefor can prevent corrosion at an inner surface and can improve product appearance.
    In an end sealing step, an end Wa is sealed by which the core material of the end Wa of a spring member W is gathered by machining. It is preferable that spinning be carried out as a machining. For example, a squeezing roller R is moved in an axial direction as necessary, while the end of the spring member W is pressed to the inside in a radial direction by the squeezing roller R. As a result, the end Wa of the spring member W is sealed as shown in Fig. 3 , and therefore, it is not necessary to use another member such as a lid member. For example, the end sealing step can be immediately carried out after an inner surface processing step. In a coil forming step after the end sealing step, formation of clearance can be prevented at the end Wa, even if the end Wa of the spring member W is gripped and the spring member W is wound around the rod.

    摘要翻译： 中空螺旋弹簧及其制造方法可以防止内表面的腐蚀并且可以改善产品外观。 在端部密封步骤中，密封端部Wa，弹簧构件W的端部Wa的芯材通过机械加工而聚集。 优选的是，作为加工进行纺丝。 例如，挤压辊R根据需要沿轴向移动，同时弹簧构件W的端部被挤压辊R沿径向向内侧挤压。结果，弹簧构件的端部Wa W被密封，如图1所示。 因此，不需要使用诸如盖构件的其他构件。 例如，可以在内表面处理步骤之后立即进行端部密封步骤。 在端部密封步骤之后的线圈形成步骤中，即使夹持弹簧构件W的端部Wa并且弹簧构件W缠绕在杆上，也可以在端部Wa处形成间隙。
