Abstract:
In a device for measuring angles in a machine where a sheet-like workpiece is to be pressed to a certain angle by a relative direction of movement of an upper pressing tool and a lower pressing tool having an engaging edge and a center plane, the device comprises:(a) a shaft extending parallel with the engaging edge of the lower pressing tool;(b) a pivotably arranged asymmetric rocker supported by the shaft, the rocker having a sensing edge arranged to engage with the workpiece that is to be pressed to a certain angle;(c) a detecting mechanism directly connected to the shaft for sensing angular position of the rocker thereon;(d) a display device operationally connected to the detecting mechanism for displaying the angular position sensed by the detecting mechanism; and(e) a supporting and displacement device supporting the shaft and thereby the rocker and arranged to displace the rocker at right angles to the shaft and in an oblique direction in relation to the relative direction of movement of the upper pressing tool and the lower pressing tool whereby the rocker moves toward the center plane of the lower pressing tool upon upward movement in the oblique direction.
