摘要： A coiling machine (10) includes a material guide (12), first pin (13), second pin (14), pitch tool (15), cutting tool (16), heating device (17), temperature sensor (18), and controller. A material (2) continuously discharged from a tip (12a) of the material guide is bent between the first pin and the second pin to form an arc part (2a) between the first pin and the second pin. The controller select control data corresponding to the temperature of the material detected by the temperature sensor from a plurality of control data corresponding to a processing temperature. Then, the positions of the first pin and the second pin are controlled such that a radius of curvature of the arc part increases when the temperature of the material increases, and the position of the cutting tool is controlled such that a gap between the center of curvature (C1) of the arc part and the cutting tool increases.

摘要： A coil spring modeling apparatus (20) includes a first attachment member (21) disposed on a lower spring seat (10A), a second attachment member (22) disposed on an upper spring seat (15A), an actuator unit (30) formed of a Stewart-platform-type parallel mechanism, a hydraulic pressure supply device (37), a torsion detection mechanism (40A), and a controller (70). The torsion detection mechanism (40A) is constituted of displacement gauges (40 1 -40 6 ) such as a linear variable differential transformer (LVDT). The displacement gauges (40 1 -40 6 ) are provided on hydraulic cylinders (31 1 -31 6 ), and detect amounts of displacement relative to the reference lengths of the hydraulic cylinders (31 1 -31 6 ), respectively. The controller (70) calculates a relative torsional angle between the first attachment member (21) and the second attachment member (22) based on the detected amounts of displacement.

摘要： A favorable appearance can be achieved using a simple configuration, even when the configuration is provided with a back shell that moves up and down relative to a back frame. In a vehicle seat 10, the back of a seated person is adapted to be supported by a movable back shell 42 that is supported so as to be capable of moving in an up-down direction relative to a back frame 30. A non-movable back shell 46 that is attached so as to be incapable of displacement relative to the back frame 30 is disposed on a back face side of the movable back shell 42, and the back frame 30 is covered by the non-movable back shell 46.
